The Romo Robotic Pet roves your home on a wheeled base, carrying your iPhone or iPod Touch from room to room.

“Romo is a curious digital creature who lives in your phone and explores your world on his roving base,” says developer Romotive. “Just download the app and dock your iPod Touch or iPhone. Let him explore your world and snap photos of what he sees. Program him to respond and adapt to his environment. You can even control Romo remotely via web browser or other iOS devices – from anywhere in the world.” Your kids can train him to recognize faces, dance to music, or chase a ball. You can also “invite friends and family anywhere in the world to control your Romo remotely while streaming 2-way video and audio,” Romotive adds, and parents can “go room to room to say good night while away on business.”

It can move about at a top speed of one foot per second, and runs around for two hours nonstop on a charge. “You play. Romo learns.”
