I had enough robots for my students to work in 4 groups of 3. I wanted to focus on the sensors and remote controlling/programming. I set forth various challenges. One was an obstacle course the robot had to navigate. Then the head to head balance test. The finally sensors, the roaming test. The obstacle course tested their programming skills for a known path. The balance test was remote “fighting” between robots to see who could remain standing. This was to test the structure/stability of the robot. The last test, the students had to use sensors and programming to start the robot in the floor, it had to roam the room, if it ran into an obstacle it had to be able to get out of the situation.
