Forum User jpieper has made a 3DOF quadruped robot of his own design, using Dongbu DRS-0101 servos. It starts off slowly, but is surprisingly speedy and exceedingly steady. This robot has since been upgraded with a turret and a gimbal, making it Mech Warfare Ready. Check out the thread for more updates! jpieper has a new chassis in the works, and intends to use an integrated odroid daughterboard in the next version. Very cool!
