PJBot_V3

Let's Make Robots Robots

This is PJBot version 3.
The brain of this Bug is an Arduino. Now, it only go rolling and avoiding obstacles that it detects with 2 led's and 1 IR receptor.

For now it have:

* Base - made with the plastic box of a roller blind
* Arduino
* Proximity sensor - 2 IR LEDs and an IR receiver
* Driver for motor
* 2 DC Motors
* 2 wheels - made of bottles and fish food caps, and hot glue
* 2 collision sensors - which are not connected


Ideas:

* Use an I / O expander controlled by I2C to connect the sensors and driver
* Install a RF12 transceiver
* Install an LCD also controlled by I2C
* Install a wireless camera
* Thinking of a way to use a old mouse to learn the speed and direction.
* ...


The code still has some problems and need some improvements.

I am waiting for your reviews and comments.

Great scratch built
It looks like you have a solid base to work on here. Lots of free space on your proto board<o:p></o:p><o:p></o:p>Good luck with the interface to a mouse. I tried to interface a mouse with a PICAXE but gave up. It looks simpler with the Arduino http://www.arduino.cc/playground/ComponentLib/Ps2mouse<o:p></o:p>

I already connected an mouse
I already connected an mouse to an Arduino in the past. The problem is more mechanic :wink: How to adapt to the wheels?
