What do I need to buy to add Bluetooth to Arduino Uno?

This can provide "slave" bluetooth. http://www.dealextreme.com/p/jy-mcu-arduino-bluetooth-wireless-serial-port-module-104299?item=8

You need to have a "host" like your Android phone or computer.

How can I use my Samsung Galaxy 7.0 Plus tablet to control robots thru Bluetooth?

Write, or obtain, an app for your tablet that takes control inputs and sends them via the bluetooth/serial link. You could try something like Arduino Commander (http://anettosoftware.co.uk/ac.php), if you didn't want to, or didn't know how to, write something yourself.

I'm afraid to buy anything from Deal Extreme because I found out that they are in Hong Kong. I bought some items from Sparkfun.
