MA321 Matrix R4 MissionGo Set was built around that truth from the ground up.
MA321 MATIX R4 MissionGo Set
For teams that demand precision, consistency, and competition-grade performance.

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.
*Product shown in the video is Demo Version. Please refer to the assembly guide for official model version.*

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.
