The new leg uses electro-hydraulic actuators called HASELs, which work on the principle of electrostatic attraction. These oil-filled actuators move by changing the voltage between the electrodes, allowing them to mimic the movement of human muscles.
Compared to traditional motorized legs, the new model is much more efficient: it does not generate excessive heat and does not require additional cooling. Unlike traditional electric motorized systems, which usually lose energy as heat, the new leg maintains a constant temperature thanks to its electrostatic design.
Scientists also noted that the robotic leg has a high degree of adaptability, which is critical for soft robotics. This allows it to effectively deal with uneven surfaces and perform high jumps. In the future, this technology may find application in rescue operations and other areas requiring high mobility of robots.
