Treebot: Autonomous tree climbing by tactile sensing

The design of Treebot is unique: It uses a set of flexible linear actuators connecting two gripping claws to enable it to move around like an inchworm. While the back gripper holds on, the front gripper releases and the body extends forward, enabling the robot to literally feel around for a good place to grip.
