Development of a Sword-Fighting Robot Controlled by High-Speed Vision

In this paper, we propose a sword-fighting robot system controlled by a stereo high-speed vision system as an example of human-robot dynamic interaction systems. The developed robot system recognizes both of the positions of a human player and that of the sword grasped by the robot hand. And it detects the moment when the human starts to move by using ChangeFinder which is a method of detecting the turning points. Next it predicts the possible trajectories of the sword of the human player by a
least-squares method from the moment when the attack started. Finally it judges the kinds of the attack and generates an appropriate defensive motion. Experimental results verify the effectiveness of the proposed algorithm.

Paper folding is one of the most difficult tasks for multi-fingered robot hands because paper is deformable and its stiffness distribution is nonuniform. In this study, we aim to achieve dexterous paper folding by extracting some dynamic primitives.
Each primitive uses visual and force information, a physical model of a paper sheet for analyzing its deformation, a machine learning method for predicting its future state. In this paper, we propose a strategy to achieve valley folds of a sheet of paper twice in a row.
In the second fold, a crease line of the first fold disturbs accuracy of the folding. We propose some new manipulation techniques to solve the problem. Finally we show demonstrations of the paper folding achieved with high success rate.
