UST-10LX is the new series of laser scanners from Hokuyo.  Here are some of the main features:

  • UST-10LX is light weight 130g.
  • field of view (FOV) is 270°
  • Scanning time is 25msec
  • Angular resolution is 0.25°

Field of view:



  • Robot obstacle detection (serves as their eyes)
  • Due to light weigth can be installed on UAVs for obstacle detection
  • Can be used for people counting
  • Can be used as space touch panel
  • Can be used for new floor games for kids
  • Can be used for controling other equipment such as airconditioning or lighting depending on the number of people in an area.

How to interface with new Hokuyo UST series Laser scanners



How to interface with the UST series Hokuyo Laser Scanners (e-mail us at if more questions)


1.     Power the unit by connection the BROWN wire to +12V and the DARK BLUE wire to ground of a DC 12V (300mA or more is recommended) power supply.


2.     Leave other wires unconnected.


3.     The default IP address is Port number: 10940.


4.     URG Benri data viewing tool can be downloaded from the following link.



5.     Please refer to the SCIP 2.2 communication protocol of the UTM-30LX-EW.


2.     The Hokuyo UST-10LX and UST-20LX supports most of SCIP 2.2 commands for the UTM-30LX-EW


6.     If you have a program for the UTM-30LX-EW and the program uses only single-echo commands, the program can be used with the UST-10LX and UST-20LX with minimum or no changes.
