This is a must have Arduino Shield if you prefer hassle free wireless Arduino programming.
These guys are running a campaign on Kick-starter around this: http://kck.st/1R3PIWE
The shield costs US$12
and zero shipping charges to any country.
This kick-starter campaign also gives you the option of getting a complete robot kit at US$55 and the kit comes with these items:
4x Geared DC motor
Wheel, Motor positioning Stencil
Arduino Uno Compatible board
The good part is you can build a complete robot that can be controlled by a Smart Phone, and all of this in matter of few minutes.
I did get a chance to get hold of this kit and have found it very good and is exactly same as shown in the video. I am impressed.
To Get The JetPack Shield, Pledge US$12 (only early birds get at US$12, would require pledging US$14/15 later)
To Get the Complete Robot Kit, Pledge US$55 http://kck.st/1R3PIWE
