That seems like an efficient approach for a commercial scale version. The form would essentially mirror center-pivot irrigation [1] so you can keep a fixed point for delivering energy, water, fertiliser etc and cover larger circular patch with a series of smaller linear robots. Each span could also be modular to adapt to different sizes as suitable for the landscape.
