The problems you hit at competitions — solved
Every product starts from a real pain point on the competition floor.
Line following wobbles at speed and gets lost on busy maps
The official color sensor sees a single spot; when the line drifts, your code has to guess.
→ Pathfinder 8/16-Way: sees 8/16 points at once and tells you exactly where the line is
SPIKE has only 6 ports — not enough for motors and sensors
Adding one more sensor means removing another mechanism.
→ EXP6: one port becomes six, with its own power supply
Ultrasonic sensors are slow and report ghost readings
Sound reflects and interferes — the worst case for sumo and obstacle avoidance.
→ Ranger TOF2 / TOF8: laser ranging, with TOF8 covering 180° in front
Remote robots run away when the signal drops
Lose the gamepad link and the robot may keep executing the last command.
→ Controller PS4/PS5: bonds to your gamepad only and stops within 0.3 s of signal loss

Our Four Commitments
Plug and play
No adapter boards — plug into SPIKE / EV3 just like an official sensor.
Official blocks
Beginners keep using blocks; advanced teams unlock everything with Pybricks Python.
Smart inside
Filtering, calibration and position math run inside the sensor, so students can focus on strategy.
Named in competition rules
AERC's official rules name the Pathfinder as an allowed sensor, and WRO and other open-rule competitions accept MBC sensors.
See It in Action
Pathfinder on a competition map, plus hands-on lessons from partner coaches.

FAQ
Why do WRO teams choose Line8 or Line16 over the official color sensor?
The official color sensor samples a single point with a narrow view and is easily thrown off by reflections and shadows, so robots wobble or leave the line in fast turns. The Pathfinder series uses 8 or 16-channel arrays with built-in filtering and calibration, outputs the line position directly, and needs only 1 hub port.
Do they work with the official SPIKE Prime blocks?
Yes. Beginners can read values with the official blocks; advanced users can read the full data at high speed with Pybricks (MicroPython).
SPIKE Prime is out of ports — what can I do?
Use the MBC EXP6 6-Port Motor Expander (for LEGO® SPIKE™). It has its own isolated power and connects 6 motors or sensors through a single port.
Should I buy the SPIKE or the EV3 edition?
Choose by your controller. Editions have different connectors and protocols and are not interchangeable. See the Buying Guide, or email us your controller and we will confirm.
How do I order? Are there school discounts?
Email contactmbcrobot@gmail.com for a quote (LINE @692vcvuk also works). School and club bulk orders are welcome, and distributors can see the partner program.
