基于视觉前馈和视觉反馈的仿人机器人抓取操作

Object Manipulation of a Humanoid Robot Based on Visual Feedforward and Visual Feedback

  • 摘要: 针对仿人机器人执行抓取操作,提出了一种联合使用视觉前馈和视觉反馈的控制策略. 在视觉前馈中利用基于表格的逆运动学算法,简化了逆运动学计算,减少了抓取操作时间. 视觉反馈补偿了弱标定并增加了系统的稳定性. 两种控制算法的联合使用简化了仿人机器人的伸手抓取操作. 实验结果验证了该控制策略的可用性.

     

    Abstract: According to the reach-to-grasp task for a humanoid robot,a method combining visual feedforward and visual feedback is proposed. Reverse kinematics algorithm based on the grid is used in the visual feedforward to facilitate the reach-to-grasp task and reduces the manipulation time. The visual feedback increases the robustness by compensating the weak calibration error. The combination of two control strategies facilitates reach-to-grasp task for a humanoid robot. The robustness of the system is confirmed by experimental results.
