For this lab, we were given a big robotic kit in order to construct a complete robot. While the process of assembling the robot was fun, what we did after that was more amazing. We were introduced to a software which later we would use to make the robot moves. As the robot moves, we were able to calculate the wheel rotations, how far it traveled, and the velocity of the robot. Even with the computer’s calculation, we would still measure these things ourselves later and compare our result with the computer. I think one of the good thing about this is that you can double check your result using the computer and next time in case we don’t have a computer we would still be able to do the lab. Our measurements compare to the computer were not precise to the milli-unit but it was close enough to the relevant units.The circumference of the wheels was about 0.176m, that means every rotation is equal to 0.176m in distance. The result of the lab is as below:
