This paper presents the mathematical and structural model, simulation and computed torque control of the LapBot robot, developed by the Group of Investigation of Industrial Automatics, of the Universidad del Cauca, Colombia. First, a summary of the principal surgery assistant robots of the world is presented, and how they solve the problem of passing through the incision into the abdominal cavity. Based on this, the conditions that must be fulfilled by the robots of this type is exposed, and from these conditions the LapBot robot is designed. Its kinematics and dynamics model is shown, as well as the mathematical spatial restriction that incision represents. A control strategy based on the model (computed torque control) is implemented. Several trajectories defined in a plane and in a three dimensions space are used to validate the model and the control.
