There are several important things you should tell your students:
- place angular L-shaped beams at the end of the pivot points of the robot if it’s unstable;
- be careful about the height of the robot so that your filler is below the belt of the previous robot. Otherwise, the balls won’t be able to continue from one robot to another;
- be careful about the height of the filler as sometimes it is too low and the ball cannot be picked up by the conveyor belt;
- add parts on the conveyor belt which will assist the process of picking up balls (the easiest option is long pins).
If you have any problems or the students find it difficult to build their robots, check the instructions below.
