摘要: 提出了一种融合视觉与触觉、轨迹规划以及步态实时调整的四足机器人越障方法,旨在应对机器人在崎岖不平地形中遇到不同障碍物的情境。该方法借助跨平台计算机视觉库(Open Source Computer Vision Library,OpenCV)技术对障碍物进行实时识别处理,使机器人能够根据不同障碍物特征选择适当的步态前进并越障。在步态规划过程中,足端轨迹的生成过程受位置、速度、加速度及逆向运动学等多重条件影响,系统结合实时获取的视觉、触觉传感数据,并通过正向运动学计算,精确定位足端轨迹位置,从而制定越障策略。通过在Webots平台上的仿真测试及四足机器人实验验证,结果表明:该方法具备良好的适应性与稳定性。

Abstract: A quadruped robot obstacle navigation method is proposed that integrates vision and tactile sensing,trajectory planning,and real-time gait adjustment. This method is designed to address scenarios where the robot encounters various obstacles on uneven terrain. This method leverages OpenCV technology to identify and process obstacles in real time,enabling the robot to select an appropriate gait based on the characteristics of each obstacle. During gait planning,the generation of the foot trajectory is influenced by multiple factors,including position,velocity,acceleration,and inverse kinematics. The system combines real-time visual and tactile sensor data with forward kinematics to infer foot position,thereby formulating an obstacle navigation strategy. Simulation tests on the Webots platform and experiments with a quadruped robot have demonstrated the method′s adaptability and stability.

Key words: vision, touch, quadruped robot, obstacle-crossing, OpenCV technology, Webots platform
