3D-Printed Sleeve for Rock Climbing Robot

Featured here is a new microspine-based palm design for rock-climbing robots. These palms use microspines that can support four times the weight of previous designs. The design of these new spines is straightforward: each 15-mm steel spine sits in a 3D printed sleeve, with a spring that pushes it down towards the surface it’s trying to grip. That single compliant axis helps the spines grip very rough surfaces, and 60 spines will fit into a single 18-mm x 18-mm “tile.”
