Step 2: Android G1 with serial output enabled

G1's do not ship with the ability to send serial commands out of the USB port and there is no native option to enable it. If you are an advanced Andro...

Step 3: Install the Android Scripting Environment (ASE) with Python

The scripts we'll be using to create an open socket connection on the phone and send commands out is written in Python. To run this on the G1 we'll ne...

Step 8: Run the whole process

You should be able to connect the HTC USB board to the phone, fire up the cellbot.py file in ASE, and open a terminal sessions into the phone. Type "H...

Intro

Android G1 Serial To Arduino Robot

Learn how your Android cell phone can control a robot using an Arduino board. The phone takes commands via telnet from another phone or a PC, so you can control the robot remotely. This project will not otherwise modify the G1 so you can continue using it as your normal phone after undocking it.

Why?
By using cheap electronic components such as Arduino boards, you can pair them with your $400 phone to make an awesome robot. It would cost hundreds of dollars to add GPS, LCD's, motion sensors, wi-fi, cellular connections, speakers, and more to a hobby bot, but your phone already has these!
