仮想非駆動関節を用いたマニピュレータによる可搬重量を超えた物体のハンドリング (第1報,概念と仮想非駆動関節の実現方法)

Abstract

The load capacity of a manipulator depends on a load capacity of a low output joint or load capacities of some low output joints of the manipulator. Even if a manipulator could not handle an object because of its load capacity, some of its joints still have enough capabilities for handling of the object. In this paper, we propose a method to handle an object using available joints of the manipulator by introducing virtually unactuated joints. The virtually unactuated joints are controlled so that no load will be applied to the joints. Experiments illustrate the validity of the method proposed in this paper.
