Developed by the Delft University of Technology, Mike is a 2D robot that is pneumatically activated biped and has knees. The prototype makes use of McKibben muscles to offer minimal actuation for walking on a flat floor.
The JSK Laboratories and the University of Tokyo developed a whole body tendon robot called the Rabbit. It has multi-joint flexible spine and can do simple gymnastic movements.
Designed by Jerry Pratt and developed by an ensemble cast at MIT, the Spring Flamingo resembles its avian namesake but has human-like movement due to bent-forward knees.
