A small, lightweight, low-power, low-cost ultrasonic sensor mounted above the prosthetic ankle to detect and avoid tripping hazards. Very cool!

It is possible to measure changes in metabolic rate in the low ones of percents using typical indirect respirometry systems with good experimental design: within-day, within-calibration comparisons; N >= 10-ish; ideally with double-reversal [ABCCBA] presentation for ordering effects.

I should add: Keenon Werling is the amazing PhD student and software developer leading the addbiomechanics.org project.

Right on :D. We wanted the web app to be simple and user friendly, but for those who want to roll up their sleeves the entire addbiomechanics.org stack is publicly available:
github.com/keenon/AddBi...

If you go offline, please post your data afterwards.

Coming soon: automatic marker labelling and gap filling...

We hope to create a tool that makes collecting high-quality biomechanics datasets far easier,

AND generate a large public dataset in a consistent format to allow application of modern AI/ML techniques.

Thanks, Brian!
