From raw LiDAR scan to paintable walls in seconds — onsite
π¨π€ #PACO (Les Companions‘ autonomous painting robot) cuts painting time by easily getting instructions, from the technician onsite.
The process looks simple:
1οΈβ£ Scan β 2οΈβ£ Decide β 3οΈβ£ Let Paco Paint
But lots happens under the hood to make it “simple” by extracting:
π§± consistent wall surfaces
π clean geometric boundaries
πͺ window and door openings
π« exclusion zones (holes, obstacles, protected areas)
π stable, bounded entities usable for planning
This requires:
π LiDAR-based SLAM for coherent spatial reference
π§© fast & robust planar segmentation under real-site noise
π plane merging and topology reasoning
βοΈ constraint-aware boundary extraction
Today:
ποΈ 8 real deployments
π¨ 15,000+ mΒ² painted autonomously
π France2030 Automated Machine award
Turning raw 3D points into geometry a robot can act on β and watching it perform on real walls β is deeply satisfying.
Raw 3D data in. Real-world action out. Thatβs Perception4D.
