MCM Robotics · TX series robot brains

A brain that lets your robot find its own way

The TX series is a two-part controller for legged, wheeled and humanoid robots. A high-compute brain sees, maps and plans. A rugged cerebellum keeps every motor in step. Add our navigation stack and control platform, and the robot patrols, delivers or guides on its own. MCM Robotics supplies, fits and supports it in South Africa.

How the TX series is built

Brain and cerebellum, on separate boards

In people, the brain decides and the cerebellum co-ordinates movement. The TX series splits the work the same way, so heavy AI work never has to compete with balance and motor control.

TX-1/2

The brain thinks

Cameras, LiDAR, AI models, mapping, route planning, speech and the 5G link to the control platform.

TX-3

The cerebellum moves

Reads an industrial attitude sensor and drives the motors over isolated CAN FD and RS485, so motor faults and back-EMF stay away from the electronics.

ANY

One brain, many bodies

The same set fits quadrupeds, wheeled-legged robots, humanoids and unmanned ground vehicles. Motors with different interfaces can share a robot.

TX architecture: sensors feed the brain, the brain sends goals to the cerebellum, the cerebellum drives the motors, and the brain links to the control platform over 5G.

Fits the robots we sell

Made for Unitree Go2, A2 and B2

We fit the TX set to the Unitree quadrupeds we already supply, so you get the robot and its autonomy from one South African team.

Unitree Go2

Unitree Go2

Compact quadruped for patrols, guided tours, research and education.

Unitree A2

Unitree A2

Industrial quadruped for inspection and security rounds.

The TX range

Three boards. Pick the brain, add the cerebellum.

Two brains at different compute levels, and one cerebellum that pairs with either. All three take a wide DC input straight from the robot's battery and work from −25 to 70 °C.

TX-2 robot brain board

TX-2

Brain · D-Robotics S100

A brain with 80 or 128 TOPS, built as an integrated brain-and-cerebellum controller, so smaller robots can run on one board. Wi-Fi and Bluetooth are built in alongside 5G, and two USB 3.0 ports take extra depth cameras or storage.

TX-3 robot cerebellum board

Cerebellum · Rockchip

The cerebellum looks after balance and movement. An industrial attitude sensor feeds the control loop, and isolated motor buses let you mix motor brands without risking the board. It runs from as little as 9 V.

Control platform

One screen for the whole fleet

Every TX robot reports to a cloud control platform over 5G. Your control room sees what the robots see, and gets told when something needs a person.

  • Unmanned patrols, 24/7. Missions run on a schedule around the clock, with live HD video and sensor data streamed back.
  • AI hazard spotting. Trained detectors flag problems such as blocked fire exits, illegal parking and unsafe charging cables, and attach the evidence.
  • Alerts that close the loop. Every alert is tracked from detection to response to done.
  • Remote takeover. An operator can drive any robot from the platform, then hand it back to autonomy.
  • Map management. View and update point-cloud maps remotely, with no site visit.
  • Remote power and audio. Switch robots off or wake them over 5G, and speak through the robot's loudspeaker.

Where it works

Built for real jobs

The same brain and navigation stack runs very different robots. These are the jobs TX-equipped robots already do in service.

Wheeled-legged security patrol robot with beacon and cameras
Estates · industrial parks · factories · power plants · campuses

Security patrols

Round-the-clock patrols that replace repetitive and high-risk rounds. The robot watches for blocked fire exits, illegal occupation and crowds, speaks through its loudspeaker, and raises alerts in the control room.

Wheeled-legged delivery robot carrying a closed cargo box on a wet street
Malls · office parks · residential estates · warehouses

Last-metre delivery

A wheeled-legged robot with a sealed, lockable compartment delivers door to door. Lifts and access control are integrated, electronic fences and collision warnings keep it safe, and it returns to a charging pod on its own.

Quadruped guide robot walking beside a visitor in a park
Museums · visitor centres · tourism sites · service halls

Guided tours

Guide robots navigate a planned route and give commentary in several languages. They answer questions through a knowledge base, and can follow a visitor on request.

Vehicle plants · yards · logistics hubs

Yard and vehicle moves

Autonomous driving for fixed routes: path tracking, stopping for obstacles and pedestrians, automatic parking and garage entry. QR markers keep positioning exact along long runs.

Universities · TVET colleges · research labs

Education and research

An open development platform for robotics courses and R&D, with a simulation pipeline built on NVIDIA Isaac Sim. Train behaviours in simulation before real-world testing, to save time and cost.
