Meet the QBii: a versatile robot that can carry your things, mop your floor, and climb stairs to get things done in your home. It can carry up to 50lbs of load and tow up to 200lbs. It comes with various add-ons to take on new tasks, such as sweeping your floors. This robot has an expansion port that lets you attach additional sensors.
You can control your QBii with your smartphone or tablet. You get a path editor to create and run customized path. The Control app also lets you teleoperate the robot. Since the robot is expandable, you can use it for your own complex projects. This project is getting funded on Kickstarter at this time.[where to get it]
