Seamless autonomous laser scanning module for robots


The Leica BLK ARC is designed to be integrated with robotic carriers, such as the Boston Dynamics, Spot Robot, 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. 

The 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. 

Using the BLK ARC, you can: 

  • Easily mount to Boston Dynamics Spot and integrate with its sensors 
  • Perform scan missions autonomously with minimal user intervention 
  • Improve robotic navigation while capturing 3D point clouds to create 3D digital twins 
  • Capture both static and mobile scans during the same scan mission 
  • Repeat scan missions autonomously for up-to-date project progress and site changes 
  • Use GrandSLAM technology: LiDAR SLAM, Visual SLAM, and an IMU for reality capture and autonomous navigation through complex environments 

User Interface

The BLK ARC comes with access to an easy-to-use browser-based user interface, allowing you to plan scan paths remotely using existing drawings or BIM models of your building, including large and complex spaces. This saves time and allows the robot to scan complex or hazardous environments while remaining in a safe location. 

The UI enables you to: 

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


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.
