While the components of the MiroSurge system are shown to fulfil the rigid design requirements for robotic telesurgery with force feedback, the system remains versatile, which is supposed to be a key issue for the further development and optimisation.
Abstract-This video presents the in-house developed DLR MiroSurge robotic system for surgery. As shown, the system is suitable for both minimally invasive and open surgery. Essential part of the system is the MIRO robot: The soft robotics feature enables intuitive interaction with the robot. In the presented minimally invasive robotic setup three MIROs guide an endoscopic stereo camera and two endoscopic instruments with force feedback sensors. The master console for teleoperation consists of an autostereoscopic monitor and force reflecting input devices for both hands. Versatility is shown with two additional applications: For assistance in manual minimally invasive surgery a MIRO robot automatically guides the endoscope such that the surgical instrument is always in view. In a biopsy application the MIRO robot is positioning the needle with navigation system support.
Abstract-This paper introduces the planning and control software of a teleoperation system for research in minimally invasive robotic surgery. It addresses the problem of how to organize a complex system with 41 degrees of freedom as a flexible configurable platform. Robot setup planning, force feedback control and nullspace handling with three robotic arms are considered. The planning software is separated into sequentially executed planning and registration procedures. An optimal setup is first planned in virtual reality and then adapted to variations in the operating room. The real time control system is structured in hierarchical layers. Functions are arranged in the layers with respect to their domain and maximum response time. The design is flexible and expandable while performance is maintained. Structure, functionality and implementation of planning and control are described. The prototypic robotic system provides intuitive bimanual bilateral teleoperation within the planned working space.
