The short answer

The T800 in plain English

The EngineAI T800 is a human-sized robot with powerful joints, cameras, onboard computers, and enough freedom of movement to walk, turn, punch, kick, fall, and get back up.

It was not made only for URKL. EngineAI sells the T800 as a general-purpose humanoid platform. URKL takes that platform and makes it the common starting point for every team.

The machine

What is the EngineAI T800?

T800 is a full-size humanoid robot made by EngineAI, a robotics company based in Shenzhen, China.

“Humanoid” simply means its body follows the broad shape of a person: a head, torso, two arms, and two legs. That shape lets researchers train human-like movement, but it also creates a hard control problem. The robot must constantly manage its weight and balance while many joints move at once.

EngineAI publishes several T800 editions. The figures in this guide come from its current Basic Edition listing unless noted otherwise. They are product-page figures, not a promise that every URKL robot has an identical setup.

The physical facts

How big and powerful is the T800?

Height
173 cm
Listed weight
75–85 kg
Maximum joint torque
450 N·m

At 173 cm, the T800 is close to average adult human height. Its listed weight changes by edition, so 75–85 kg is a range—not one fixed competition weigh-in figure.

What does 450 N·m mean?

It is the maximum torque EngineAI lists for a joint. Torque is turning effort: how strongly a motor can rotate a joint around its axis. It is not the same thing as punch force, and EngineAI does not publish a punch-force number on the product page.

Joints and motion

How does the T800 move?

The Basic Edition lists 25 degrees of freedom—25 controlled ways its joints can rotate.

Legs

12 movements

Six per leg across the hips, knees, and feet.

Arms

10 movements

Five per arm across the shoulders and elbows.

Body

3 movements

Two at the neck and one at the waist.

EngineAI says the hardware supports movement speeds of at least 3 m/s. That is a hardware specification, not a measured URKL running speed. Real fighting movement is limited by balance, traction, software, armor, safety rules, and the move being attempted.

What is inside

What can the T800 see and compute?

EngineAI’s Basic Edition specification lists an Intel depth camera, an Orin NX 16 GB high-performance computer, and a separate Intel robot computer with an optional RK3588 module. It also lists Wi-Fi, Bluetooth, USB, and wired network connections.

The URKL connection

Why does every URKL team use the same T800?

A shared robot shifts the competition away from who can build the biggest machine and toward who can make the same machine perform best.

The published rules name the T800 as URKL’s designated robot. They say the event is meant to test movement control, balance, perception and decision-making, power systems, and structural protection.

That is the basic fairness idea. The body starts from a common platform; the team’s work determines how well it performs.

Where teams compete

What do URKL teams change?

  1. They train movements.Teams turn human motion data and their own high-difficulty moves into actions the T800 can perform.
  2. They make the robot stay upright.Balance, disturbance recovery, getting up, and smooth transitions matter when a robot is pushed or hit.
  3. They build reactions and tactics.Perception and decision software can help the robot choose when and how to move, although the live control rules remain unclear.
  4. They protect the machine.The rules encourage self-developed protective equipment and engineering optimization while rejecting destructive or dangerous modification.

The online qualifier scored movement quality in a simulated T800. Teams were judged on reproducibility, difficult moves, resistance to disturbances, recovery work, and smooth motion. Moving that software onto a real robot is the next test.

Protection

What is the T800 fighting armor?

EngineAI calls its official protective outer shell FA01, short for Fighting Armor.

The company describes FA01 as protective armor for compliant robot fighting, exhibitions, and entertainment performances. It also says the armor can be personalized. The URKL rules separately encourage teams to develop protective equipment.

An important distinction

Is the URKL T800 the same as the commercial robot?

It is the same named robot platform, but the public evidence does not support treating every product-page detail as a fixed URKL specification.

QuestionCommercial product pageURKL competition
Robot modelT800T800 is the designated model
Weight75–85 kg by editionFinal competition weigh-in rules not published
ArmorFA01 is offered separatelyAllowed final configuration not published
ControlOnboard computers and handheld remote listedExact fight-control setup not published

This distinction matters because product pages describe what a platform can include. Competition rules define what actually enters the ring. URKL’s detailed physical-stage rules are still marked for later publication.

Evidence check

What is confirmed—and what is still unknown?

Confirmed

  • EngineAI makes the T800 in Shenzhen, China.
  • The current product page lists 173 cm height and a 75–85 kg edition range.
  • The Basic Edition lists 25 degrees of freedom, an Intel depth camera, and Orin NX 16 GB computing.
  • URKL designates the T800 as its standard robot model.
  • Teams compete through movement, balance, recovery, perception, tactics, protection, and engineering work.

Not published

  • The final T800 hardware specification for each physical tournament stage.
  • The exact mix of autonomous behavior and human control during fights.
  • A complete list of permitted and prohibited hardware changes.
  • Whether every team must use EngineAI’s FA01 armor.
  • An official measurement of T800 punch or kick force.

Quick reference

EngineAI T800 questions

What is the EngineAI T800?

The T800 is a full-size humanoid robot made by EngineAI in Shenzhen, China. URKL names it as the standard robot platform for its first competition season.

How tall and heavy is the T800 robot?

EngineAI’s current product page lists a height of 173 cm and a weight of 75 to 85 kg depending on the edition.

Do all URKL teams use the EngineAI T800?

Yes. The published URKL rules name the T800 as the designated humanoid robot model. The detailed hardware configuration for later competition stages has not yet been published.

What do URKL teams change on the T800?

Teams work on movement software, balance, recovery, reactions, tactics, engineering optimization, and permitted protective equipment. The rules reject destructive modifications and have not yet published the complete hardware limits for the physical competition stages.

Is the URKL T800 autonomous or remote-controlled?

The public material reviewed here does not clearly explain the exact mix of autonomy and human control used in URKL fights. The commercial T800 includes onboard computers and a handheld remote, but that does not prove how tournament robots are controlled.

Does 450 N·m mean the T800 punches with that force?

No. EngineAI lists 450 N·m as maximum joint torque. Torque describes turning effort at a joint; it is not a published measurement of punch force.

Is the EngineAI T800 connected to the Terminator?

EngineAI presents T800 as the name of its own humanoid robot. The official material reviewed for this guide does not state a connection to the fictional character with the same model number.
