Programing

 

     When we finished building the Lego robot. It's time to let it move. It's challenging to find the correct instruction when I programed it. It shows each part as a symbol that looks similar but different from the real one. My program is based on the example that is given in the book. I let the program circulate and find out the function of each symbol.  I created the programing that allowed the robot to move forward, stop in front of the box, pull down the arm and move backward. We got the right program but it couldn't catch the box because the carpet is not smooth and it changed the way that the robot went. But after over 15times try, the robot got the box and get back.O(∩_∩)O~~

My robot

     This is the first robot we built by using a Lego EV3 programing robot. It took us a long time to put it together. It has a Programer that uses for programing every move that the robot did. Programer controls each part by using wire to send the messages and power to each electronic part that make the other nonelectronic parts move. It has an element that can manage the distance from itself to the nearest fraise which let the robot can stop at the right spot.

Introduction of Robot

     Now robots are a part of the world that we can't miss. Most of the robots are designed for the helping people to do less mechanical work to let people to free their hands and do higher level work. Some robots are for fun. They can dance, play violin, play sports etc.

     We can put robots in two types. One is industrial robots which are robots have more joints that helps for industry, the other is special robots which the robots do not work for the industry.

     Housework robots: Robots who do housework:
   

(a floor-cleaning robots )

     

     Auto-control robots: Can be re-programmed robots.

     Programing robots: Robots that need to be programed frist. Using for single way.

     

     Numerical control robots: Robots can be taught by language and numbers.

     

     Desaster robots: Help finding survivors in disaster.

Mousetrap

 

     Before I played with both ping pong ball and mouse trap. I played with the mouse trap. I got everything set (put the hold-down bar on the small button.) when I tried to put it on the floor it suddenly starts working and clipped on my finger. it's hurt for a long time but I felt how much power this small trap has.

     The extruding of the spring gives the potential energy to the equipment. Potential energy is the energy that has been stored but not be used. It converts to the kinetic energy when the  equipment is working. Kinetic energy is the energy of motion.

     The way to let the ping Pong ball go further, is get the lever arm which is hammer longer and let the ball get out of the equipment in 45 angles.

      This is a good experiment about newton's first law.

How Challeng Hon Physics is

     Honer physics is not a kind of course that you can still get good grades without preparing before every class and do lots of practice after that. That's means you have to do lots of work to get a good grade. And it's only based on you understand the topic first and know what formulas are standing for. 

     As a foreigner, understanding English is hard for me. Understanding the physics is much more difficult for me. I have to know how the stuff move from which way to which way, it's acceleration or decoration. I even have to know if the ball has a Vo from the words is dropped or throw. 

     Even though the class is challenging but it doesn't mean the class is unavoidable. Being positive and try my best can help me to reach higher and higher.
