For my group, the robotics activity had some difficulties. When we had first tried making the robot, we did not have all of the necessary parts that we had needed. We discovered a way to fix this problem, until we found this did not allow the robot to do what it was supposed to do. After we learned we had some errors within our robot, we joined with another group so that we had a properly working robot that was able to move like we needed.
The program on the computer, for me personally, was difficult to navigate. Once we had figured it out, programing the robot to move how we wanted to was interesting. We learned that the degree that the wheel rotated is related tot he turns of the wheels because it determines how far the robot will move. After playing around with different tricks it could do, we had difficulties when we unplugged it from the computer. We had it set on too fast of a speed, but when we had tried to re-program it, it just kept staying at the same speed.
Finally the next day, when we were checking how far it could go in so many seconds, it was able to work. On our first try, we had it set on a speed of 25, and in one second it traveled 29 centimeters. On the second try, we kept it on a speed of 25, and in two seconds it traveled 32 centimeters. This did not seem like it made a huge difference, but it does make sense. A small discrepancy that we realized could have happened, is that it was possible that the line of the tire was not perfectly matched up with the line of the centimeter, so our reading could not be entirely accurate.
