Overview
Red Rabbit Robotics makes open-source humanoid robots. Its RX1 Humanoid is a full-size dual-arm robot that can be built for under $1,000, with kits and components sold to DIY enthusiasts, researchers, and schools. The RX1 is assembled from provided hardware and software, with open-source firmware and assembly instructions available, plus subscriptions for ongoing updates. Unlike many competitors, it shares hardware and software openly and focuses on a very affordable price to invite community collaboration, partnerships, and broad access to robotics, aiming to accelerate innovation through shared development.
