Benefit

Today we are seeing more of an emergence of legged robots, and especially bipedal robot technology. These robots have the possibility to traverse difficult terrain that wheeled or tracked robots could not. However, current bipedal robots are large and typically designed to need a large amount of sensing, actuation, and control. Some of the more elegant and modern bipedal robots that use torque control still need to be powered and command actuators to stand upright.

This robot technology is a quasi-passive, three-dimensional, bipedal walker device. The robot weighs a magnitude less than other previous bipedal robots inspired by passive walkers. The robot had a much smaller leg length, in turn, making the robot slower than other robots. However, when scaled for leg lengths per second traveled, this robot is near the same speed as others. With only 2 actuated degrees of freedom and no feedback from sensors to the environment, this robot is simpler than previous state of the art bipedal robots inspired by passive walking.
