One time, when my car broke down, I spent an hour physically pushing it half a block just so that I could avoid getting a parking ticket. If only I’d had an exoskeleton that let me simply lift it up …
Inventor James Hobson, who calls himself The Hacksmith, is obsessed with exoskeletons. In 2014, inspired by the movie Elysium, The Hacksmith built an upper-body design that let him curl 170lbs. This year, he designed a lower-body solution that lets him lift a car.
More specifically, Hobson’s latest exoskeleton allows him to pick up the back of a Mini Cooper:
The Hacksmith says he is on a quest to build a full-body powered exoskeleton. In fact, according to his post on Hackaday, the mechanical engineer quit his full-time job as a product developer late last year to focus on “exoskeletons, YouTube, and effectively become a ‘Hacker for Hire’.”
And that’s how the project kicked off:
Shortly after that, the German Science show Galileo reached out and asked if they could feature my new exoskeleton on their show — I agreed, and may or may not have promised them a feat of strength I wasn’t even sure I’d be capable of doing — lifting a car.
Like most engineers, I work best under pressure, so with less than a week to go before the interview, we started working on the legs. Getting the strength to lift a car was quite easy. I had a pair of 63mm bore diameter pneumatic cylinders, which at 125PSI are capable of lifting over 800lbs a piece. The fun part was attaching them to my body in order to do it.

Again, many will argue that he didn’t lift the car completely off the ground — just the back two wheels. But don’t worry, according to the video, his next goal is to flip the car.
