Leica BLK ARC is an autonomous laser scanning module for robots. It can be integrated with robotic carriers to enable autonomous mobile laser scanning. BLK ARC combined with robotic carriers creates a fast, simple, safe, and autonomous laser scanning work



Brand New Leica BLK ARC Be fully autonomous with our laser scanning module for robots. Reality capture takes another step forward with the Leica BLK ARC, an autonomous laser scanning module that integrates with robots. The BLK ARC, combined with a robotic carrier, performs fully autonomous scanning and navigation with GrandSLAM technology, offers remote and offline scan mission planning, and provides complete control through a browser-based interface. Integration with a variety of robotic carriers makes the BLK ARC an essential component to autonomous reality capture, and it is ready to scan wherever you tell it to go.

The first robotic carrier for the BLK ARC 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.

With BLK ARC UI, an easy-to-use browser-based user interface, users can plan scan paths remotely using existing drawings or BIM models of your building, including large and complex spaces. This enables the user to save time and allow BLK ARC to scan complex or hazardous environments while remaining in a safe location.

BLK ARC UI bridges the distance between the office and the field and enables uploads of offline missions planned in Cyclone 3DR to the robot. Once the mission is complete, BLK ARC UI helps to direct the data either into our legacy software, Leica Cyclone, or to direct upload from the field to HxDR.

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
  • 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.
