A rendering of NUI transitting with manipulator and workspace tucked behing a low-drag cowling. NUI will be able to reconfigure itself underwater and in situ between the low-drag mode shown in this rendering and the manipulation mode shown in the previous two slides.
A low drag configuration is critical for enabling NUI, which carries its own batteries, to transit long distances (kms) between a host vessel and work sites that might be in otherwise inaccesible locations beneath glacial ice. In sea ice, a transit capability means NUI can perform mapping and sampling/intervention on the same mission, and retain enough reserve energy to transit back to the vessel for recovery.
NUI will reconfigure itself by rotating its "forehead" onto its "back" and then rotating the arm out of its stowed horizontal position into a more typical vertical position. A "visor," shown here in conceptual form, will cover the "mouth" area in a later iteration.(Casey Machado)
