When my daughter was 3, she was eating Cheerios and spilled some on the table. So she swiped them onto the floor. I said, 'Darcy, what are you doing?' She said: 'Don't worry, Daddy, the robot will get it.' I didn't know whether to be horrified or proud. It was this idea that homes take care of themselves and robots are part of that.

At MIT, in Professor Rodney Brooks' lab, I was involved in a project, led by Anita Flynn, to build robots using techniques similar to those used in building silicon chips. We got some silicon micro-machined motors to move a bit, but this didn't lead to an actual product.

You make your first album, you make some money, and you feel like you still have to show face, like 'I still go to the projects.' I'm like, why? Your job is to inspire people from your neighborhood to get out. You grew up there. What makes you think it's so cool?
