Design Of A Pipe Climbing Robot Engineering Essay

Design Of A Pipe Climbing Robot Engineering Essay This technical paper explains the design process and simulation of a concept vehicle to drive inside a circular pipe of the desired configuration as shown in figure 1. The design is developed to facilitate; pipe climbing and carry an inspection of an inspection panel. This vehicle when operated will travel in a horizontal section of pipe initially, before entering the inclined part of the circular pipe. It then drives within 0.2m of the inspection panel and starts inspecting it with the help of an on-board camera. Specific equations and assumptions are used to monitor vehicle motion and system controllers are designed to enforce there is enough traction applied by the vehicle to grip the pipe and move forward. Figure 1 Pipe inspection Scenario Index Terms-design, linear actuators, multi-wheel drive, proximity sensor, robots Introduction Inspection and maintenance are essential in all industries. Failure to conduct proper maintenance could result in potential danger to workers and machines. Carrying out these inspections impose rigours hurdles in case of various industries where the conditions are unsafe for human workers, for example, inspection and maintenance in a nuclear industry, where the environment poses serious risk for the humans. The most common way for conducting these inspections in hazardous conditions is to use long manipulators which could be expensive. The alternate way of carrying these inspections is by using walking/climbing robots. Pipe climbing robots are advanced robots, which have the potential to climb inside/outside of a pipe to perform specific functions, where a normal operator cannot be used. The improvements in this sector have grown rapidly, since its a cheap and effective way for investigating various properties inside a pipe. An assignment has been assigned to design a concept vehicle to drive inside a circular pipe as in fig 1. This vehicle needs to enter the tunnel and drive to within 0.2m of the inspection panel and inspect the panel at the end of pipe. The vehicle must also carry a wire which is tethered. The climbing robots can be classified into four major categories based on their approach to climbing: adhesive, brute force fixture, spines and grasp. The robots with adhesive approach use a mechanism such as suction or an electromagnetic fixture on the climbing surfaces. The brute force robots use a mechanism to grab on to the structure and move forward. The spine group of robots use spines/multi-spines to attach themselves to the climbing surface so as to propel forwards. The last group of grasp robots use their own dynamic and kinematic state to grasp on to the engineering structure and moves forward. The present conceptual design can be categorised under grasping group of climbing robots. These robots consist of mainly two mechanisms, one to power the robot to move and the other to grip the surface of the structure. The mechanisms used to grip on to the surface can be facilitated by the usage of spring and v-shaped arm or longitudinal actuators. A v-shaped arm along with a compression spring is connected to the body of the robot. The compression springs tends to expand the arms, if the outer arm reaches the surface, it exerts a force normal to the contact of surface thus proving the traction for gripping the surface. In case of linear actuators various mechanisms are used to produce the linear motion of the arms to exert force onto the surface. The present design employs a linear actuator. It has longitudinal arms connected to linear actuators. The linear actuator is a simple rack-pinion mechanism, but consists of three racks to synchronise the outward motion equally in all three directions, thus providing an equal amount of force on each surface of the structure. A multi-wheel drive system is employed for the present case, as there is a need for requirement for more torque when the robot climbs the inclination part and to reduce the slip generated by the wheel. In the present case, the robot has five wheels and hence five individual motors, two on the bottom of the base, one on either side of robot and one at the top of the robot. When in operation the outer end of the wheels on all directions would be perfectly inscribed in a circle of 200cm when looked at front view. This mechanism coupled with linear actuators makes sure that at any instant all the wheels are in contact with the surface of the pipe thus providing maximum available traction for the robot. Robot model and modelling assumptions In the present concept of design the circular pipe is considered to be even and has a constant coefficient of friction throughout. Designing the robot requires a methodological approach to implement a professional structured robot is done by generating a CAD model of the robot. The components of the robot are selected with maximum care with feasible materials, since theoretical tests and scenarios can be modelled based on weight and dimension of the robot. After selection of optimum materials for robot, the design process is finished. The weight of the vehicle including the power source (batteries), on-board camera and computer controller along with other drive motors and actuators will approximately be around 1.8 kg. The dimensions of the robot while in operation are 0.275m in length, 0.2m in both width and height. The front part of the robot is designed in such a way that it gets inscribed in a circle perfectly during motion. To maintain perfect contact at all time the wheel positioning is very critical. Both the bottom wheels are place below the base of the robot to facilitate more space for other components such as power source, camera, controllers, sensors etc. The remaining three wheels are positioned perpendicular to each other on the actuator arm. The length of this arm can be varied using the linear actuator mechanism. In the present case this linear actuator mechanism is a simple rack-pinion mechanism. All the three arms are synchronised such that under operation the displacement of arms is equal in all directions. Four proximity sensors are used to calculate the distance between the surface of pipe and surface of the tyre. Three sensors are linked to one at each actuating arm in their respective direction. One sensor is linked to calculate the distance from surface of front tyre to the surface of the inspection panel. The three sensors on actuator arm are categorised into a single sensor unit (say sensor unit 1), while the other sensor (say sensor unit 2) is categorised separately. The categorised bill of the materials used is as follows Working of the robot Initially when the robot is at rest, all the three linear actuating arms are in contracted position. When the system of the robot is started, the sensor unit 1 present on the linear actuator arms calculates the distance between wheel and surface of pipe and sends the feedback to the on-board CPU. The CPU then sends a signal to increment the step motor to one step. This whole process of increment of steps continues until the wheel touches the surface of pipe and thus exerts a small normal force to grip onto that surface. Once this process is completed, drive motors of the robot are actuated. These motors are controlled by on-board CPU with the help of feedback from the sensor unit 2. All the five motors through a gear box connected to the wheels are powered with equal force, hence powering robot equally in all directions and sensor unit 1 ensures theres maximum grip available at the end of the actuating arms. The power to the motor is stopped once the sensor unit 2 senses the distance between the front wheels and the inspection panel is 0.2m, thus activating the camera to carry the inspection process. This whole process can be controlled using a manual operation panel or fully autonomous programmed GUI on-board. Simulation of vehicle dynamics The vehicle dynamics of the robot are established using specific equations for motion. This analysis is used to determine the performance capacity and capability of the robot. It also helps to calculate the velocity, force dynamics at any instance of time. Before using the equations a few assumptions are considered. The drag forces exerted on the body and wire are neglected. The drive force from the wheels is considered to be a constant ideal force, where wheel slip and wheel tyre deflection are neglected. The gravitational constant and the friction coefficient considered to remain constant throughout the process. The simulation emphasises more on the vehicle motion along the entire length of pipe including the inclined part of pipe. The terminology used for the following calculaitons are as follows Parameter Description Value mb Mass of robot 1.8 kg r Radius of the wheel 0.03m mw| mass of wire per unit length 0.2 kg/m Ub Coefficient of friction of body 0.5 Uw Coeffient of friction of wire 0.2 G Gravitational constant 9.81 m/s2 Ts Stall torque of motor 0.9 kg-m Wn No load speed of motor 38 rpm O Angle of inclination of pipe 40o Straight path A constant force is produced through five drive motors and is calculated as follows, where Fm is the force exerted by the motor, But the torque generated by the motor changes with velocity of the body. Torque at any time is given as Where w is rotational speed at that instant of time. W can be written in terms of velocity v of the body Since there are five motors present to power the robot, the net force exeterd by motors at any time is The frictional force (Ffb) acting on the body due to its own weight Frictional force (Ffw) due to mass of wire Where mw is mass of wire carried at that time and is calculated by using length l of distance travelled by the robot The resultant force(F) resulting in forward motion of the robot Acceleration(a) of the body is given by Velocity vf of the body is given by Displacement lf of the body is given by à ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€ š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦.

Titanic: Death of a Titan :: Expository Essays Research Papers

Titanic: Death of a Titan After years of construction and work, the Titanic was finally ready for her maiden voyage. The beginning of her voyage was to take place on the morning of April 10, of 1912 at approximately 10:00am. The firs of Titanic passengers began to board the ship. Most of these passengers were British residents who had journeyed to Titanic by means of transportation either that a boat train. The real precipitance came when the boat train arrived. People rich or poor were scattered all aver Southampton's bay, attempting to find their gangway. After the second and third class passengers boarded, the firs class passengers were to be escorted to their cabins. Approximately at 12:00pm Titanic was ready to set sail. After Titanic sets out into the open sea, her water displacement causes mooring ropes of the New York, which was a small ship, to brake. Which causes her stern to swing towards Titanic's mighty bow. Titanic official's quick actions prevent a catastrophic collision. After hours delayed th e Titanic finally sets sail into the open sea headed towards Cherbourg, France. The Titanic lowered her anchor when arrived at Cherbourg, France, at about 5:30pm of the same day. More passengers boarded the Titanic. At approximately 8:10pm Titanic raised her anchor and sailed towards Queenstown, Ireland. She arrived at Queenstown at around 11:30am of the next morning to pick up more passengers and 1,385 bags of mail as well. Now Titanic once more raised anchor and by 1:30 she was on her way to New York. It was 11:30pm of the night of April 14, of 1912. As Titanic sped through the darkness towards its doom, the majority of the passengers and crew had not the slightest inkling idea that they were in danger at all. The last games of cards were breaking up. The last conversations were ending. Most passengers were already in bed, but the few who remained, were heading towards their cabins. Though the passengers settled, the officers on the bridge kept a sharp look out for anything in Titanic's path. Ice reports had been sent to the Titanic all day form other ships but Titanic's wireless operators chose to neglect the messages and so Titanic sailed in to history. High up in the crows nest, were lookouts Fleet and Lee. They to kept a sharp look out. Fleet peered into the darkness. He saw an object darker than night it self, coming towards the Titanic.

Fate decides how you are born Essay

As with all Shakespearean tragedies, King Lear, lays bare all the possible permutations and combinations in human relationships. It is not uncommon to hear modern writers to lament the fact that Shakespeare has not left untouched any aspect of human interaction. The sub plot of Gloucester and his two sons, the legitimate Edgar and the bastard son Edmund is a curious complement to Lear’s own follies of trusting the outwardly affectionate and as a consequence alienating the sincerely loving child. The lesson of human nature this sub plot provides is about knowing when the bitterness towards an accident beyond your control takes primacy of purpose in your life. Edmund let his illegitimate status drive him to indulge in all villainous acts only to further the depravity of his soul. You might not be able to help certain circumstances that stigmatize your existence but the best way out of it is to lead a life of virtue and not resorting to illegitimate acts to get back at the world and the society that condemns you for no fault of yours. The essential difference between Lear and Gloucester is the motivation of the usurpers of their kingdoms. In the case of Lear, they are just greed and ambition. It is not quite that simple with Gloucester. He does love his illegitimate son Edmund and acknowledges his status as the young man’s father openly and publicly. But, every kind word and every single attempt at showing Edmund that he is loved by his biological father translates into a sting aimed at the circumstances of his birth. His entire personality is defined by the antipathy that kindness evokes in him. Through Edmund’s characterization, Shakespeare shows the readers that the stigma that affects any person and changes his personality traits need not necessarily be external. The stigma attached to any person tends to color his judgment, his motivation and actions for all his life and he continues to see the world and its actions through the refracted light of his yearning for legitimacy. Though it might be known to Edmund that whatever he achieves, legitimacy is one thing he shall never achieve as his status is indelible for all future. This drives him to a state where he wants to snatch things from his half brother, usurp his father’s crown and also help others in similar quests. One thing he fails to cultivate in all his life is a relationship based on trust. He can trust nobody and become trustworthy to no body in return. Failure to accept one’s station in life can be a great factor that evaporates any kindness and nobility from the soul which is what happens in the case of Edmund. The paradox of a mind consumed with one single purpose – retribution- aimed at world at large is brought forward elegantly in the soliloquy of Edmund before he sets up on his decided path of deceit. He wonders why he is not worthy in the world’s eyes and laments the fact that he can never be accorded the tag of legitimacy. EDMUND â€Å"†¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Why brand they us With base? with baseness? bastardy? base, base? †(1. 2. 11-12) But he fails to recognize the veil he is allowing to grow in his soul as he proclaims â€Å"†¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦. Edmund the base Shall top the legitimate. I grow; I prosper: Now, gods, stand up for bastards! †(1. 2. 20-22) Such evil intentions are enough to provide proof to Edmund that his mind is playing games with him and making him the slave of his deep rooted stigma of irregular birth and his yearning for legitimacy. But he fails to see them or perhaps, he wants to fail to see them. In the same context, Shakespeare also tries to invoke the belief held by man that stars and celestial events have a bearing on the behavior and relationships of man. GLOUCESTER â€Å"†¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦yet nature finds itself scourged by the sequent effects: love cools, friendship falls off, brothers divide: in cities, mutinies; in countries, discord; in palaces, treason; and the bond cracked ‘twixt son and father. This villain of mine comes under the prediction;†¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦.. †(1. 2. 101-108) It is an attempt by a father to hang on to his last vestige of love for his son by claiming that un natural or non-regular celestial events like eclipses had something to do with his son turning against him. In private, Edmund completely rubbishes any such possibility and laughs at the weakness of his father for attributing his misfortunes to stars and nature. In support of his argument he says that his nature would have remained the same even if he had been fathered under the auspices of the luckiest celestial combination EDMUND â€Å"when we are sick in fortune,–often the surfeit of our own behavior,–we make guilty of our disasters the sun, the moon, and the stars:†¦Ã¢â‚¬ ¦Ã¢â‚¬ (1. 2. 118-120) â€Å"†¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦. Tut, I should have been that I am, had the maidenliest star in the firmament twinkled on my bastardizing†¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬  (1. 2. 132-134) The treachery of Edmund and his subsequent blinding at the hands of Cornwall, alienation from his son Edgar all lead to a decidedly defeatist philosophical outlook in Gloucester and he tries to explain his misfortune by saying that Gods inflict pain and suffering on humans for fun and as a pastime. He laments GLOUCESTER â€Å"As flies to wanton boys, are we to the gods. They kill us for their sport. † â€Å"(4. 1. 37-38) He then decides to take his and asks the mad man (his son Edgar in disguise) to lead him to a cliff and let him jump from the heights to give up his life. Edgar cleverly takes him to a flat bit of land and pretends that he has let him jump, then quickly changes the way he speaks to make Gloucester believe that he has survived a fall from a great cliff because he was led by some angel posing as the mad man. Though far younger in age and having endured infamy and difficulties galore, Edgar had wisdom beyond his years and whenever his father falls prey to despair, he helps him out of it by explaining the meaning of life’s journey. When Gloucester decides that he shall go no further and shall prefer rotting in the same place, Edgar tells him that man’s duty is to endure and the journey can not be cut short for despair. Ageing, losing one faculties, suffering reversals are all part of life and shall not impede the journey. The success of a life well lived lies in the times that one has fallen and in spite of his fall, has managed to stand, dust himself off and started moving forward again, with hope in his heart that good shall overcome evil. It is well captured in Edgar’s entreaty to his father EDGAR â€Å"What, in ill thoughts again? Men must endure Their going hence, even as their coming hither; Ripeness is all: come on. † (5. 2. 9-11) After several trials and tribulations Edgar finally accosts his half brother Edmund when he is invited for a duel and vanquishes him without identifying himself. When there are questions all around about the accusations he hurled at Edmund – as the chief perpetrator of cruelty and brutality against his own father Gloucester – Edgar finally reveals that he is the originally noble blooded son of Gloucester and he explains the difficulties he had to endure and the compulsion of his to act like an almost naked mad man, the attempted suicide of his father Gloucester and how he managed to save him with most implausible of stories. In the midst of all this exchange one more facet of Edmund’s villainous treachery bears its evil fruit. EDMUND â€Å"Yet Edmund was beloved: The one the other poison’d for my sake, And after slew herself. † (5. 3. 272-274) Edmund managed to manipulate even the love of two married ladies for him and this ends in tragedy when Goneril poisons Albany and subsequently kills herself. Misery and tragedy is what results in every venture that Edmund starts out on because his heart is so corrupted with wanton revenge and retribution but it is directed not at any person but at the circumstances of his birth and his burning desire to camouflage it with a magnitude of achievements that border on fantasy. As he senses the end of his life, Edmund suffers a conscience attack and wants to do some good. He finally realizes that ambition coupled with treachery ca take one only thus far and no further. Nobility of soul and purpose always manages to carry the day and it is evident from the fall from grace and favor of Edmund all so suddenly in the last act of this tragic play. Just before he is challenged to a duel by his half brother Edgar, he issues an order to kill Cordelia and King Lear. He also plans to pass it off as an apparent suicide. When he finally sees the mayhem he has created and the result of his treachery leading to two sisters dying, one by poison and other by her own hand, his conscience beseeches him to do at least one good deed before he is dead. He entreats the gathering to send some one to stop King Lear and Cordelia being killed as per his orders. EDMUND â€Å"I pant for life: some good I mean to do, Despite of mine own nature. Quickly send, Be brief in it, to the castle; for my writ Is on the life of Lear and on Cordelia: Nay, send in time. †(5. 3. 276-280) The sub plot of Gloucester launches the main villainy of Edmund on to the main stage of the play and holds his evil nature central to all misfortunes, well helped by the human infirmities of King Lear’s two daughters. But it also cleverly counters the numerous noble characters of the play – Albany, Kent, Edgar- and the like. Evil wins several battles but ultimately loses the War. Good suffers several trials by fire but manages to hold its own at the end. Two kings who let flattery and suspicion take over their better judgments suffer the moist implausible of consequences and in this, Shakespeare leaves a lot of lessons for all future generations. He almost seems to list out some commandments about human nature 1. Thou shalt not fall prey to flattery – King Lear 2. Thou shalt not allow suspicion to encroach your judgment but shall seek out complete facts – Gloucester 3. Thou shalt not let bitterness pervade your soul, in acting with bitterness you invite bitter ends – Edmund Apart from all these, Shakespeare seems to ask us to evaluate at every step if our intentions and actions have the desired effect on the people who are affected by it. If you love, let not the love patronize or smother the loved ones. And as one learned professor confessed to a student conversationally â€Å"When in doubt about how to go about life, read Shakespeare. You might very well find the answer you need†

Personal life Essay

My dad and I have a warmer relationship than my mom and I. The relationship between my dad and I, is different than the relationship with my mom because ever since birth id always be with my dad. Having mostly done everything with my dad it got our relationship so close; I did not want to do many things with my mom. My dad would act like such a kid; it would make me feel as if he was my best friend. I feel closer to my dad, rather than my mom is because of our time spent together over the years. Also the valuable time spent getting to know each other thoroughly. There are lots of differences between the relationship I have with my dad versus my mom. I spend more time with my dad comparatively than my mom which makes a big difference to my relationship with each of them. Eating things my dad would eat, to being influenced to a big time hockey fan. My mom could not be as open and have a kid mind while playing with me. Being active for my dad is a big deal, therefore me and him always try to be as active as we can. For example we always play hockey in the backyard. On the other hand my mom is not too keen of being active herself. My relationship with my dad and mom, have several things in common. First, both are always trying their best for me. For example, they both work hard, so they can provide me with good food, shelter, and clothing. A second way in which they are similar is that they both make the utmost choices for me, even though I may think they are wrong or don’t like them.
