The QBotix Tracking System rethinks two-axis tracking in an effort to bring the cost down to what solar project developers pay for single-axis trackers.

Instead of having the hardware to adjust the angle on every solar panel, QBotix engineers created a traveling robot equipped with the motor needed to change the angle. Like a small train, the robot drives along a track a few feet off the ground placed along the edge of solar panels and makes adjustments.

It’s designed so that one robot can service 200 panels in 40 minutes, the time it takes the sun to move 10 degrees. The track can be a simple loop or navigate turns and hills, according to QBotix CEO and founder Wasiq Bokhari. A magnet on the robot allows it to locate a panel mount, where it can attach its motors to make the adjustments.
