The EngineAI T800, the heavyweight robot behind URKL: what EngineAI publishes about its size, power and battery
EngineAI lists the T800 at 173 cm, 75 to 85 kg, up to 450 N.m of joint torque and 3 to 5 hours of battery, in four versions. Nothing published describes a fight-specific version.
The EngineAI T800 is the heavy end of humanoid robot fighting. It is the machine URKL fights on, and, according to Roboxing's earlier reading, it also appears at ARC as its heavyweight and at CyberHero's Riyadh launch. This is what EngineAI itself publishes about it, and where that stops.
What the manufacturer lists. EngineAI's T800 page (engineai.com.cn/product-t800.html, read 12 November 2026, in Chinese) gives a height of 173 centimetres and a weight that varies by configuration, in a range of 75 to 85 kilograms. Joint torque is listed at up to 450 newton-metres. The page lists 29 degrees of freedom for the body, not counting the dexterous hands, and a leg length of 91 centimetres and an arm length of 60 centimetres. The cover panels are described as aviation-grade magnesium-aluminium alloy, the leg joints have active cooling, and the robot carries 360-degree lidar. The page gives a speed of at least two metres per second and says the hardware supports it.
Four versions. The specification table lists four versions. The Base and Development versions are listed with 25 degrees of freedom in total. The Pro version is listed at 29 plus 14 in the hands, 43 in all, and the Max version at 32 plus 14, 46 in all. The Base version uses an Nvidia Orin NX 16G computing module, the other three an AGX Orin 64G. All four list Wi-Fi 5 and Bluetooth 5.0, and the Max version adds 5G. A touchscreen handheld remote controller is listed as included with each version.
Battery. The page highlights a battery life of up to four hours, and its table gives three to five hours combined. Both figures are EngineAI's own, for the product it sells, and neither says what a robot lasts in a fight. A fight is a very different load from the work the page names: logistics, hotels, retail and factories.
What it can do, per EngineAI. The page's action showcase names walking, combination punches, a flying kick, a spinning kick and a five-kick sequence. The page footnotes say some functions are still in testing or development and that the high-power drive system requires a safe distance. EngineAI also lists armour parts for the T800 as a separate product on its site.
Where it fights. URKL, which EngineAI organises, uses it. Roboxing has recorded the T800 as ARC's heavyweight and in the CyberHero Riyadh launch. Compare the Unitree G1, the lighter robot used by UFB and ARC's lightweight class: the T800 is roughly twice its weight by the manufacturers' own figures.
What is not known. We have not found a fight-specific specification, a count of T800s in leagues, or repair or replacement rates. The page text we read shows a purchase button but no price; launch prices reported earlier by Notebookcheck have not been confirmed on EngineAI's site. Treat the table above as the product that is sold, not a measured fighter.
We will update this if EngineAI or a league publishes details of a fight-specific T800.
