In WRO RoboMission, precision isn’t optional — it’s everything. Anyone can get a robot to work once, but only a well-designed system can deliver the same result ten times in a row.

MA321 Matrix R4 MissionGo Set was built around that truth from the ground up.

Every part of the kit — control, sensing, structure, and programming — is designed to help teams achieve repeatable, competition-grade accuracy on every mission attempt. Making your robot run straighter, smoother, and more reliable than ever.

A New Standard of Line-Following Performance

The highlight of this generation is the brand-new 10-channel Line Tracer, giving MATRIX robots the fine-tuned responsiveness that mission-based competitions demand. It doesn’t simply “follow a black line.” It reads deviations at high resolution, corrects direction smoothly, and handles curves with confidence. 

With MA321 Matrix R4 MissionGo Set, mission runs no longer depend on luck — they depend on skill. 

Mechanical Breakthrough: LEGO-Compatible Connector 

MA321 Matrix R4 MissionGo Set introduces a major structural upgrade: the LEGO-compatible connector. 

Snap it in, and LEGO elements connect securely to the MATRIX metal system. 

Teams can now combine: 

• LEGO’s creative flexibility 

• MATRIX’s strength, precision, and durability 

This unlocks structural possibilities that were never practical before. 

Your existing LEGO library instantly becomes an asset — not a separate ecosystem. 

Designed to Remove Barriers — and Raise Performance 

MA321 Matrix R4 MissionGo Set eliminates the steep learning curve that slows down new teams. 

In a single integrated package, teams receive: 

• A stable, competition-ready control system 

• High-precision line tracking 

• Flexible metal + LEGO-compatible building options 

• Intuitive programming platform 

• Beginner-friendly starter robot design
