The robot, El-E, is primarily constructed from off-the-shelf components. Its mobile base is an ERRATIC platform from Videre Design, which includes an on-board computer with a Core Duo processor and 1 GB of memory with which the robot performs all its computation. The computer runs Ubuntu GNU/Linux and the engineers have written most of the software with Python and occasionally C++. They also make use of a variety of open source packages including SciPy, Player/Stage and OpenCV.
