Summary:
Japanese researchers have unveiled a groundbreaking two-legged biohybrid robot that combines muscle tissues and artificial materials, drawing inspiration from human gait. Published in the journal Matter, the innovative design allows the robot to walk, pivot, and make fine-tuned turning motions. The researchers aim to enhance the robot’s speed and agility by integrating electrodes and plan to add joints and thicker muscle tissues for more sophisticated movements in the future. 
Key Concepts:
- Researchers from the University of Tokyo create a two-legged biohybrid robot inspired by human gait.
- Muscle tissues and artificial materials are combined to achieve efficient and silent movements.
- The robot mimics human walking and pivoting motions, showcasing fine-tuned turning capabilities.
- Silicone rubber forms the robot’s flexible skeleton, with lab-grown skeletal muscle tissues attached to each leg.
- Electric stimulation of muscle tissues propels leg movements, enabling walking, stopping, and turning.
- The current manual electrode movement is expected to be integrated into the robot for increased speed.
- Future plans include adding joints, thicker muscle tissues, and a nutrient supply system for enhanced capabilities.
- The project receives support from JST-Mirai Program, JST Fusion Oriented Research for disruptive Science and Technology, and the Japan Society for the Promotion of Science.
