We designed an innovative type of rocker bogie suspension for our robot, which we named BogieBot. The Lego prototype that I personally built was able to climb over all the terrain, even climbing up the cliffs!
Our first scoring design was very ambitious. We tried to make an large arm head with conveyors on a huge arm that would grab and score batons.
Arm head teaser
Unfortunately, the arm head unbalanced the robot and the arm was so heavy it burned out motors. On top of that, it was nearly impossible for it to dispense batons (too much precision required). After our first competition, we tore out the entire arm assembly and designed a new scoring mechanism. It included a fast baton dispenser made mostly out of Lego parts.
It included many other parts too, but I won't spoil it for you. Presenting... The completed BogieBot.
Thanks to technical difficulties, we didn't do well enough to qualify for the national competition, but we earned valuable experience and we made one of the best robots out there.
