EngineAI T800 EDU Open Source Edition Humanoid Robot

Most full-size humanoids ask you to choose between raw athletic performance and the freedom to program it. The EngineAI T800 Open Source Edition gives you both. It uses the same powerful body that made the T800 famous for flying kicks and punch-kick combinations, paired with the sensors, computing power and software access a development team needs to build its own behaviors.

The Basic Edition runs EngineAI's motions. The Open Source Edition lets you write your own.

EngineAI, a humanoid robotics company based in Shenzhen, launched the T800 in late 2025 as its first heavy-duty, full-size general-purpose humanoid. The company offers it in four editions (Basic, Open Source, Pro and Max) that share the same 173 cm frame and 450 N·m joint torque and differ in sensors, computing, hands and development access. The Open Source Edition sits at the point where the platform opens up to developers.

Background

What makes the Open Source Edition different

Compared with the Basic Edition, the Open Source Edition adds three things that matter to developers:

1. 3D LiDAR for mapping, localization and obstacle avoidance, which the Basic Edition does not include.
2. An AGX Orin 64 GB high-computing module in place of the Basic Edition's Orin NX 16 GB, with an upgrade to Thor available on request.
3. Secondary development support through EngineAI's SDK and API, so your team can deploy its own control policies, perception pipelines and applications.

The mechanical platform is otherwise the same: identical height, joint layout, actuators and structure.

Physical design

The T800 is built from aviation aluminum and titanium, with a streamlined, impact-resistant shell. Its joints use EngineAI's ultra-high-speed internal rotor permanent magnet synchronous motors and industrial-grade crossed roller bearings, delivering up to 450 N·m of torque at the most powerful joints. That torque is what enables the explosive, high-dynamic motion the T800 is known for.

To sustain that performance, the legs use active air cooling, which EngineAI says keeps the joints at peak output under heavy loads and high temperatures.

Joint layout

The Open Source Edition has 25 degrees of freedom:

• 6 per leg
• 5 per arm
• 1 at the waist
• 2 at the neck

It does not include dexterous hands. The configuration is built for locomotion, balance and whole-body control rather than fine manipulation.

Perception and computing

The Open Source Edition pairs an ultra-wide field-of-view binocular camera with 3D LiDAR for omnidirectional awareness and real-time obstacle avoidance. An 8-core CPU handles base control, while the AGX Orin 64 GB module provides the headroom for running learned policies, perception models and onboard AI. Wi-Fi 5 and Bluetooth 5.0 handle connectivity, and a built-in microphone and speaker support voice interaction.

Battery and operation

Power comes from a lithium battery pack with intelligent quick-release, so packs can be swapped rather than waiting for a recharge. EngineAI quotes 3 to 5 hours of operation per charge depending on the workload. A handheld touchscreen remote controller is included.

Technical Specifications

Performance figures may vary with the task, posture and operating conditions.

Choosing Your T800 Edition

Choose the Open Source Edition if your work centers on locomotion, balance, reinforcement learning or whole-body control and you want full software access at the lowest entry point. Step up to the Pro if you need manipulation: it adds 7-DoF arms, a 3-DoF neck and two 7-DoF dexterous hands with tactile sensing rated for 5 kg each. The Max adds a 3-DoF waist and 5G connectivity.

Applications

• Locomotion and reinforcement learning research. Train and deploy walking, running, recovery and dynamic motion policies on a full-size, high-torque body.
• Whole-body control. Develop controllers that coordinate legs, waist and arms through high-dynamic movement.
• Perception and navigation. Build mapping, localization and obstacle avoidance on the onboard LiDAR and stereo vision.
• Embodied AI. Run perception models and learned policies onboard with the AGX Orin 64 GB module.
• Robot competitions and sport. Develop routines for combat, martial arts and athletic events.
• Application prototyping. Explore logistics, hospitality, retail and human-robot collaboration concepts, the scenarios EngineAI targets for the T800.
• University teaching. Give students hands-on access to a real full-size humanoid and its software stack.

What to Plan For

• Respect the power. EngineAI itself advises that the T800's actuators are extremely powerful and that operators must keep a safe distance. Define a test area, keep bystanders clear and use a safety gantry when testing new policies.
• No hands on this edition. If your project needs grasping or manipulation, choose the Pro or Max.
• Software takes expertise. Secondary development assumes a team comfortable with robotics software, simulation and control. Review the SDK and API documentation before committing.
• Plan battery logistics. At 3 to 5 hours per charge, spare battery packs keep development days productive.
• Expect evolution. EngineAI notes that some showcased features are still being refined and released over time, and that humanoid robotics remains an early-stage field.
• Civilian use only. The T800 is designated for civilian use, and hazardous modifications are prohibited.

Frequently Asked Questions

What is the EngineAI T800 Open Source Edition?

It is the developer configuration of EngineAI's full-size T800 humanoid. It offers 450 N·m joint torque, 3D LiDAR, an AGX Orin 64 GB computing module and full secondary development access through EngineAI's SDK and API.

What is the difference between the T800 Basic and Open Source Editions?

They share the same body. The Open Source Edition adds 3D LiDAR, upgrades computing from Orin NX 16 GB to AGX Orin 64 GB, and enables secondary development.

Does the T800 Open Source Edition have hands?

No. It has 5-DoF arms without dexterous hands. The Pro and Max Editions add two 7-DoF dexterous hands with tactile sensing.

How tall and heavy is the EngineAI T800?

It stands 173 cm tall and weighs 75 to 85 kg depending on configuration.

How long does the T800 battery last?

EngineAI quotes 3 to 5 hours per charge depending on the workload, and the quick-release battery can be swapped for continuous operation.

Can I upgrade the T800's computing power?

Yes. The Open Source Edition's AGX Orin 64 GB module can be upgraded to Thor on request.
