A team from Tsinghua University and Beihang University has developed a programmable artificial musculoskeletal actuator inspired by biological systems. This innovation allows for dynamic adjustments in morphology and stiffness, enabling robots to switch between different forms and functions. Two prototypes have been created: one weighing 1.8 grams that can alternate between quadrupedal and humanoid forms, and another mimicking a sugar glider, weighing 6.4 grams, capable of crawling, carrying objects, and gliding.
This development is significant as it addresses the complexities of robotic design, particularly in miniaturized systems where space and power are limited. The new actuator system utilizes liquid crystal elastomers and shape memory polymers to achieve shape retention and dynamic control. The ability to independently adjust the stiffness and morphology of the robotic muscles enhances performance versatility, allowing robots to adapt to various tasks.
Future developments to watch include potential applications of this technology in diverse fields such as search and rescue, exploration, and personal assistance. The research team has published their findings in the journal Science Advances, highlighting the importance of this work in advancing robotic capabilities and functionality.
