Robot teleoperation is defined as using a remote control to perform tasks requiring on-site operation while the operator is located far from the robot's on-site operable environment. COVID-19, an acute respiratory syndrome, has led to a rapid increase in people's demand for robot teleoperation technology. By applying motion information from the human motion to a slave robot, the current study developed a teleoperation system to realize some medical processes remotely during COVID-19. This system has great potential to advance teleoperation technology during and after the pandemic. Our results show that the motion mapping algorithm possesses more accuracy and stability compared to the traditional kinematic method.
