If the idea of sentient robots one day invading our homes sends luddite chills down your spine, do not read further — because that day is one step closer. Keecker is an Android-powered robot that follows you around your home, projecting content from your smartphone, or directly from the device itself onto your walls. You can use it to play games with your phone as the controller, watch video projected onto the walls, listen to 360-degree immersive sound controlled by an app on your smartphone, Skype with friends while walking around your house, or use it as a nanny-cam by telling it where to go in your place. In addition to entertainment, you can also use it as a home security robot — and though it won't shoot lasers at intruders — it can monitor air quality and let you check in on your home remotely. Since it is completely wireless, has a built-in battery that lasts up to a week, and can run any Android app out there, the possibilities are pretty much endless.
