About K-Scale Labs K-Bot

K-Bot stands 140 cm tall, weighs 34 kg, and represents K-Scale Labs' vision for democratizing humanoid robotics through open-source hardware and software. Launched mid-2025, K-Bot features complete CAD files, bill of materials, assembly instructions, and control software (ROS2-based) released publicly. Pricing targets $8,999-10,999 depending on configuration—among the most affordable full humanoids available. The first 100 units shipped late 2025 to early adopters and researchers. K-Scale emphasizes community contributions, modular design, and extensive simulation support. Applications include research, education, and independent development. Open ecosystem strategy aims to accelerate innovation through collaboration rather than proprietary control.

PROS

+ Industry-leading affordability for a full-size humanoid ($8
+ 999). Fully open-source hardware
+ software
+ and AI stack for maximum customizability. Modular design allows for easy sensor and end-effector upgrades. Robust developer tools and simulation environments (ROS2
+ KOS-Sim) provided.

CONS

- Commercial sales have been canceled and the company laid off most staff due to funding issues. Initial software capabilities are basic
- requiring significant developer effort. The physical robot is no longer in production.

Use Cases

Open-source robotics research and development Reinforcement learning and simulation testing Locomotion and balance algorithm development Deployment of custom Vision-Language-Action (VLA) models.
