the robot up to the floor? she is spraying a polyurethane foam which has been used in industry for years to retrofit insulation. so what can a robot do in this environment that a person can't do, for example? so, what we've actually done is create jobs for robots in an industry which didn't exist before. these robots actually navigate very small environments which are far too dangerous to send a human. and i notice you're controlling this all from a video game controller there. i am, everything can be done from a game pad. it does look like a game, looks like a lot of fun. what are you seeing on your screen, there? what i'm seeing is my virtual aiming arrow which shows me where i'm spraying. i've also got my spray pattern which i'm running through here to get the job done. so it's nice and easy, nice and safe. this is obviously a mock—up here. will this work in everyone's homes? what we're looking for is two things. suspended timber floors, and floors that have less than 20% moisture.
