Legged robots have the potential to become vital in maintenance, home support, and exploration scenarios. In order to interact with and manipulate their environments, most legged robots are equipped with a dedicated robot arm, which means additional mass and mechanical complexity compared to standard legged robots. In this work, we explore pedipulation - using the legs of a legged robot for manipulation. By training a reinforcement learning policy that tracks position targets for one foot, we enable a dedicated pedipulation controller that is robust to disturbances, has a large workspace through whole-body behaviors, and can reach far-away targets with gait emergence, enabling loco-pedipulation. By deploying our controller on a quadrupedal robot using teleoperation, we demonstrate various real-world tasks such as door opening, sample collection, and pushing obstacles. We demonstrate load carrying of more than 2.0 kg at the foot. Additionally, the controller is robust to interaction forces at the foot, disturbances at the base, and slippery contact surfaces.

通过训练具有位置目标跟踪功能的强化学习策略，我们实现了利用四足机器人的腿进行操作的专用控制器，该控制器对干扰具有鲁棒性，在全身行为中具有大的工作空间，并且能够通过步态出现实现远距离目标达成，实现了步态操作。通过在四足机器人上使用遥操作部署我们的控制器，我们展示了开门、收集样品和推动障碍物等各种现实任务。我们还展示了在足上承载超过2.0千克的负载，此外，该控制器对足部的相互作用力、基座的干扰和滑动接触表面具有鲁棒性。
