We've long expected LG's latest flagship phone would be making the rounds in Barcelona at Mobile World Congress. But here's something we didn't expect: The G5 modular, so you can pop the battery out of a compartment on the bottom end and slot in accessories.

Tuck the Cam Plus into the bottom of LG's G5, and you'll outfit the phone with a dedicated shutter button, and a wheel that offers granular control while you're zooming.

You'll use your phone to drive the robot, and it'll scoot around your home feeding you audio and video of whatever it sees. Duck into pet mode, and you can chat through speakers and fire a laser pointer to keep your pets (or roommates) entertained. There are potentially hours of fun to be had here -- and I imagine the security benefits could be useful, too.
