K-Scale Labs · Humanoid · 2025
K-Bot, from K-Scale Labs (Palo Alto), is billed as America's first open-source full-size humanoid robot — a developer- and community-driven platform in deliberate contrast to closed commercial humanoids. At launch its software provides the fundamentals: standing, walking, balancing and obeying simple commands, controllable via a mobile app or voice. Because it's internet-connected and fully open-source, K-Bot is designed to gain new skills continuously through software updates from K-Scale and the open community, with the company committing to free upgrades for early buyers until the robot reaches full autonomy — defined as handling most tasks independently with under one human intervention per day. K-Scale's roadmap integrates vision-language-action AI so K-Bot can follow complex natural-language instructions, targeting broad autonomy by around 2028. It's aimed at developers, makers, educators and autonomy researchers who want an open platform to build on. NOTE: K-Scale publishes an open-source spec/hardware repo; exact height/weight/DOF/actuator figures vary by build and are flagged for outreach rather than guessed here — open-source status, control methods and roadmap confirmed from K-Scale.
