I am a sucker for remote controlled toys and lately I have checked out a bunch that are controlled by the iPhone. A new RC toy has turned up called the TankBot and it is from Desk Pets. Desk Pets is famous for making little RC toys and other things that you can play with.
The TankBot has three play modes. It can navigate mazes, free roam, and you can fully control the device using an app and the iPhone or an Android device. The TankBot is powered by an integrated rechargeable battery.
Charging is done with a USB port on your computer. The little toy makes sounds and each color has its own frequency of operation allowing for play with several at once. The bot is available now for right under $25.
