Abstract: In this paper, an intelligent robot safe mobile gait control method based on strength Pareto evolutionary algorithm is proposed. Determine the tracking error of intelligent robots based on their coordinate positions. Utilising the tracking error of the intelligent robot as a parameter for safety gait control, the strength Pareto evolutionary algorithm is used to optimise the control parameters. Integrating the optimised control parameters with the fuzzy PID controller, the safety gait control of the intelligent robot is achieved. The experimental results show that the discrepancy between the movement trajectory of the intelligent robot controlled by the proposed method and the expected trajectory is extremely small. The maximum collision rate of the intelligent robot is 3.66%, and the minimum response time is 20.36 ms.

Keywords: strength Pareto evolutionary algorithm; intelligent robot; safe mobile; gait control; coordinate positions.
