Strawberries would be a worst-case for this design. The plants are low and spreading, and weeds tend to start under them and then pop up through -- so it's the tall plant that's bad and the short one that's not only wanted, but when the fruit are setting, very delicate. Little slanty robot wheels would make jam out of the berries.

Also, typically your rows of strawberries are long and separated by only a few inches, so the stakes, or croquet wickets they are selling wouldn't work. There wouldn't be room between the rows of wickets for the robot to move.
