Stand by the Double Robotics booth at the Macworld trade show, and you hear the same thing over and over again as people walk by:
"I would never have to leave the house again."
"I would never have to go to the office again."
That's the reaction to the Double, a remote-controlled robot stand that will be available this spring for $2,000. Built by Double Robotics, a Sunnyvale, Calif., company, the gizmo is essentially a stand for an iPad with two wheels at the bottom.
Insert an iPad on top of the Double and download the company's app on that iPad and another iOS device. Use the second iOS device to steer the Double from miles away. The robot uses sensors and gyroscopes (much like the Segway) to stay balanced.
