Autonomous Reality Capture for Robot

The Leica BLK ARC is an autonomous laser scanning module for robots. It is designed to be integrated with robotic carriers to enable autonomous mobile laser scanning with minimal or no human intervention. Users can simply plan a scan path and set BLK ARC off on its own to scan autonomously.

Our first robotic carrier is the Boston Dynamics Spot robot. BLK ARC combined with Spot creates a fast, simple, safe, and autonomous reality capture workflow. Together, they deliver fully autonomous and repeatable scan missions to capture 3D point clouds and panoramic imagery while Spot carries BLK ARC through an environment.

Remote user operation

Plan and execute missions from a remote location, whether in the office or in the field, which also keeps you safe from hazardous areas.

Offline path planning

Create new missions and adjust existing missions for any environment using Leica Cyclone 3DR.

GrandSLAM technology

GrandSLAM combines LiDAR SLAM, Visual SLAM, and an IMU to enable fully autonomous scanning and robotic navigation.


Static and mobile scanning modes

BLK ARC can scan in static and mobile mode during the same scan mission and all scans of both types will be registered together during the mission.

LiDAR module protection

Included U-bar protects the BLK ARC module when mounted to its robotic carrier.

Simple user interface

Control and manage your BLK ARC from an easy-to-use, browser-based application: BLK ARC UI.

Upload to HxDR

Upload BLK ARC data directly from the module to HxDR, our cloud-based data storage, visualization, and collaboration platform.


  • Performs scan missions autonomously with minimal user intervention
  • Easily mounts to Boston Dynamics Spot and integrates with its sensors
  • Improves robotic navigation while capturing 3D point clouds to create 3D digital twins
  • Captures both static and mobile scans during the same scan mission
  • Can repeat scan missions autonomously for up-to-date project progress and site changes

BLK ARC UI enables the user to:

  • Operate different sensors and robotic carriers
  • Create user profiles
  • Manage robot and scan settings
  • Control robot trajectory and the detail camera
