Researchers at the Tokyo Institute of Technology have developed the IBIS robot system for keyhole surgery. The system uses a pneumatic robot driving system to offset the impact when the robot touches an object. The IBIS system absorbs the force of impact and the feedback is sent back to the surgeon’s hand. The unit is more compact and lightweight than the more expensive da Vinci surgical system and can be adjusted to fit each individual surgeon.
