Several passive joints are usually needed in surgical robots to decrease the difficulty in doctors' operating, which can be manually rotated without motor pushing. When stopped at a specified position, passive joints should be locked until operation ends, and keep bearing torques. This paper is aimed to design a locking method used in minimally invasive surgical robot. Firstly choose the locking type based on the technical requirements, and then the dimension can be determined using friction… CONTINUE READING
