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

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.
