Please be advised all Hokuyo components not in stock now have a 10-12 month lead time

Small, accurate, high-speed scanning laser range finder
Obstacle detection and localization of autonomous robots
Light source: Laser semiconductor (905nm)
Scan speed: 25ms (Motor speed 2400rpm)
Detection distance: 60m (maximum)

The Hokuyo UST-20LX Scanning Laser Rangefinder is a small, accurate, high-speed device for obstacle detection and localization of autonomous robots and automated material handling systems. This model uses Ethernet interface for communication and can obtain measurement data in a wide field of view up to a distance of 20 meters with millimeter resolution. Due to its low power consumption, this scanner is able to be used on battery-operated platforms.

This sensor uses a laser source to scan 270° field of view. Positions of objects in the range are calculated with step angle and distance. Sensor outputs these data through communication channel.

Applications

Navigation and obstacle detection (Guide path planning for mobile robots and autonomous systems)
Object positioning (control docking processes of AGVs, AGCs)
Object Profiling (cargo containers, pallets for loading & unloading)
Object measurement and detection (volume of packages, pallets, flow measurement of bulk materials)
Area monitoring (building security and entrance ways)

Size: 50mm x 50mm x 70mm (sensor only)
Weight: 130g (excluding cable)
