Here's a robot video that I found interesting:
T8 is a wirelessly controlled bio-inspired octopod robot made with high resolution 3D printed parts. It uses a total of 26 motors: 3 in each leg and 2 in the abdomen. It is powered by the Bigfoot™ Inverse Kinematics Engine which performs all of the necessary calculations for smoothly controlling the motions of the robot in real time.
Also check out a Robugtix hexapod based on the Bigfoot™ Inverse Kinematics Engine:
