Summary

About

About Four Growers

Four Growers develops autonomous harvesting systems for commercial greenhouses. The GR-100 travels crop rows and uses a robotic arm calibrated with four stereo cameras to detect fruit, judge ripeness and pick tomatoes, bringing perception, manipulation and crop handling into one mobile platform.

A fleet dashboard gives growers remote visibility into robot operation and harvest activity. The same cameras and sensors generate fruit counts and yield heatmaps at intervals down to three metres, linking harvesting with plant-level production analytics. Four Growers rates the system for continuous operation, ripe-fruit precision of 98% and throughput up to 43 kilograms per hour for small tomatoes, with performance dependent on crop and configuration.
