UST-20LX

HOKUYO

Extremely light-weight laser scanner smart mini

20m range and 270° field of view. IP65 and ethernet interface.

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 10 meters with millimeter resolution. Due to its low power consumption, this scanner is able to be used on battery-operated platforms.

Its smaller brother UST-10LX has similar characteristics but 10 m range.
