Haptic Control of the Master Hand Controller for a Microsurgical Telerobot System
نویسندگان
چکیده
A microsurgical telerobot system has been developed based on the results of the operation task analysis. The telerobot system is composed of a 6-dof parallel micromanipulator attached to the macro-motion industrial robot, and a 6-dof force-reflecting haptic master device. The master device is using five-bar parallel mechanisms driven by harmonic DC servomotors. The proposed 6-dof master hand controller has nonlinear and coupled dynamics, and friction. Since the disturbance force owing to ji-iction, gravity and coupled inertia can distort the operator's perception, the disturbance observer has been introduced in the operational space and implemented to the microsurgery master hand controller.

In this study, a force reflection control structure is developed for the surgery training haptic system. In the surgery training haptic system, the surgical operation is cooperatively performed by a trainer and a trainee. The participation of each surgeon in the operation is established through their own haptic consoles. Although the operation is primarily performed by the trainee, the trainer ...
متن کاملHaptic feedback of kinematic conditioning for telerobotic applications
Kinematic conditioning of robot manipulators is the problem where small motions in Cartesian space cause excessive joint velocities. This problem is signi cant in teleoperation. Haptic feedback provides the bi-directional ow of information which allows the operator to control the telerobot interactively. Haptic feedback of kinematic conditioning is proposed as a new approach to achieve better p...
متن کاملDesign and Control of a Force-reflecting Haptic Interface for Teleoperational Grasping
In this paper the design of a multi-finger force-reflecting haptic interface device for teleoperational grasping is introduced. The haptic interface or “master” controller device is worn on the human operator’s hand and measured human finger positions are used to control the finger positions of a remote grasping manipulator or “slave” device. The slave may be a physical robotic grasping manipul...

There are two significant goals in teleoperation systems: Stability and performance. This paper introduces an LMI-based robust control method for bilateral transparent teleoperation systems in presence of model mismatch. The uncertainties in time delay in communication channel, task environment and model parameters of master-slave systems is called model mismatch. The time delay in communicatio...
