Propulsion-unit and robot provided with such a propulsion-unit

The invention relates to a propulsion-unit provided with a body and comprising at least one element having an external adhesive layer for providing frictional contact with an object's surface along which the unit in use moves, wherein the element is a supporting layer that supports said adhesive layer, and wherein drive means are provided for...

Mucoadhesive films inside the colonic tube: Performance in a three-dimensional world

A self-propelling colonoscopic device moving inside the colonic tube should be able to periodically grip safely to the colonic wall as well as to manipulate the generated friction. The feasibility of achieving high grip and friction manipulation by covering the device with mucoadhesive films is experimentally tested. More precisely, the...

The role of geometry in the friction generated on the colonic surface by mucoadhesive films

One of the main challenges in designing diagnostic devices able to move along the colon is their locomotion method. Generating friction without applying high normal forces is a key requirement in order to eliminate the risk of tissue damage. One possible solution is to generate friction by means of adhesive forces. For this reason, the device...
