The robot is happy with messages on twitter :)

Guardian Robot - standing on the table and tracking messages on Twitter :)
He rejoices in the "merry" and sad over the "sad" messages in your tape.
When he receives a “joyful” message, he raises his right hand and waits for you to “give five” by pressing the switch in your raised hand.
On the contrary, having received a “sad” message - the robot lowers its head and waits for you to hug it by pressing the switch on the stomach.

The robot consists of:
- two serv (one hand controls, and the second head)
- two microswitches
- controls all this Arduino board

Arduin connects via USB to a desktop PC and communicates with an application written in
Processing .
The program checks the twitter feed every minute (using Twitter4j ). Having received the message, the program checks if it is “funny” or “sad” and gives the robot a signal to show the corresponding emotions :)

Robot can be controlled through his Twitter account - http://twitter.com/guardianrobot
You can send him "#highfive" and he will raise his hand :)
or send "#ineedahug" and he will lower his head :(
