The Wheelbarrow is a remotely controlled robot designed by Lieutenant-Colonel 'Peter' Miller in 1972 for use by British Army bomb disposal teams operating in Northern Ireland (321 EOD), mainland Britain (11 EOD Regiment) and Iraq. The Wheelbarrow has undergone several upgrades, the latest being the Wheelbarrow Revolution. The most notable feature in this model include the 360 degree arm which can be outfitted with various EOD attachments. The Wheelbarrow Revolution is also capable of climbing stairways.
