Publication Summary and Abstract

Fox C, Evans M, Lepora N, Pearson M, Hamm A and Prescott T (2011), Crunchbot: A mobile whiskered robot platform. , Springer LNCS proceedings of Towards Autonomous robotic systems (TAROS).

CrunchBot is a robot platform for developing models of tactile perception and navigation. We present the architecture of CrunchBot, and show why tactile navigation is difficult. We give novel real-time performance results from components of a tactile navigation system and a description of how they may be integrated at a systems level. Components include floor surface classification, radial distance estimation and navigation. We show how tactile-only navigation differs fundamentally from navigation tasks using vision or laser sensors, in that the assumptions about the data preclude standard algorithms (such as extended Kalman Filters) and require brute-force methods.
