Research on Human-Computer Interactive Virtual Robot Based on Force Feedback Device

Virtual robot simulation control is the key technology of the virtual surgery system. A new human-computer interactive motion control algorithm was proposed by researching and analyzing the issues that robot motion simulation in the virtual environment was not realistic and not intuitive. By using this algorithm, the force feedback device Omega.7 could control the position and attitude of the virtual robots respectively, which made the virtual simulation more realistic and reliable. First, a virtual robot motion control simulation platform was set up. Second, the D-H parameter method was used to analyzing and studying the kinematics of the virtual robot. On the basis of this, the corresponding relationship between the behavior information of the Omega.7 and the motion information of the robot in the virtual environment was established. Finally, by using of the Omega.7, the virtual robot motion was controlled, and the virtual robot fully mapped the position and attitude of the Omega.7, the human-computer interaction was achieved. The simulation results showed that the motion control method could realize the real-time and effective motion control of the virtual robot by Omega.7, which was more realistic and reliable than the traditional control method, and visually gave the operator a sense of immersion and reality sense, so that the operator had an immersive feel.
