K-Scale Labs Unveils K-Bot: An Open-Source $899 Housebot Built for Developers

K-Scale Labs is reshaping the robotics landscape with the introduction of K-Bot, a fully open-source humanoid robot engineered specifically for developers, researchers, and advanced hobbyists. With a focus on accessibility and innovation, K-Scale Labs is lowering the barrier to entry for robotics development while maintaining industrial-grade performance.

Standing 4′7″ tall and weighing just 77 pounds, K-Bot is compact yet powerful. It features high-torque 120 N·m actuators, modular end-effectors, and a reinforced lightweight frame optimized for agility and durability. Unlike proprietary systems, every aspect of K-Bot—from its mechanical schematics to its firmware—is open source, enabling users to fully customize, repair, and enhance the platform to fit their project needs.

K-Bot runs on K-Scale's custom Rust-based operating system, K‑OS, which seamlessly integrates with their robust machine learning stack. Developers can take advantage of K‑Sim, a reinforcement learning environment tailored for robotics training, and K‑VLA, a suite of vision-language-action models that allow K-Bot to perceive, interpret, and interact with its environment using advanced AI.

Designed as a modular ecosystem, K-Bot supports plug-and-play hardware expansions, real-time sensor integration, and cloud-assisted compute workflows. This makes it ideal for cutting-edge research in human-robot interaction, mobile manipulation, and autonomous learning.

Priced at $8,999, K-Bot is aggressively positioned to compete with much more expensive commercial humanoids, while remaining infinitely more hackable. K-Scale Labs is currently accepting $100 pre-orders, with deliveries scheduled to begin in July 2025.

With K-Bot, K-Scale Labs is delivering more than just a robot—they’re opening a platform that invites the global developer community to accelerate the future of humanoid intelligence, together.
