The palm-size device (measuring 128mm x 96mm x 80mm and weighing 330 grams) won't likely give you a deep-tissue massage. But it claims to stimulate the parasympathetic nervous system by gently touching and vibrating its way around your body. WheeMe also claims to stimulate the nerve endings below the surface of the skin, which may increase the release feel-good endorphins.
Sensors determine the slope of your back, so the robot massager can shift direction and keep rolling rather that falling off your body.
A slew of massagers were on display at the event, including an array of portable battery-powered massagers from Breo, such as the iDream 3 Eye and Head Massager --designed for computer-weary eyes. Breo also launched its iNeck Massager, which relaxes the cervical vertebrae by kneading the pressure points on the neck. Watch the robot in action: http://www.youtube.com/watch?v=hJAUTzk4GFM
