The robot, if you can call it that, is only 15 pounds. It adjusts height so you can communicate naturally at either standing or sitting height, and moves forward, backward, and turns as you control it from your own iPad or iPhone at a remote location. When not in use, two kickstands ease down from the cylinder between wheels, allowing Double to conserve power and wait for the next rider. If you’re shocked that hardware this polished and sophisticated could be created on a typical Y Combinator budget of $20,00-40,000, join the club. But while the company has not received any other funding, and the Y Combinator money has helped, co-founder Marc DeVidts told me that there’s been other sources of income.
