Query: Designing a Miniature Wheel Arrangement for Mobile Robot Platforms   In this research report details of design of a miniature wheel arrangement
are presented. This miniature wheel arrangement is essentially a direction
control mechanism intended for use on a mobile robot platform or base. The
design is a specific one employing a stepper motor as actuator and as described
can only be used on a certain type of wheeled robots. However, as a basic
steering control element, more than one of these miniature wheel arrangements
can be grouped together to implement more elaborate and intelligent direction
control schemes on varying configurations of wheeled mobile robot platforms.
