The success of many teleoperation tasks depends heavily on the skills of the operator and his ability to perceive the work environment. Visual feedback, in many cases, is not sufficient e.g. when the image quality of the work environment is low, occlusions occur in the display, or when the task involves contact forces associated with visually unnoticeable small clearances. To compensate for these shortcomings, haptic devices emerge as an alternative to visual feedback, in which touch interaction with the user produces force-feedback. This thesis presents the development and modeling of a haptic interface system of five degrees of freedom for the teleoperation of robot manipulators, focusing on those that work in hazardous or hostile environments for humans. The interface is developed from the coupling of two commercial haptic devices Novint Falcon, with three degrees of freedom each. The system resulting from the coupled devices is modeled as a parallel manipulator capable of providing the operator with 3D force feedback (in three dimensions) and torque feedback in two directions. To demonstrate the effectiveness of the developed haptic system, a virtual environment is implemented with the aid of computer graphics techniques and libraries such as OpenGL, ODE and Chai3D. The kinematic and dynamic models of a serial manipulator Schilling Titan IV, with six degrees of freedom, are implemented in the virtual environment, including its interaction with virtual objects for the evaluation of typical teleoperation tasks. Nonlinear controllers are implemented in the virtual serial manipulator, including computed torque and sliding mode control.
