Nexys

Summary

The Exyn Technologies Nexys is a 3.1 kg modular LiDAR mapping sensor that captures 3D point clouds when mounted on drones, ground robots, vehicles, or carried by hand. It covers three documented subtasks within quality assurance and site safety: 3D scanning and point cloud capture, BIM-to-field comparison, and air quality monitoring via environmental sensing. Nexys has shipped since February 2024 with four confirmed deployments across four countries; construction is a secondary market for Exyn, with distribution through channel partners including KOREC (UK), Keystone Precision (US), Measur (Canada), and C.R. Kennedy (Australia).

Air Quality and Dust Monitoring 3D Scanning and Point Cloud Capture BIM-to-Field Comparison (Scan-vs-BIM)

How it works on your site

Air Quality and Dust Monitoring

Nexys integrates environmental sensors (gas, leak, gauge) alongside its LiDAR capture, collecting air quality data during routine mapping passes without requiring separate personnel entry into confined or hazardous spaces.

3D Scanning and Point Cloud Capture

Nexys captures 360-degree point clouds using a gimballed LiDAR sensor at up to 1,920,000 points per second, outputting LAS, PLY, XYZ, and E57 formats. In autonomous aerial mode, the onboard SLAM engine navigates GPS-denied environments without pre-mapping or external communications. Scanning routes are programmable for repeat passes supporting digital twin workflows.

BIM-to-Field Comparison (Scan-vs-BIM)

Nexys point cloud data can feed into BIM comparison workflows where as-built conditions are checked against planned models. The base variant carries a vendor-stated +/- 10 mm accuracy specification; the Nexys Pro claims +/- 5 mm. KOREC field measurement recorded 5 to 20 mm at control targets, indicating real-world range varies from the spec sheet. The scan-to-BIM pipeline described in Exyn's construction marketing is not documented with any BIM software integration, LOD requirements, or working comparison workflow.

Operating weight 3.1 kg with battery (Nexys Pro) 2.4 kg without battery. Weight may differ for standard Nexys (Velodyne sensor).

BIM/CAD Point cloud output (LAS, PLY, XYZ, E57) Vendor describes scan-to-BIM comparison workflow and Trimble Reality Platform integration; no independent field validation found.

Fleet management Multi-robot swarm coordination via ExynAI Swarm support confirmed by independent press (2018) and vendor SDK docs. Specific coordination protocol and tested fleet sizes not publicly documented.

Scan rate and accuracy Up to 1.9 million points per second; 5 mm accuracy at 1 sigma Accuracy figure is for SLAM-based mapping; field results vary with environment complexity and scan speed.

Operator skill No skilled pilot required for autonomous missions Operator defines area of interest; system plans its own path. Specific training duration not documented by independent sources.
