  1. iRobotRoomba and the Future of Domestic Robots Dr. Hayden So Department of Electrical and Electronic Engineering 12 Sep, 2008

  2. Rosie of the Jetsons

  3. Domestic Robots • Robots that help us do our work at home • Service robots, home robots, therapeutic robots… • Why do we care? A Robot in Every Home…

  4. Robots today – Humanoid – Asimo Cost: ~US$ 1 million

  5. Pet Robot – Aibo Cost: ~US$ 2,500

  6. iRobotRoomba • Autonomous vacuum cleaning robot • Introduced in 2002 • Detect dirt and clean dirty area automatically • Scheduler • Auto recharge • Finished vacuum • Low battery • Dumb? Smart? Cost: US$ 279.99

  7. Roomba is Dumb and Smart • Dumb • Does not remember contour of your room • Does not remember the spot that has been cleaned • Smart • Auto slow down to avoid hard collision • Pressure sensors • Dirt sensors • Virtual Wall + Light House “guide” Roomba around the house Home base/ Virtual Wall/ Lighthouse IR sensor Cliff Detection Sensors Pressure Sensors Dirt Sensors

  8. Roomba Time

  9. Robot is about Robust Control • A feedback control system • React according to the environment • Read from Environment • Motor Position • GPS, Acceleration/Velocity, Dirt, Heat, Light, IR, RF • Decision Making • Should I move/stop? • How far? How fast? • Reaction • Accelerate, Decelerate • Stop, open arm, close arm, etc

  10. Robotic Vision • Analyzing environment using visible light • Computer vision is difficult • Cheap robots like Roomba can’t do it. • FPGA for autonomous control

  11. Therapeutic Robot • Human Companion • Has psychological therapeutic effects • Example: Paro the seal
