FMEA‐Based Coverage‐Path‐Planning Strategy for Floor‐Cleaning Robots
Advanced Intelligent Systems, Volume 5, Issue 11, November 2023., 2023 Robots face challenges in environments with hazardous components, affecting their performance. A novel coverage path‐planning method is proposed that trades‐off between coverage and robot safety in environments with predefined hazard maps. Failure mode and effect analysis (FMEA) is utilized to classify hazards and ensure safety during planning.

Velocity‐free formation control for omnidirectional mobile robots with input saturation
IET Control Theory &Applications, Volume 17, Issue 10, Page 1265-1282, July 2023., 2023 This paper proposes a formation control scheme for the leader‐follower omnidirectional mobile robots. By means of the designed velocity observer based on a novel state transformation, the finite‐time command filtering strategy and the anti‐saturation module, the closed‐loop system can ensure that all signals are uniformly bounded, even subject to the ...

The Path Planning and Location Method of Inspection Robot in a Large Storage Tank Bottom
Computational Intelligence and Neuroscience, Volume 2023, Issue 1, 2023., 2023 With the development of robot technology, inspection robots have been applied to the defect detection of large tanks. However, the existing path planning algorithm of the tank bottom detection robot is easy to fall into the local minimum, and the path is not smooth. Besides, the positioning of the tank bottom detection robot is not accurate.

Proximal policy optimization based dynamic path planning algorithm for mobile robots
Electronics Letters, Volume 58, Issue 1, Page 13-15, January 2022., 2022 Abstract For the scenario where the overall layout is known and the obstacle distribution information is unknown, a dynamic path planning algorithm combining the A* algorithm and the proximal policy optimization (PPO) algorithm is proposed. Simulation experiments show that in all six test environments, the proposed algorithm finds paths that are on ...
