This year I am trying to make the basic robotics class a little less....basic. So among other things I am asking each student to design and 3D print one part for their little robot. Here are a few examples.
Most of the above items are hubs, little spacers that mate servos to wheels. The green ones are for a turtle themed robot. The little triangular "Doom" flag is an interesting choice. This student decided to spend some time working on a little flag before actually building anything else!
I'm not sure how much fear the name "Sheep" will inspire in its foes but, hey, I let the kids build whatever they want.
