To improve the fast responsiveness and real-time control performance of dVRK surgical robot control system,a real-time control system based on Speedgoat real-time target machine was developed.Through constructing the host machine-the target robot real-time control platform,the UDP Real Time communication model was designed,the host machine and target machine running model were established to realize the real-time control of the robot.The results show that by using the real-time control system,the data acquisition of dVRK robot and the verification of related control algorithm can be accurately completed;the Speedgaot real-time control platform has the advantages of online parameter adjustment,real-time simulation and rapid prototyping of object code,high simulation accuracy,good reliability,which greatly shortens the development cycle of dVRK robot control algorithm.
