PELE (Peano-HASEL Electrohydraulic Leg)

PELE (Peano-HASEL Electrohydraulic Leg)

PELE is a musculoskeletal robotic locomotion platform that combines the agility of nature with revolutionary artificial muscle technology. Powered by electrohydraulic artificial muscles, this bio-inspired system demonstrates unprecedented capabilities in robotic locomotion. PELE can perform powerful jumps up to 40% of its leg height, execute agile movements at frequencies over 5 Hz, and adaptively navigate various terrains from sand to rocks using only simple open-loop control.

What sets PELE apart is its remarkable energy efficiency – consuming just 1.2% of the power required by conventional electromagnetic systems during static poses. The system features inherent adaptability through its muscle-like actuators and can detect obstacles through built-in capacitive sensing, allowing it to automatically adjust its motion strategy when encountering challenges.

This technology represents a significant step toward more versatile and energy-efficient robots that can operate effectively in unstructured environments. The combination of PELE’s bio-inspired design, innovative actuator technology, and inherent adaptability opens new possibilities for applications ranging from disaster response to industrial inspection, where robots need to navigate complex terrains while maintaining efficiency and reliability.
