ABW Laser Distance Sensor Array for LEGO® SPIKE™ Prime

ABW Laser Distance Sensor Array for LEGO® SPIKE™ Prime

Three laser time-of-flight distance sensors facing left, forward and right, giving your robot millimetre distance readings to walls and obstacles. Ideal for RoboCup Junior Rescue Maze wall-following and for positioning on a Soccer field. Designed, assembled and tested in Brisbane by former RoboCup competitors.

⚠️ Not permitted in RoboCup Junior Australia Standard or Lightweight Soccer: this sensor emits infrared light. It’s designed for Rescue. Always check the current year’s rules for your league.

How it works: plug the array into any port on your SPIKE Prime hub. It shows up as a colour sensor, and the three distances come through on the red, green and blue channels:

Key features:

• 3 laser time-of-flight sensors, mounted at 90° (left, front, right)

• Class 1, eye-safe, invisible (940 nm) laser
• Fits the LEGO stud/pin grid
