ratb0t

This is the ratb0t, he has a nervous behavior and remainds me of a rat.. :]

I´m using an Arduino Diecimila to control the steering servo and the traction motor.

The XBee module receives data from another Arduino, this one has a wii nunchuck controller attached.

Next Step: make it autonomous

Update:
I forgot to tell a little story about this little and nervous fellow.
One day my mother told me she had one hair-removal thing broken (Braun Silk Epil brand ), and she said that she would bring it to me so that I fixed it.
Of course I accepted, but I must confess, I never ever tried to fix it :)

This made me think a lot on how could I twist it and use it to give life to a robot.

The most difficult part was to transform the front blades onto a wheel, I did it using pieces of bike air-chamber, rubber and hot glue.
I like the final result and it works quite well!

Shame on me because I didn´t document the building proccess.. I will try not to repeat it :)

If you have some interesting mechanical broken items I accept them :)

Farrusco RC

I wanted to keep working with the XBee modules, and I thought it would be cool to control Farrusco.

So, first I used 2 potenciometers and assigned one to each motor.. and then I used a nunchuck controller.
Both require a learning curve and it’s only after a while that you start to feel the touch  :]

This is the code I´m using to control the robot with the Nunchuck


Serial Comunication between Arduinos – With Wire & Wireless

— please check an updated code sample on the following post —
http://lab.guilhermemartins.net/2013/08/01/new-basic-arduino-serial-communication/

 

I´ve created this example to make two Arduinos talk in a simple and clear fashion.
You will see below an example with wires, and another one without wires.
