摘要:

在类人机器人的多目标全身控制器中不处理撞击感知任务(即目的撞击)。这导致了这样一个事实,即人形机器人通常以接近零的速度操作以与外部环境交互。我们明确调查的传播的影响引起的速度和扭矩跳跃沿结构联动,并提出了一组约束,总是满足硬件限制,维持已经建立的接触和稳定性措施,即零力矩点条件。在不假设碰撞位置或时间的情况下,我们提出的控制器使人形机器人能够产生非零的接触速度,而不会破坏已建立的接触或跌倒。我们的方法的新颖之处在于建立在现有的连续动态全身多目标控制器,而不需要重置地图或混合控制。

英文摘要:

Impact-aware tasks (i.e. on purpose impacts) are not handled in multi-objective whole body controllers of hu-manoid robots. This leads to the fact that a humanoid robot typically operates at near-zero velocity to interact with the external environment. We explicitly investigate the propagation of the impact-induced velocity and torque jumps along the structure linkage and propose a set of constraints that always satisfy the hardware limits, sustain already established contacts and the stability measure, i.e. the zero moment point condition. Without assumptions on the impact location or timing, our proposed controller enables humanoid robots to generate non-zero contact velocity without breaking the established contacts or falling. The novelty of our approach lies in building on existing continuous dynamics whole body multi-objective controller without the need of reset-maps or hybrid control.
