There are all kinds of nifty spy gadgets you can buy to get your sleuth on, but if those products aren’t doing it for you, Sony has something new that you may want to check out. According to a site called Siliconera, Sony has filed a patent for a remote-controlled car that would use the PSP as an interface.

It’s equipped with a camera to feed video to the PSP and users would be able to upload the footage to a website if they want. But that’s not all. The patent mentions an augmented reality racing game. The game recognizes real objects as elements in the racing game, so basically, you build your own track from stuff ou have around the house.

South Korean telecom company KTF just announced a cleaning robot that can be controlled by a 3G cellphone. The Roomba can’t do that, now can it? The robot is called the CW100 and is the result of a collaboration with Microbot.

It’s a “smart” vacuum, like the Roomba. It can be controlled by phone, which the Roomba can’t, unless modded to do so. It uses an onboard video camera to send live images to the mobile phone, so if you see an untidy spot, the user can remotely control it using the keypad and clean it up.

To promote their various laptops and showcase their digital sign technology that uses real-time data over the Internet, Toshiba tested an interactive digital billboard in Tokyo last weekend. YouTube users and passers-by with mobile phones were able to play video games against each other and take a short break from the rigors of city life.

The games were played on a digital billboard above the entrance to the Yodobashi Camera superstore in Akihabara. The games are basically mini-games and involve up to six players in a 90-second race to paint squares on a grid and hunt for Toshiba’s cute and cuddly Pala-Chan mascot. Mobile phone players used their number keys to control the game, while YouTube players on computers used the arrow keys on their keyboards. Videos below.

Over at Evil Mad Scientist there is an easy DIY project that will make cleaning fun and better yet, it might encourage your slacker kids to help out a little. Hit the link if you want to see how simple it is.

Basically an unprinted circuit board is attached to an RC car of your choice which is used to mount a dust mop. After that it’s just cleaning and play. This has to be dirt cheap to produce in a factory. Remote controlled cleaning would sell a bunch of cleaning supplies. They got everyone to buy swiffers after all. Check out the video below.

I don’t care who you are, it doesn’t get much funnier then the elderly treating their wheelchair like a hot-rod and just gunning it. Previously, if you wanted to see the geriatric in racing form, you had to play slot car racing grannies.

Thankfully, someone has expanded the premise to include an old woman in a grocery store, with slippery floors and plenty of canned goods to crash into. The handicap ramp should provide some airborn Dukes Of Hazard moments too. It will cost you about $36. Good fun. It will give you something to think about the next time you’re in line behind an old woman with a change purse.
