Robots are different from computers. They don't live in their digital virtual worlds, but in our own physical environments, made of furniture, objects, animals and people. Recent robots can now perceive the geometry of this shared shape and learn to behave relevantly in these highly unpredictable environments. I believe one of the future of robotic technology is in the creation of robotized computers capable to offer services adapted to the presence of people surrounding them. This new family of devices will act like attentive partners, offering various forms of augmented reality applications. Through a rapid overview of my own research in robotics during the past 15 years, I'll argue about the relevance of computers that share our own physical and social space.
