Abstract
By a News Reporter-Staff News Editor at Robotics & Machine Learning DailyNews Daily News - New research on Robotics is the subjec t of a report. According to news reporting fromShaanxi, People’s Republic of Ch ina, by NewsRx journalists, research stated, “This paper investigatesthe approx imate optimal coordination for nonlinear uncertain second-order multi-robot syst ems withguaranteed safety (collision avoidance) Through constructing novel loca l error signals, the collision-freecontrol objective is formulated into an coor dination optimization problem for nominal multi-robot systems.Based on approxim ate dynamic programming technique, the optimal value functions and control polic iesare learned by simplified critic-only neural networks (NNs).”The news correspondents obtained a quote from the research from Northwestern Pol ytechnical University,“Then, the approximated optimal controllers are redesigne d using adaptive law to handle the effectsof robots’ uncertain dynamics. It is shown that the NN weights estimation errors are uniformly ultimatelybounded und er proper conditions, and safe coordination of multiple robots can be achieved r egardless ofmodel uncertainties.”
