Robot Legs 6-Feet Tall Hybrid Leg Mechanism
Humanoid robots are nothing new, but what about a pair of massive robot legs that stand 6-feet tall? Researchers Kevin G Gim and Joohyung Kim from KIMLAB have created just that. Simply put, it’s a large-scale biped robot that uses Hybrid Leg, which is a a 6 degrees of freedom (DOF) serial-parallel mechanism. This lightweight, high payload structure was designed for a large workspace and could one day be used in factories.

The researchers actually set out to make a biped robot taller than an average human, and by applying the Hybrid mechanism and design optimization, they ended up with a creation that stood 6-feet (1.84-meters) tall while weighing just 64 lb (29.05 kg). Despite its size, these legs are actuated with servo motors found in smaller humanoid robots. A frightening sight would definitely be Sophia, the AI robot, with these legs.

Through multi-body dynamics simulations, the proposed robot design and its performance are verified. In addition, the preliminary performance evaluations for the robot hardware are conducted for a squat experiment and in-place walking experiment,” said the researchers.
