Researchers have developed DC-Ada, a novel method for adapting decentralized multi-robot systems to heterogeneous sensing capabilities. This approach keeps a pre-trained shared policy fixed and instead modifies compact per-robot observation transformations. DC-Ada is gradient-free and requires minimal communication, utilizing budgeted random search with short rollouts. Evaluations in simulated warehouse logistics, search and rescue, and collaborative mapping scenarios demonstrated that DC-Ada can significantly improve performance in heterogeneous environments, particularly for coverage-based mapping tasks, without needing policy fine-tuning.
