Group 18+.

The iRobot Roomba is a great platform for robotics. The Roomba has a serial interface that accepts commands for controlling and diagnostics. The EZ-B has hardware support for the Roomba, and the EZ-Builder software has controls for the Roomba also. In this instructable, I'm going to walk you through how to remote control your roomba from the computer over a bluetooth connection. Also, you may add sensors or a camera to the roomba to turn it into an even smarter autonomous robot.

In this instructable, I attach a wireless camera to the roomba. This allows the roomba to follow colors (Red, green, or blue) or motion.

Step 1: Connection Cable

The iRobot Roomba uses a minidin connector. The specific model that the roomba uses is a little difficult to find. So a great work-around is to use a regular PS/2 mouse or keyboard connector. The little tab on the inside of the plug will need to be removed first.

Only two wires are required to connect to the roomba from the EZ-B for minimal use. The two wire configuration will only transmit, not receive. But for most uses and in this example, it is the easiest.
  1. Take the PS2 connector apart
  2. Connect the two wires to the PS2 connector according to the attached image
  3. Reassemble the PS2 connector
