I have said before that the future of robotics and in general is telepresence. If you aren’t familiar with it, think of it as a way of sending a robot in your place. You can literally be in more than two places at the same time, and the number of places is limited to how many of these things you can control.
Double Robotics showed off their robot at CES 2014, which has a unique ability to balance on a cylinder. The top is a stand that is made for an iPad, and since it has a front-facing camera, it can see you. I have noticed that a lot of telepresence robots have this look to them: a big pole with wheels.
The company recently announced a way to recharge the robot with a charger that will come with it. I believe it is made to simply park next to the robot and charge inductively, like a Powermat. It is available for purchase for a price of $2,499, and you can find out more about the company here.
