# FAQ

Common questions about the company, product selection, development, business, and support.

## A. Company & Brand

### A1 What kind of company is LimX Dynamics?

LimX Dynamics was founded in January 2022 and is headquartered in Shenzhen, China. We are an embodied-AI robotics OEM that develops its own robot hardware design and manufacturing, cerebellum–cerebrum fusion technology, and an embodied-agent operating system. On that basis we have built a three-layer technology stack: System 0 (whole-body motion-control foundation model), System 1 (humanoid VLA/WAM skills and AI infrastructure), and System 2 (LimX COSA, our embodied-agent OS). Our product line covers the full-size humanoid robots LimX Oli and LimX Luna; the multi-form robots TRON 2 and TRON 1; the humanoid brain systems LimX COSA and COSA 0.5; and the open-source VLA engineering foundation FluxVLA Engine. See [/en/about](/en/about) for more.

### A2 What is embodied intelligence, and what does LimX Dynamics do in this field?

Embodied intelligence is AI that perceives, decides, and acts in the physical world through a body — extending intelligence beyond the screen. LimX Dynamics works across three core technologies: original design and manufacturing of robot hardware, cerebellum–cerebrum fusion (whole-body motion control plus VLA), and LimX COSA, our embodied-agent operating system. These come to life in four robots — the full-size humanoid robots **LimX Oli** and **LimX Luna**, and the multi-form robots **TRON 2** and **TRON 1** — as well as the open-source VLA engineering foundation FluxVLA Engine. For positioning and use cases, see the next section, Products & Selection.

## B. Products & Selection

### B1 What products does LimX Dynamics offer, and what is each one used for?

LimX Dynamics builds full-size general-purpose humanoid robots and the multi-form TRON series. Our lineup includes LimX Luna, an interactive humanoid for commercial performance (malls, museums, theme parks, stages), where many units can run synchronized shows; LimX Oli, a general-purpose humanoid for embodied-AI research in universities, labs, and companies, for algorithm validation and secondary development; TRON 2, a multi-form embodied robot for dual-arm manipulation and mobility, such as flexible tasks, data collection, and VLA training; and TRON 1, a multi-form biped for reinforcement-learning and locomotion research and teaching. On the software side, the core is **LimX COSA**, our embodied-agent operating system, alongside the open-source VLA engineering foundation FluxVLA Engine and its companion cloud training platform FluxTraining. For more, visit our News Center ([/en/news](/en/news)).

### B2 Which product should I choose, and how do I know which one fits my needs?

Choose by use case: Luna for commercial performance and on-site interaction; Oli for research, development, and algorithm validation; TRON 2 for dual-arm manipulation and VLA development; TRON 1 for reinforcement-learning research. For positioning and specs, see the product comparison table.

### B3 What is the difference between Luna and Oli, and which one should I choose?

Both are full-size humanoids, each with a different focus. Luna (160 cm / 54 kg / 27 DoF) is built for commercial performance and interaction — a face display, multimodal interaction, intelligent swarm control, and dance performance, ready to use out of the box. Oli (165 cm / 55 kg / 31 DoF) is built for research and development, with full-Python programming, a modular SDK, and open interfaces. Choose Luna for performance and interaction; choose Oli for development and research.

### B4 What is the difference between TRON 1 and TRON 2, and which one should I choose?

Both switch between multiple forms but serve different needs. TRON 1 is a biped: an all-in-one modular foot switches it between point-foot, biped, and wheeled-biped configurations, and it is designed as an entry point for reinforcement-learning research — ready to use out of the box. TRON 2 is an embodied robot that can be configured with dual arms, biped legs, or wheeled-biped legs. Each arm has 7 DoF, the dual-arm payload is 10 kg, and it ships with a one-stop VLA data-collection platform with real-robot data. Choose TRON 1 for RL research; choose TRON 2 for manipulation tasks and VLA development.

### B5 What forms and configurations do your robots support?

Our robots come in multiple forms and configurations. Luna and Oli are both full-size humanoid bipeds. TRON 1 uses an all-in-one modular foot to switch between point-foot, biped, and wheeled-biped forms — the software detects the current form and switches locomotion modes automatically. TRON 2 can be configured with dual-arm, biped, or wheeled-biped modules.

### B6 What can each product do? (Capability overview)

Luna: a full-size interactive humanoid with 27 DoF, a face display, and multimodal interaction, supporting intelligent swarm control and dance performance for commercial performance (details: [/en/products/luna/faq](/en/products/luna/faq)). Oli: a full-size general-purpose humanoid with 31 DoF, depth cameras, and our in-house 6-axis IMU, with full-Python programming and a modular SDK for research and development (details: [/en/products/oli](/en/products/oli)). TRON 2: a multi-form embodied robot with 7 DoF per arm, a 10 kg dual-arm payload, and a 1.5 m working height, shipping with a one-stop VLA data-collection platform (details: [/en/products/tron2](/en/products/tron2)). TRON 1: a multi-form biped, ready to use out of the box for reinforcement-learning research. For forms and configurations, see the previous question.

### B7 What are LimX COSA, VGM, and DreamActor?

LimX COSA is an embodied-agent operating system (Cognitive OS of Agents) — a physical-world-native agentic system that manages all the models, skills, memory, and emotions built into the robot, coupling high-level cognitive planning with low-latency motion-control loops so a humanoid can perceive and move at once and "think while working". VGM (Video-Generated Manipulation) is a manipulation algorithm released in February 2025 that trains manipulation policies from human video data, reducing reliance on teleoperation data. DreamActor is a new paradigm for embodied-AI training, released in September 2025, using a multi-source data recipe, with related research published at CoRL 2025. All three are algorithm- and system-level capabilities used with our robot hardware; see the glossary at [/en/glossary](/en/glossary) for details.

## C. Development & Ecosystem

### C1 Do you provide an open SDK and development interfaces? What language do I develop in?

We provide open development interfaces and tooling. Oli supports full-Python programming, a modular SDK, open high- and low-level interfaces, and a complete URDF; TRON 1 and TRON 2 provide open SDKs and a Python toolchain; and Luna supports content creation and secondary development through the official Limx Studio app.

### C2 What have you open-sourced, and where can I get it?

We open-source several resources through two channels. For FluxVLA Engine, the code is at github.com/FluxVLA/FluxVLA, docs at fluxvla.limxdynamics.com, and model weights on huggingface.co/limxdynamics/FluxVLAEngine and modelscope.cn/models/LimXDynamics/FluxVLAEngine. For our products (Oli and TRON), secondary-development and open-source resources are published at github.com/limxdynamics. TRON 2 also releases real-robot data, and developers can join the LandX community.

### C3 Which simulation platforms are supported?

For simulation, Oli supports NVIDIA Isaac Sim, MuJoCo, and Gazebo; TRON 1 and TRON 2 support mainstream simulators and are compatible with ROS2 and ROS; in FluxVLA Engine, the simulation layer connects to Isaac Sim and LIBERO. Luna's simulation and training run on the official cloud desktop.

### C4 What is VLA? What are FluxVLA Engine and FluxTraining?

VLA (Vision-Language-Action) means a model that turns visual and language input directly into robot actions. FluxVLA Engine is our open-source, standardized engineering foundation for embodied intelligence. It uses unified configuration, standard interfaces, and decoupled modules to connect the full pipeline — data processing, model training, simulation evaluation, and real-robot deployment — with 5–10× faster inference. FluxTraining is the companion cloud platform for training and managing models online. See the glossary at [/en/glossary](/en/glossary) for details.

### C5 What external sensors and interface expansion options are supported?

Interfaces vary by product. Oli provides Gigabit Ethernet, USB 3.0–3.2, and 24 V / 12 V power outputs, with an Intel RealSense D435i depth camera on the head and chest. TRON 1 offers three expansion kits: mobile manipulation, voice interaction (with an NVIDIA NX high-compute module), and perception (LiDAR plus depth camera). TRON 2 supports ROS2 and ROS for connecting external sensors and host systems. For the full interface list, see each product page and the Documentation Center ([/en/documents](/en/documents)).

## F. Safety & Reliability

### F1 What safety features do your products have?

Take Luna: it has four layers of protection — collision detection, fall detection, motion abort, and an emergency-stop button. TRON 2 adds safety-boundary protection and dual-power redundancy: if power is cut, its arms slowly retract to a safe position. In any scenario, embodied robots must be operated per their operating and safety instructions — never bypass the built-in safety protections.

### F2 How is safety ensured in human-robot collaboration?

During human-robot collaboration, follow the operating instructions and on-site safety requirements, keep a safe distance, operate only under trained personnel, and never bypass the built-in safety protections. For the safety features themselves, see the previous question.
