摘要:

我们试图通过使人类能够控制两个机器人手臂,除了他们的自然手臂使用他们的脚来增强人类的操纵。因此,手可以自由地执行高灵活性的任务,而脚控制的臂执行需要较低灵活性的任务,例如支撑负载。机器人臂通过两个脚接口进行远程操作,脚接口将平移和旋转传输到操纵器的末端执行器。为人提供触觉反馈,以感知接触和负荷变化,并相应地调整脚部压力。现有的脚接口主要用于单脚控制,并且在它们可以控制的运动范围和自由度数量方面受到限制。本文介绍了专门为双足控制制作的脚接口,具有适合双足操作的工作空间,每个工作空间具有五个自由度。本文还提出了一种基于动力学系统调制的阻抗控制的位置-力遥操作轨迹生成控制器。最后,提出了平台的初始验证,由此用户用双脚抓住物体并在物体由脚支撑时产生各种干扰。

英文摘要:

We seek to augment human manipulation by enabling humans to control two robotic arms in addition to their natural arms using their feet. Thereby, the hands are free to perform tasks of high dexterity, while the feet-controlled arms perform tasks requiring lower dexterity, such as supporting a load. The robotic arms are tele-operated through two foot interfaces that transmit translation and rotation to the end effector of the manipulator. Haptic feedback is provided for the human to perceive contact and change in load and to adapt the feet pressure accordingly. Existing foot interfaces have been used primarily for a single foot control and are limited in range of motion and number of degrees of freedom they can control. This paper presents foot-interfaces specifically made for bipedal control, with a workspace suitable for two feet operation and in five degrees of freedom each. This paper also presents a position-force teleoperation controller based on Impedance Control modulated through Dynamical Systems for trajectory generation. Finally, an initial validation of the platform is presented, whereby a user grasps an object with both feet and generates various disturbances while the object is supported by the feet.
