Introductory
This series uses the spindle driven method to reduce the cost of diving these robots over paper - smooth surfaces. All of the robots in the series feature a common plug-in interface so that the control boards may be interchanged or be substituted by student or hobbyis designs. Furthermore, by adopting the common interface, experimenters and designers have a predictable platform on which to build their own sensor and control arrays. These units are available also as pre-assemblies under the FA prefix.
