Robots are going to make our homes smarter. A premium robot that can get things done around your home can cost a bit of money. But there are plenty of fun projects you can try at home for cheap. The below video shows how you can use an LG G Watch running Android Wear to control a robot.
This is an omni-wheel robot with 3 wheels. The watch sends commands to the paired phone using MessageAPI. The phone then sends those commands to the Socket.IO on the Raspberry Pi. You can find out more about this project here.
