Stable Perception in Challenging Environments

The SR18 addresses real-world robotic deployment needs through its sensing architecture, near-ground coverage, and remote maintenance capability.

SR18 perception for a commercial cleaning robot in a reflective environment

Reduced Inter-Channel Crosstalk

An integrated transmitter-receiver architecture pairs each emitting channel with a dedicated detector, helping reduce interference from strong reflections and maintain consistent object contours and ranging data.

Dedicated channel detection
SR18 downward channels and vertical field-of-view coverage

Short Minimum Range, All-Around Coverage

Downward-angled channels extend coverage toward the ground, supporting the detection of low-lying obstacles and terrain changes.

−8° to +40°

Remote Firmware Updates

Supported features and performance improvements can be delivered remotely after deployment, reducing on-site servicing and hardware replacement needs.
