New Robot Leg Uses Oil-Filled 'Muscles' for Superior Performance

Researchers at ETH Zurich and Max Planck Institute develop energy-efficient, adaptive robotic limb powered by electrohydraulic actuators.

The robotic leg mimics animal muscles using oil-filled plastic bags and electrostatic actuators.
This design significantly reduces energy consumption and excess heat compared to conventional motor-driven legs.
The robotic limb can perform high jumps and adapt to varied terrain without complex sensors.
The technology marks a shift from traditional motor-driven systems to more biologically inspired designs.
Future developments aim to untether the leg for use in advanced robotic applications.
