Geometric deep learning enables local sensing for robot reconfiguration

Researchers have demonstrated that local sensing is sufficient for effective global reconfiguration of homogeneous pivoting cube modular robots. A neural network, trained using reinforcement learning, controls each cube and only accesses information from its immediate neighbors. The study found that while localized versions of the network can achieve reconfiguration, faster results are obtained when cubes have more information about the entire ensemble. Including grid symmetries in the neural network architecture offered minor benefits during training but allowed for smaller model sizes. AI

IMPACT This research could lead to more efficient and autonomous robotic systems capable of complex coordinated movements with limited communication.
