Researchers at the MIT Media Lab have modified an Aibo robotic dog from Sony so it monitors your daily food intake and exercise levels and nags you to stop pigging out and get off your butt to exercise. It’s connected by Wi-Fi or Bluetooth to your bathroom scales, a pedometer, and a PDA in which you list everything you eat. When you ask “How am I?” it reacts. If you’ve been watching your diet it jumps up and down, wags its tail, plays exciting music, and flashes LEDs. If not, it makes you Sweat to the Oldies and poops on the floor. Just kidding. Actually it moves lethargically and plays low-energy music. It’s like living with Richard Simmons without the whining and high maintenance.
