摘要:

广义手操作一直是机器人技术中一个尚未解决的难题。作为实现这一宏伟目标的一小步,我们演示了如何设计和学习一个简单的自适应控制器,仅使用指尖实现在手对象旋转。该控制器完全在模拟中仅对圆柱形物体进行训练,然后-无需任何微调-可以直接部署到真实的机器人手上,以旋转z轴上具有不同大小,形状和重量的数十个物体。这是通过控制器仅使用本体感受历史来快速在线适应对象属性来实现的。此外,通过强化学习训练控制策略,自然和稳定的手指步态自动出现。代码和更多视频可在https://haozhi.io/hora上获得

英文摘要:

Generalized in-hand manipulation has long been an unsolved challenge of robotics. As a small step towards this grand goal, we demonstrate how to design and learn a simple adaptive controller to achieve in-hand object rotation using only fingertips. The controller is trained entirely in simulation on only cylindrical objects, which then - without any fine-tuning - can be directly deployed to a real robot hand to rotate dozens of objects with diverse sizes, shapes, and weights over the z-axis. This is achieved via rapid online adaptation of the controller to the object properties using only proprioception history. Furthermore, natural and stable finger gaits automatically emerge from training the control policy via reinforcement learning. Code and more videos are available at https://haozhi.io/hora
