Dodou, D. (author), Van den Berg, M. (author), Van Gennip, J. (author), Breedveld, P. (author), Wieringa, P.A. (author)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...journal article 2008

De Winter, J. (author), Mulder, M. (author), Van Paassen, M.M. (author), Abbink, D.A. (author), Wieringa, P.A. (author)Driver assistance systems that supply force feedback (FF) on the accelerator commonly use relative distance and velocity with respect to the closest lead vehicle in front of the own vehicle. This 1-D feedback might not accurately represent the situation and can cause unwanted step-shaped changes in the FFs during lateral maneuvers. To address...journal article 2008

Dodou, D. (author), Breedveld, P. (author), Wieringa, P.A. (author)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...journal article 2006

Wentink, M. (author), Fischer, H. (author), Dankelman, J. (author), Stassen, L.P.S. (author), Wieringa, P.A. (author)Purpose: To evaluate the effect of perspective distortion of wide-angle lenses in laparoscopes on hand-eye coordination during endoscopic manipulation. Methods: Sixteen subjects repeatedly performed a standardized positioning task in a pelvi-trainer under two conditions. The subjects had no prior experience with endoscopic manipulation. In one...journal article 2002
