Description
- 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)
