SOKUIKI sensor for intelligent robots

Upgraded with finer resolution.
Multi-echo functionality and IP67 protection
for harsh environments such as rain, snow and fog.
More flexible field setting is also available.



-> Synchronization functionality for preventing interference
-> More flexible field setting available
-> Built-in heater for cold environments
-> Better accuracy, finer resolution, longer scanning distance

Laser scanning image




Collision prevention

Area monitoring for collision prevention of RTGs, RMGs and AGVs


Container positioning

Possible to pick up containers precisely based on distance and angle measurements obtained from the sensor.


Terrain measurement

Terrain measurement and analysis using distance data obtained for maintenance of roads, bridges and cultural properties.


Vehicle detection

Vehicle detection on roads or within a factory as a safety measure. Also, possible to detect traffic congestion or speed of vehicles.
