Roomba Robot Garden Dog

Roomba Robot Garden Dog is one of those Boston Dynamics mechanical robot dogs that can move around performing all kinds of actions. This particular version has been custom made to water your garden plants. Here’s how it works:
A recharging weather proof kennel houses your Roomba Robot Garden Dog, with the dog only emerging at preprogrammed intervals, its main function being to water your plants.

To do this Roomba Robot Garden Dog carries a small water tank on its back which is topped up when required by returning to the recharging kennel. To water the plants, Roomba Robot Garden Dog simply lifts one of its back legs and delivers a jet of water in the same manner of a real dog peeing against a lamp-post. The water can be adjusted as a pulse, single shot, continuous jet or gentle spray. Once the plants are watered, your Robot Garden Dog trots obediently back to its kennel, unless it’s a deluxe model in which case it wanders around scanning for unwelcomed visitors.

It does this because Deluxe Roomba Robot Garden Dog doubles up as guard-dog.
In this case the water jet is pressurised, infused with a dayglow dye and directed accurately towards any intruder.
