In this special robotic platform called PAMELA (short for Pedestrian Accessability and Movement Envrionmental Laboratory), human guinea pigs are subjected to various walkway conditions like inclines, vertical and horizontal gaps, loud noises, wet surface, and other pedestrian hazards.
The University College London research project aims to better understand human reaction to these conditions, in order to make the streets safer for the disabled and everyone else. http://www.cts.ucl.ac.uk/arg/pamela2/index.asp - via Pruned.
