US Startup Origin Develops OG-1 Interior Construction Robot for Drywall Finishing

Targeting drywall taping, sanding, and painting in interior finishing, US startup Origin has developed the OG-1 construction robot. Moving away from humanoid form factors, the system utilizes a weighted three-wheeled base, lifting platform, and robotic arm designed to fit through standard doorways and reach up to 14 feet (around 4.3 meters). Technically, OG-1 relies on real-time force control to maintain consistent surface pressure and a 360-degree vision system capable of identifying 200 common construction site objects, eliminating the need to cordon off active work zones. The underlying software, designated the Construction Action Model (CAM), uses a three-tier architecture to handle sequence planning, trajectory strategies, and real-time motion adjustments. Training incorporates field sensor data, expert laboratory demonstrations, and high-fidelity simulated environments. On-site operations are managed by an existing crew member acting as an operator to handle spatial scanning, tool changes, material refilling, and maintenance. Origin offers the system on a usage-based rental model and claims overall shift efficiency reaches three times that of manual crews. At the time of reporting, the company maintains four operational units with approximately 100,000 square feet completed, with plans to expand its capabilities and fleet.

Key takeaways

• OG-1 integrates a three-wheeled base, lift platform, and arm to reach 14 feet for interior taping, sanding, and priming.
• The system uses real-time force feedback for surface pressure and 360-degree vision identifying 200 site objects in cluttered spaces.
• A three-tier Construction Action Model manages task sequencing, trajectory planning, and real-time surface corrections using multi-source training data.
• Provided via a usage-based rental model, the robot operates alongside on-site crew members, with the firm claiming triple manual shift efficiency.
