Haptic Endoscopic Surgery Robot Utilizing FPGA

In late years, techniques and instruments for endoscopic surgery have been developed. The endoscopic surgery is a minimally invasive surgery, hence the quality of life (QOL) of patients can be improved. The endoscopic surgery still has, however, great difficulty for surgeons despite the development of the techniques and the instruments. To solve the problem, it has been studied to apply the technology of robotics to the endoscopic surgery. In this paper, a multi-degree of freedom haptic endoscopic surgery robot is developed aiming at the practical application of applying the robotics technology to the endoscopic surgery. The developed robot is a master-slave type robot, and a bilateral control system based on acceleration control is implemented. To achieve a short sampling period of the control calculation, FPGAs are utilized as processors. The validity of the developed robot is verified through some experimental results.
