Title Modeling and Expression of Virtual Feedback Force towards Teleoperation Robot
Abstract
Teleoperation technology can be used to instruct robots work,where human beings can not enter,for instance, the hazardous mine and the high-temperature environments. For improving the level of teleoperation system, a new technology called telepresence technology tightly related to the interaction technology has been put forward. According to the feedback information of teleoperation system, the operator can feel the interaction between the robot and the surrounding objects or the environment directly, thus improving the quality and speed of the teleoperation work.
The thesis summarizes the character of the telepresence technology and its research development, builds the geometry modeling of the environment and reemerges the real situation.3D model of all parts of the robot has been built and assembled. The kinematics of the mechanical arm was analyzed according to the structural characteristic and the kinematics constraints. Thus, building the positive motion model and inverse kinematic model to control the movement of the robot arm in real time. The force can be calculated by setting the micro displacement. The virtual environment with good man-machine interactive features is designed by applying C++ and OpenGL language.
