I can see a lot of possibilities for these.
Computers and satellites drive the big ones down the field so why not a fleet of small ones totally autonomous working away.

Going to need an IT credit to farm in the future with some electronics training too I guess.

Agriculture has a reputation of being stuck in the past. In reality, for farmers, their workplaces are a fertile testbed for innovative technology – they were among the first to embrace commercial drone use, and autonomous vehicles that could work effectively (and safely) in confined areas of farmland. Among the latest developments in agri-tech are small, farming robots that can improve crop yield and reduce farming’s impact on the environment.

Customisation of the robot allows it to complete different tasks. The base robot Jack, which wave unveiled at WIRED Live, can be transformed into Dick and Harry. The seeding boom, which can place seeds in the ground at the optimal spacing and depth, is three metres in length and makes the robot “Harry”.
