Development of a 5-DOF Laparoscopic Assistant Robot

Development of a 5-DOF Laparoscopic Assistant Robot

  Laparoscopic surgery is a new surgery method that has many advantages including a short recovery time and fewer post-operative side effects. Although it has become increasingly popular, there remain problems in applying laparoscopic surgery. Many robotic systems were developed during the last decade to overcome these limitations. In this paper, a 5-DOF laparoscopic assistant robot system is proposed. It takes into account a number of requirements for assisting with laparoscopic surgery. The proposed system is expected to allow various laparoscopic surgeries to be performed with minimal interference with the surgeon. System analysis and experimental results of the system performance are presented.
