Kobuki Turtlebot II. User’s Manual
1. Robot description
Kobuki Turtlebot 2 is a low-cost mobile research base designed for education and
research on state of art robotics. With continuous operation in mind, Kobuki provides
power supplies for an external computer as well as additional sensors and actuators. Its
highly accurate odometry, amended by our factory calibrated gyroscope, enables precise
navigation.
This robot is a compatible replacement for the iRobot Create. Although most of the
accessories are fully compatible, be careful when plugging any device from the iRobot
version to Kobuki version, because the connectors pin-out could be different.
