The RCS consisted of a Remotec Andros Mark VITM with cameras and lights, modified to incorporate a gamma detector, a smear sample pad, and a deployment station, which was designed to manage deployment of the Andros hardware as it was lowered into the tunnels. The specific tasks for the Andros hardware included traversing the entire length of the tunnels to be inspected, collecting video footage, documenting the physical condition of the tunnel, collecting gross gamma readings during the entire survey, collecting limited smear samples, and returning safely for extraction from the tunnel.
