无人机无碰撞遥操作变尺度速率控制

Variable-Scaling Rate Control for Collision-Free Teleoperation of an Unmanned Aerial Vehicle

Boston University(波士顿大学)

Dawei Zhang, Rebecca P. Khurshid

摘要:

我们建议,自动调整率控制遥操作的比例因子,可以使人类操作员更好地控制远程机器人的运动。在本文中,我们提出了四个新的可变缩放率控制方法,调整的比例因子取决于用户的输入命令的状态和/或机器人与其环境之间的碰撞的风险。取决于碰撞风险的方法被设计为通过在操作员发出将导致机器人与其环境之间的碰撞的命令时将比例因子设置为零来保证避免碰撞。一个受试者内的用户进行了研究,以确定四个新设计的速率控制方法和传统的固定规模的速率控制方法对一个人的能力,在一个模拟的二维环境中完成导航任务的影响。研究结果表明,设计良好的变尺度速率控制可以保证无碰撞的遥操作,而不降低任务效率。

英文摘要:

We propose that automatically adjusting the scale factor in rate-control teleoperation could enable a human operator to better control the motion of a remote robot. In this paper, we present four new variable-scaling rate-control methods that adjust the scale factor depending on the state of the user's input commands and/or the risk of a collision between the robot and its environment. Methods that depend on the risk of a collision are designed to guarantee collision avoidance by setting the scale factor to be zero if the operator issues a command that would result in a collision between the robot and its environment. A within-subject user study was conducted to determine the effects of the four newly designed rate-control methods and a traditional fixed-scale rate-control method on a person's ability to complete a navigation task in a simulated two-dimensional environment. The results of this study indicate that well-designed variable-scale rate control can guarantee collision-free teleoperation without reducing task efficiency.
