Climbing Adhesion This page consolidates work started under a couple of different projects including ClimbingRobot, with the goal of creating patches of synthetic dry adhesive material that are suitable for climbing vertical surfaces. This work has been funded in part by DARPA and by the National Science Foundation under award NIRT (0708367), in collaboration with UCSB.
