The Saga Robotics Thorvald is a greenhouse robot by Saga Robotics, priced at $80K-$130K. It is commercially available and deployed on farms worldwide. Compatible crops include strawberries, raspberries, blueberries.

Thorvald by Saga Robotics is a modular autonomous robot platform that uses UV-C light treatment to kill fungal pathogens on strawberry plants, eliminating the need for chemical fungicides. Operating at night when UV exposure is most effective and safe, Thorvald navigates polytunnel rows treating plants with calibrated UV-C doses that destroy mildew, botrytis, and other fungal diseases. The platform is fully modular, accepting different tool attachments for spraying, data collection, and crop monitoring. Deployed across UK and European strawberry farms, Thorvald has demonstrated 50-80% reduction in fungicide use while maintaining crop quality.
