Analysis and Design of a Novel Mini-platform Employing Vibration Micro-motors

This paper presents the analysis and design of a novel mini-robotic platform that is able to perform translational and rotational sliding with sub-micrometer positioning accuracy and develop velocities up to 1.5 mm/s. The platform actuation system employs vibration micro motors. The dynamic model of the platform and of its actuation system is presented, and analytical expressions are derived which provide design guidelines for the platform. Simulations are performed which verify the analytical results and demonstrate the platform capabilities. The platform design is simple, compact and of low cost. Also the energy supply of the mechanism can be accomplished in an untethered mode using simple means such as single cell batteries.
