When Robert Oschler, a programmer, leaves his home, he knows it is secure.
And if he ever has cause for concern, he can open his laptop and survey the house through the eyes of his watchdogs.
“I don’t have any pets. I just have pet robots, and they’re pretty well behaved,” Mr. Oschler said. “Fortunately I’ve never logged in and seen a human face.”
His robot, a modified version of the Rovio from WowWee, has a camera, microphone and speakers atop a three-wheeled platform. From anywhere with a Net connection, he can send his robot zipping around the house, returning a video signal along the way.
“As creepy as it sounds, you could even talk to the guy and say, ‘Get out of there. There’s nothing valuable. I’m calling the police,’ ” he said.
For all its power and ability, the Rovio is usually found in a store’s toy section for about $170. Other robots from toy makers, like Meccano, are there as well. Outfitting a house with a fleet of robot guards is no longer just for those with the wealth of Bond villains.
Home security is blossoming for toy makers who can match the technical power and flexibility of the computer industry with the mass-market prices that come from large production runs. Low prices are a trade-off, however, because many people find that the reliability of the lower-priced robots is adequate for home experimentation but far from ready for a task like guarding Fort Knox.
“You should buy two,” said Mr. Oschler, who lives in South Florida.
The off-the-shelf unit is ready to explore after a simple installation involving the computer, but Mr. Oschler added a few enhancements to the software, which he distributes at robodance.com. His version improves the audio and video quality and offers more sophisticated programming options that create routines and paths for the robots to follow.
Mr. Oschler has even wired his robot to a headset that picks up the subtle electrical activity produced by his brain.
“When I tilt my head, the robot goes left. When you do that, it’s a Matrix-like moment,” he said proudly.
