Printing Your Own Exoskeleton | Hackaday



Whereas not fairly in a cave, the concept of creating your individual exoskeleton with restricted instruments does have a Tony Stark esque vibe. [Andrew Piccinno] is a mechanical engineer pursuing the dream of 3D printing a full-body exoskeleton called 3X0. It’s a undertaking he’s been ruminating on since school, however the work actually started in earnest about 5 months in the past. Sadly, there are too many footage to incorporate right here, but check out his Instagram or makeprojects for extra images.

To verify elements match, [Andrew] began with making a mesh of his physique. After working fifty footage of himself holding comparatively nonetheless via some photogrammetry software program, he had a good mesh. Whereas measurements weren’t millimeter-accurate, the relative sizes of all the pieces have been moderately correct. Whereas the design is modeled together with his measurements in thoughts, all of the totally different items are parametric, which in idea would enable somebody to tweak the designs to suit their very own physique.

To this point, all of the elements have been completely 3D printed, apart from metal balls bearings, gasoline pistons, and pressure bands. The non-3D printed elements are picked to be simple to acquire because the gasoline piston is simply 100 N furnishings pistons. The design course of consists of fairly a little bit of math, movement examine, and simulation to verify the half that he’s printing won’t solely match however transfer accurately. Many elements, such because the shoulder, are constructed round a big customized bearing that enables the piece to maneuver accurately with the consumer’s joints.

Whereas nonetheless in the course of improvement, [Andrew] has made some critical progress, and we’re trying ahead to seeing it accomplished. The present design is primarily passive with only a few springs and pistons, however he’s already trying ahead to creating it lively to the diploma that it could increase a consumer’s motions moderately than simply taking the load off. It’s clear that [Andrew] believes that exoskeletons are a glance into a possible future, and we couldn’t agree more. In an identical vein, maybe the techniques used in this powered exoskeleton arm on a budget may very well be used to energy the 3X0?
