Overview

Billed as the world's first printable open-source humanoid, PLEN2 was crowdfunded on Kickstarter in 2015 with STL files, Arduino firmware and control apps all on GitHub. The small servo body walks, kicks and skates on scripted motions. The company later moved on to other products; the files remain online.
