I can tell you that if you look closely at the Surgibot video, you can sense that the tactile feedback is minimal at best going through so much mechanism.
Also, when you watch the body language of the surgeon with the Surgibot, you realize that the control of motion is coming from the elbows and shoulders. The wrists seem only to be used to rotate the effector. Thumb/Finger motion is only used to grasp. The whole effect seems to be one in which the fine motion of the wrist and fingers that surgeons use is wasted.
Add to that the articulation knob that is somewhere in the middle, along with the camera control.
daVinci and SPORT (I think) allow full wrist motion use with the forearms at rest on a cushion. Surgibot just looks UNCOMFORTABLE, from the stance of the operator to the motion of the handles.
It may be built well, but it just doesn't look ergomonic. The video is a bit bizarre; I suggest they update it with an animal procedure.
In it's defense, it seems a lot of the Surgibot surgeons listed are doing bariatrics. Maybe that is its niche. I wish them luck since I'm sure a lot of people put their hearts into this device.
