by Hokuyo


The URG-04LX is a compact, light-weight scanning laser rangefinder with serial (RS0232) and USB interfaces, and a range of 20 mm to 5.6m and a  240° field of view.  The Hokuyo lasers are compact and light, making them ideal for mounting on end effectors, aerial vehicles, or small mobile platforms.


  • Outdoor/indoor 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
