Series-Wheeled Legged Control System Design and Implementation

Abstract

This post describes the design and implementation of a 3-DOF wheeled-leg robot chassis, integrating wheeled and legged movement for enhanced mobility.

i System Design

  • Designed a 3-DOF wheeled-leg robot chassis, integrating wheeled locomotion with legged movement to enhance mobility and adaptability across diverse terrains.

ii Control Algorithm

  • Implemented a high-stability control algorithm leveraging a Kalman fusion observer for real-time state estimation and sensor data integration.
  • Adopted a hybrid control approach combining Linear Quadratic Regulator (LQR) for optimal trajectory control and Proportional-Integral-Derivative (PID) controllers for precise motion adjustments.

iii Embedded System Development

  • Developed an embedded system to execute the control algorithm, enabling seamless coordination between the robot’s wheels and legs.

iv Experimental Validation

  • Conducted tests to validate the stability, precision, and adaptability of the control system under various operational scenarios, ensuring optimal performance across complex environments.
