As if I don't have enough robot kits, they just came out with a new one that I had to try called
Tetrix Prime. You run this little robot with a remote control joystick. It can maneuver really easily and make very sharp turns and it moves much faster than the smaller LEGO robots. I love the little gripper. I'm not quite skilled enough to pick up a ball and put it in the cup, but I'm working on it. Oh, and this is serious "work" for me. I'm teaching 3 new camps this summer with this little robot. Whoopee!
