Geckos, cockroaches, and hordes of other climbing animals are able to ascend vertical surfaces with staggering speed and agility that seems to match their capabilities on level ground. Research conducted at Berkeley’s Poly-PEDAL Lab by Dan Goldman examined the forces which geckos and cockroaches generate while climbing. It is this work that has informed and inspired the design of our climber.
DynoClimber was built to emulate the force patterns exhibited by climbing animals in the hopes of generating rapid, stable vertical locomotion. The robot is purpose built in its current incarnation to decouple the dynamics of climbing rapidly from the climber’s attachment to the wall; it climbs a carpeted vertical surface, employing aluminum claws to grasp the surface. This goal differs from the more utilitarian RiSE robot, which climbs a variety of different surfaces, albeit at a much slower pace.
Thus far, DynoClimber has achieved strikingly rapid dynamic climbing, achieving velocities of 66cm/s (1.5 bodylengths/second) up a vertical surface. Ongoing work by Goran Lynch in collaboration with Prof. Jonathan Clark includes the creation and testing of different control paradigms, as well as the empirical study of the robot’s stability properties.
