Passive teleoperation of mobile robot with input-output linearization and dynamic extension
2014
This paper describes a proposal for architecture of teleoperation of a mobile robot Quanser Qbot. The robot is telemanipulated by a haptic device Sensable Phantom Omni. For this task, a basic model of the mobile robot is input-output linearized with dynamic extension and it is controlled safely in a teleoperation task in passivity framework. The advantages of the proposal are: (i) the I/O linearization changes the Qbot kinematics from polar to cartesian, facilitating the matching with the omni workspace and (ii) the stability of the system is ensured from the passivity framework adopted.
