​It’s Friday! Time for some messy prototyping/testing pictures.

A project log for FlexSEA: Wearable robotics toolkit

OSHW+OSS to enable the next generation of powered prosthetic limbs and exoskeletons. Let’s make humans faster/better/stronger!

What you see in my thesis and in my project logs is the final result. To keep it real, I decided to share with you some “action shots” taken during testing and prototyping of the different FlexSEA boards.

This one doesn’t look too bad… until you realized that I’m holding the motor shaft fixed with vise-grips, a pen and electrical tape. A few weeks after that I designed the test bench that you can see in Current Controller: Software.

To test the circuits I usually hot-glue them to scrap pieces of MDF. No time for screws! Ugly, but functional.

Here you can see a FlexSEA-Execute board covered with test probes, a RC-Hobby Wattmeter and a big flywheel used to characterize the BLDC motor at high currents. The tall bolts act as a cage in case the flywheel… well, starts flying.

And finally, sometimes there is no time for wire management or mechanical integration!

Have a great weekend!
