Researchers at Tohoku University (TU) in Japan found robotic agents using deep reinforcement learning (DRL) algorithms act in a way similar to motor synergy, which enables a body's central nervous system to use a smaller set of variables to control a large group of muscles, simplifying control over coordinated and complex movements.

DRL can help solve complex robotic tasks while reducing manual operations and achieving peak performance.

The researchers used two DRL algorithms, the classical TD3 and the high-performing SAC, on two robotic agents that completed a total of 3 million steps.

Said TU's Mitsuhiro Hayashibe,"After employing deep learning, the robotic agents improved their motor performances while limiting energy consumption by employing motor synergy."
