Description

The Rasso robot is a biomimetic robot expected to be used in place of standard laproscopic surgery. Being inserted through a 3-4 cm incision, the robot is designed to navigate along the top of the abdominal wall. This is made possible due to the stomach being inflated by a gas throughout the surgery. The Robot, having pads attached to its legs that mimic a gecko's limbs, allow for the robot to adhere itself upside down to the wall of the inflated stomach. The micro-structure of this material allows for adhesion to a wet surface just as a gecko's would. Utilizing a peeling motion to detract the legs, the robot is capable of moving across the surface without dropping towards the surgical area. It is hoped that eventually laproscopic tools can be attached to the robot that will allow this surgery to be performed remotely. My contribution specifically involves the introduction of a new kinematic design that allows for improved movement along the abdominal wall. Within that redesign I also am working towards improving the necessary peeling motion of the gecko-like material so as to minimize reactionary forces acting on the robot.
