Guided by GPS, the robot makes its way up and down rows of vines or trees, spraying the crops along either side of itself as it goes. It utilizes a combination of LiDAR sensors and cameras to detect and identify any obstacles in its path, slowing down or stopping as necessary.

Prospr additionally has a pressure-sensitive front bumper, which triggers the bot to stop if it encounters significant resistance. If all else fails, there's also an on-vehicle emergency stop button.
