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)
