Optimization of collaborative robot motion trajectory based on energy consumption model

To enhance the dynamic performance and reduce energy consumption of collaborative robots, a motion trajectory optimization method based on an energy consumption model is proposed. By establishing a dynamic model of the entire collaborative robot and analyzing its energy consumption characteristics during operation, a joint energy consumption integrated model and a complete machine energy consumption model are constructed. A trajectory optimization method for collaborative robots is proposed, with energy consumption as the optimization objective and time and speed as the optimization variables. This approach optimizes the overall energy consumption of the collaborative robot, resulting in a reduction in energy consumption. Experimental results demonstrate that the optimized robot lowers energy consumption, and the optimal combination of time and speed reduces energy consumption by approximately 4% and 2%, respectively, compared to pre-optimization levels. These experiments validate the feasibility of the method and provide valuable insights for reducing robot energy consumption.
