Case 01AMR

Three-dimensional distance measurement of obstacles in the direction of travel

Suitable model3D TOF sensor module: B5L-A2S-U01-010

Obstacle detection

Conventional 2D LIDAR, optical, and ultrasonic sensors are used for AMR obstacle detection applications.
All of them, however, have a limited measurement area, with a risk of collision or fall due to insufficient obstacle and/or step detection.

For 2D LIDAR: Two-dimensional measurements cannot detect obstacles fixed above or floor steps below.
For ultrasonic sensor: Small detection area.
For optical displacement sensor: Small detection area.; It cannot detect high-reflectance objects at short distances due to signal saturation and low-reflectance objects at long distances due to weak signals.; Even indoors, the accuracy of distance data deteriorates by sunlight enters through a window.

Obstacle detection by 3D distance measurement contributes to collision prevention

This sensor can measure three-dimensional distances using the time-of-flight method.
Three-dimensional distance data enables stable detection of obstacles in a wide range of up/down and left/right directions, contributing to AMR collision prevention.

Specialized processing (HDR function*) enables distance measurement of detection objects with low to high reflectance from near to far distances.

* What is HDR function?

Even indoors, sensors may be affected by sunlight shining through a window. This sensor has enhanced sunlight resistance* and can be used safely up to 100,000 lux.

* What is disturbance resistance?
