CK Greenhouses in Cheshire gave a short demonstration of their robots, which are used to space their plants in both their greenhouses and outdoor mum fields. Here you can see them moving the pots from a pot to pot spacing to a final spacing.   They have a rechargeable battery so can work for 12 hours and use the reflective tape to orient themselves. The grower said that they were relatively easy to program and are a great labor saving tool. Watch the video to see the robots in action.
