Whether you need a robotic companion to remember the names of people you meet at parties, an algorithmic pal to help you stomp on the crispy leaves in autumn, or just a really, really big 'bot for no particular reason at all, Small Robots is your spotter's guide to the wonderful world of robotic friends.

They bring tea, complain in restaurants, retrieve lost balloons, but they also tackle more serious problems: mental health, disability, discrimination and grief, and will, when called upon, fiercely defend the marginalised and oppressed.

This collection of one hundred of the best and most beloved 'bots delves into the functions, features, dimensions and backstories of these wonderful but often bafflingly obtuse creations. Discover how they perform their all-important tasks in the world of their large human friends, revealing how acts of kindness can be achieved in the littlest and most unexpected ways.
