Devanthro · Humanoid · 2013
Roboy, from Devanthro (originating at TU Munich / Fortiss in 2013), is an open-source tendon-driven musculoskeletal humanoid built to mimic the human muscle-tendon system rather than use conventional rigid joints. Its 'myorobotic' actuation pairs electric motors with springs and tendons to emulate biological muscles, giving compliant, human-like movement, and the project has iterated through multiple generations exploring biologically-inspired robotics, telepresence avatars and prosthetics research. Devanthro develops Roboy as an open platform (ROS-based) with an active research and maker community, positioning it alongside other musculoskeletal efforts like Clone's Myofiber androids and the University of Tokyo's Kengoro. NOTE: Roboy exists in several research generations with varying configurations; Devanthro publishes limited fixed spec tables (exact DOF/height/weight vary by build) — those are flagged for outreach rather than guessed; the tendon-driven myorobotic architecture, open-source status and research focus are confirmed.
