Our Summit XL is used for applications in the field of Rescue Robotics. We are specialized on software development in the field of sensor processing. Therefore we need an easy to handle and robust robot platform.
This year 2014, we scored the second place (Team AutonOHM) at the RoboCup German Open with Summit XL: http://www.robocupgermanopen.de/en/results/major/rescue
Summit is very suitable for our application because of the high mobility and wheel kinematic and is modified with some additional mechanical parts and sensors for perception.
