IBIS pneumatic keyhole surgery robot

“A feature of the slave robot is, it’s powered entirely by air. Nearly all conventional robots are electrically powered, but by driving this robot pneumatically, we’ve made it possible to gently absorb the force when the robot touches something. The force on the tip of the robot is estimated from the air pressure data, and that information is sent to the surgeon’s master robot. So, it can be fed back to the surgeon’s hand. Alternatively, a large force can be produced by a very lightweight, compact unit. An advantage of this phy4system is, the robot overall can be made extremely compact.”


“Here, the user is operating the master robot. This demonstration enables you to experience, for example, how you can feel the reaction force when you pull the rubber band.”

“Of course, you can eliminate shaking of the hand, change the motion ratio, and change the force feedback factor. So, depending on the medical staff and the situation, the parameters can be varied, to make the system easier to use on the spot.”
