Treebot tackles trunks, branches inchworm-style

We've seen robots that can slither up a tree and shimmy up telephone poles, and now engineers in Hong Kong have developed one that can crawl up trees autonomously.

Treebot is the work of Tin Lun Lam, Yangsheng Xu, and colleagues at the Advanced Robotics Lab in The Chinese University of Hong Kong.

It was designed to demonstrate how an autonomous robot can implement path and motion-planning algorithms.

A paper about Treebot was presented recently at the International Conference on Intelligent Robots and Systems (ICRA) in Shanghai.

It uses grippers and tactile sensors attached to its Slinky-style body to slowly move its front, then its back, up a trunk like an inchworm.

Although it lacks sophisticated sensors, Treebot can pick the best path to follow up a tree, and handle angled trunks, branches, and payloads of 3.8 pounds. … Read more
