Technology and Method Optimization for Foot-Ground Contact Force Detection in Wheel-Legged Robots.

Wheel-legged robots combine the advantages of both wheeled robots and traditional quadruped robots, enhancing terrain adaptability but posing higher demands on the perception of foot-ground contact forces. However, existing approaches still suffer from limited accuracy in estimating contact positions and three-dimensional contact forces when dealing with flexible tire-ground interactions. To address this challenge, this study proposes a foot-ground contact state detection technique and optimization method based on multi-sensor fusion and intelligent modeling for wheel-legged robots.
