Necessity Design a tool to perform remote handling

tests with force feedback.

Function Remotely control a manipulator with a

haptic interface.

Justification

The problem of designing a system that combines the virtues of the teleoperation and haptic technologies gives rise to this project, because it is really difficult to find systems or projects that inflect this robotic areas. Hereby we propose the development of a system that allows us to emulate opposition forces that occur in an enviroment out of reach.
