Study of the Design of an Explosive Ordnance Disposal Manipulator for Small Unmanned Ground Vehicle

In this paper, mechanism design of the explosive ordnance disposal(EOD) manipulator for small unmanned ground vehicle(SUGV) is presented from the conceptual to detailed design. EOD manipulator has been widely developed in the world due to the growing threat of the improvised explosive devices at war. It has distinctive characteristics, such as small size and high loading performance, compared to the industrial manipulator which is fixed on the floor. Design of new EOD manipulator must take into account various functional requirements and constraints simultaneously. We focused on developing the EOD manipulator that has suitable size for the SUGV and maximum 15kg payload capacity. Design approach taken in this paper is based on axiomatic design procedure and comparison among many possible candidates of each joint structure to obtain appropriate entire structure of EOD manipulator.
