When they are available, a life like robot dog and cat - perhaps more than one, would be great - able to walk and go up to a resident who is sitting, and put their head in their lap to be stroked. Residents who don’t like dogs or cats could wear a bracelet tuned to keep the robot away from them. Like robot cleaners and mowers, they would be programmed to keep a distance from anyone on their feet, to avoid accidents - just be mobile when people are sitting. The cats could even purr!
People in homes should all have access to and be encouraged to enjoy the garden, ideally they should all have sensory areas and no poisonous plants. They could help by pulling up weeds and dead heading, and perhaps planting some annuals in the spring, but it would need a member of staff or experienced volunteer to always be around. Washing up would just mean loading a dish washer, probably not practical to let residents in the kitchen. I expect many (women) would enjoy the occasional browse around the shops - but would have to be accompanied. Suitable man/woman power is the problem if there are no family/friends around.
