Summary Robots will require some form of proximity sensing in order to perform many delicate exploration, assembly and manipulation tasks. This paper describes a novel articulated tactile probe which can locate and accurately measure the 3-dimensional surface contours of small objects. Although lacking the speed of data acquisition possible with vision and other non-contact sensors, the resulting data is easily processed to give useful information about an object.
