I enjoyed building my previous two-wheel balancing robot, so I thought I'd move on a little and make a Sonic the Hedgehog ...

Walking robots that move smoothly are tricky to build and usually involve some sort of compliant leg mechanism — a robot limb that can rebound like natural physiology for much better movement ...

A team of scientists has constructed a robot leg that, like its natural model, is very energy efficient. BirdBot benefits from a foot-leg coupling through a network of muscles and tendons that ...

A new soft actuator moves and stiffens like biological muscle. The muscles, or actuators, are constructed from low-cost, ...

The width required by the motors, leg mechanisms, and bearings means the robot is quite wide, to the point that it could get stuck on something that’s outside the camera’s field of view.

ATRIAS’ unusual leg design is central to its agility and efficiency. The four-bar carbon-fiber leg mechanism is very lightweight, softening each footfall instead of sending large jolts to the body.

It’s a “unique krill-inspired robotic swimming appendage” researchers say is the first mechanism allowing for a comprehensive study of what’s known as metachronal propulsion.

A team of scientists at the Max Planck Institute for Intelligent Systems and the University of California, Irvine constructed a robot leg that, like its natural model, is very energy efficient ...
