In this paper, an hybrid position-position and position-velocity teleoperation control scheme for a generic mobile manipulator is presented and discussed. The mobile manipulator is composed by a mobile platform and a 5 dof arm, and the proposed control scheme allows the simultaneous control of both the devices by means of a single haptic device characterized by an open kinematic chain and not specifically designed for mobile manipulators teleoperation (e.g. a Phantom Omni). The proposed teleoperation controller overcomes the mismatch of the control signals to be sent to the arm (position) and to the mobile platform (velocity) through a proper partition of the master device workspace. Tests have been performed both by simulation and with a real setup. The setup is composed by a 6 dof Phantom Omni haptic device acting as master, and a single-arm Kuka youBot omnidirectional manipulator acting as slave. Experimental results related to a pick and place task, performed on the real setup and involving the motion of both the arm and the platform are reported and commented.

Abstract

In this paper, an hybrid position-position and position-velocity teleoperation control scheme for a generic mobile manipulator is presented and discussed. The mobile manipulator is composed by a mobile platform and a 5 dof arm, and the proposed control scheme allows the simultaneous control of both the devices by means of a single haptic device characterized by an open kinematic chain and not specifically designed for mobile manipulators teleoperation (e.g. a Phantom Omni). The proposed teleoperation controller overcomes the mismatch of the control signals to be sent to the arm (position) and to the mobile platform (velocity) through a proper partition of the master device workspace. Tests have been performed both by simulation and with a real setup. The setup is composed by a 6 dof Phantom Omni haptic device acting as master, and a single-arm Kuka youBot omnidirectional manipulator acting as slave. Experimental results related to a pick and place task, performed on the real setup and involving the motion of both the arm and the platform are reported and commented.
