摘要:

这项工作使用矢量场不等式(VFI),以防止机器人的自碰撞和碰撞的工作空间。与以前的方法不同,该方法适用于速度和扭矩驱动的机器人。我们提出了一个新的距离函数及其相应的雅可比矩阵,以产生一个VFI来限制两个Plücker线之间的角度。这种新的VFI用于防止不期望的末端执行器方向和违反关节限制。所提出的方法进行评估,在一个现实的模拟和一个真正的人形机器人,显示所有的约束,而机器人执行操作任务。

英文摘要:

This work uses vector field inequalities (VFI) to prevent robot self-collisions and collisions with the workspace. Differently from previous approaches, the method is suitable for both velocity and torque-actuated robots. We propose a new distance function and its corresponding Jacobian in order to generate a VFI to limit the angle between two Plücker lines. This new VFI is used to prevent both undesired end-effector orientations and violation of joints limits. The proposed method is evaluated in a realistic simulation and on a real humanoid robot, showing that all constraints are respected while the robot performs a manipulation task.
