Biohybrid robots may need exercise to improve performance

A new study from China shows that robots with lab-grown muscle tissue, known as biohybrid robots, may need exercise like humans to improve strength and agility. This training can double their contraction strength and enhance movement speed. Researchers developed a system that combines electrical and mechanical stimulation to train artificial muscles during growth. This method allows the muscle tissue to perform better, enabling a caterpillar-like robot to move faster than previous models. The study highlights advancements in creating artificial muscle tissue that mimics natural muscle performance. The new system uses electrodes for uniform stimulation and a spring mechanism for mechanical training, allowing real-time adjustments to improve muscle function.
