3d Printed Quadruped

Primary image

What does it do?

Obstacle avoidance via ping, hand tracking (eventually)

Still lots to do, but I finally got this guy printed and assembled. He has 3DOF per leg using cheap 9g servos :( I'm using Inverse kinematics for his movement. I just started programming him and got the IK working for one leg. The ping((( is just stuck in the mega2560 for now. I'll be adding a tilt/pan head when I get more servos, and the wiring needs some cleaning up :p I just found out about LMR last week and so far it's awesome! Hopefully by the end of next weekend I'll have some walk sequence video to show off.
