Abstract

A formulation of the force acting at the center-point of the end-effector of a manipulator based on a free-body diagram is described. With this formulation, the information about uncertainties at the contact point can be obtained by the force sensor. Therefore, the hard contact adaptive force control is formulated and solved by modifying the end-effector's trajectory and the acting proper force/torque in the joint space. A force control scheme to compensate for an external force and exert a desired force is presented.<>

机械臂硬接触自适应力控制研究
描述了一种基于自由体图的作用于机械臂末端执行器中心点的力的表达式。利用该公式,力传感器可以获得接触点的不确定性信息。为此,提出了硬接触自适应力控制问题,并通过修改末端执行器的运动轨迹和关节空间的作用力/力矩来求解。提出了一种补偿外力并施加所需力的力控制方案。
