The TraxBot Robot

The TraxBot is a tracked mobile robotic platform developed in the Mobile Robotics Laboratory (MRL) at the Institute of Systems and Robotics (ISR) in the University of Coimbra, which has a differential drive system built upon the Traxster II Robot educational Kit extended with substantial components and improvements. The light and robust aluminum chassis is equipped with 2 DC gearhead motors on the front wheels, with quadrature wheel encoders. A flat acrylic structure was added on top of the platform to support a 10” notebook and the three ultrasonic range sonars, as presented.

The Traxbot is a low-cost robot based on open source tools, incorporating an Arduino Uno board as the control unit together with the OMNI-3MD motor driver, which are placed inside the robot chassis. Following this philosopy, the next step was, of course, to add ROS support. The battery pack is placed under the TraxBot and it also includes an Arduino compatible Xbee Shield which enables an easy-to-use Zigbee-based communication interface, enabling easy data exchange between multiple robots or between the robot and a remote unit when no Network infra-structure (i.e., WiFi) exists.
