Bionic Arm Exoskeleton using Pneumatic Muscles

James Hobson, better known as The Hacksmith on YouTube, has created a Bionic Arm Exoskeleton that features a Teensy 3.5 at the heart of its 86-component controller board. It is a fully functioning pneumatic steel arm based on the “nanosuit” from the first-person shooter Crysis.

In Crysis, the nano-muscle suits are worn by soldiers to increase their physical strength, speed, agility, and ability to defend themselves. In a video posted to his channel, Hobson and team walk us through the process of designing one part of the suit, a bionic arm, as a demonstration of the process needed for creating a full-body suit.

In a post on, Hobson further describes the research that went into the project including examining existing Pneumatic Artificial Muscle (PAM) systems that have existed since the 50s and comparisons to human musculature systems. Hobson also shares the schematic for the circuit for those who are curious to try their hand at the project.

Hobsons other projects include light sabers, the thermal vision helmet from Predator, and Wolverine claws. If you’ve been wanting to take your cosplay to the next level, his channel is worth checking out!
