Humanoid robot motion generation for nailing task

In order to exert a large force on the environment, it is effective to apply impulsive force. We describe the motions that perform tasks by applying impulsive force as “impact motion.” In this research, a nailing task is taken as an example of impact motion. This paper proposes a way to generate impact motions for humanoid robots to exert a large force and the feedback control method for driving a nail robustly. In order to validate the proposed scheme, experiments are carried out using life-sized humanoid robot HRP-2. The motion for nailing task generated by the proposed method is compared with the motion designed heuristically by a human. The driving depth is clearly increased by the proposed method.
