A virtual environment system with virtual force display and feedback based on master arm

摘要

This paper describes a virtual environment system, which can produce dynamic force simulation during the control of objects in virtual environment. A 5 degrees-of-freedom haptic interface master arm with the capability to generate kinesthetic effect is combined in this system. In this system, the human operator manipulates an object in virtual environment by using the 5-DOF master arm. When virtual manipulator contacting with the virtual object, the contact force can be calculated and shown in the graphic interface. The collision response and deformation of the virtual object, which is usually called haptic rendering, also can be exhibited in graph. The experience presents an approach to improve the operator's immersion and can be used in many telerobot control fields.
