We're building a robotics stack that lets you deploy physical AI in the real world

Our software, hardware, and machine learning stack is seemlessly integrated, allowing you to focus on building applications instead of installing packages

One complete package to program physical AI

Capable of basic manipulation and locomotion, our flagship humanoid, K-Bot ships with every tool for you to experiment with AI robotics in your life

Owning every layer, from metal to model, lets us move faster, integrate more deeply, and open-source each breakthrough for the whole world to build on

Application layer

Create, deploy, and share robot apps, tools, and policies—built by you and the community

Robot Apps Store

A single hub to install apps, customize behaviours, train new skills, and teleoperate your robot.

Coming soon

K-Lang

Control your robot with a neural interpretation domain-specific language (DSL).

ML layer

Open-source library for GPU-accelerated robot learning and zero-shot sim-to-real transfer

K-Sim

High-performance reinforcement learning framework optimized for training humanoid robot locomotion, manipulation, and real-world deployment.

High versatility for tasks such as walking, dancing, household organization, and even cooking.

Coming soonK-OS

K-VLA

A generalist policy using large-scale robot data with novel network architecture to enable the most capable and dexterous robot.

Locally run and capable of integrating with other VLAs such as Pi0.5 and Gr00t.

OS layer

Rust-based OS to run policies on the real robot, or evaluate in simulation

K-OS

K-OS

Rust-based, fast, and reliable robot operating system combining hardware, software, and firmware.

Ships with an easy-to-use Python SDK to easily develop robot applications.

K-OS Sim

A digital twin / model evaluator for the K-Scale Operating System (K-OS) using the same gRPC interface as our real robot.

Effortlessly test and refine your models in simulation.

Hardware layer

Deploy policies, VLA models and applications on robot hardware in real-time
