GRA

GRA stands for Growing Robotic Arm. While it did not really grow, it could make its self taller, longer, or shorter if it needed to. The arm was on top of the main body. There are 2 sets of 2 motors for each of the joints, I had to do this to have enough power. I never got pass my test phase using a remote that I made. GRA was involved in an accident that damaged it enough that I could not rebuild it with out taking the whole thing apart.
