Roomba is a low-cost robot produced by iRobot. It is intended to be a commercial cleaning robot, however with little to no modification it can become a powerful educational/hobbyist robotics platform.
Contents
Sensors & Actuators
The Roomba comes with these basic sensors:
- Four IR based cliff sensors
- Two bump sensors
- One wall sensor
- A top mounted IR sensor. Used by Virtual Walls, Docking Station, and Remote Control
- One Dirt Detector (acoustic impact). Some Roombas have two.
The Roomba is sold commercially as a mobile vacuum cleaner, thus it also has these actuators:
- Two wheels drive with differential drive
- One main brush motor
- A side brush motor
- A Vacuum motor.
Communication protocol
The Roomba proprietary Serial Command Interface is available here: iRobot Roomba Open Interface (OI) Specification.
Hacking the Roomba
To interface with the Roomba Serial Port you need a USB - Serial adapter (for 0-5V signals, NOT RS232 levels!). You can find the schematics and the PCB layout of such an adapter here: USB - Serial adapter (iRobot Roomba variant)
You can also find other schematics on net as well as ready to use cables: Roomba-serial, Roomba-USB or Roomba-bluetooth.
Schedule
If you need to move a Roomba from the lab, you should first ask to Andrea Bonarini, and then fill in the table below.
