Shipbuilding is an odd mix of traditional craft work and high-tech manufacturing. Due to the long construction schedules, complex designs, and limited production shipbuilding remains a largely manual activity with pockets of automation. We are applying augmented reality to the task of wiring electrical cabinets in a project called spARky, funded by the National Shipbuilding Research Program (NSRP, www.nsrp.org). The goal of the project is to reduce the cost of installing wires by showing users the end point connections and the desired routing of each wire through the free space of the cabinet. This will replace the historical use of simple wire tables. A handheld tablet computer will show augmented wire model data inside of the actual cabinet. This will enable correct routing and cable bundling with first-time quality and no rework.
