To that end, the internals are stored as indicated within a watertight enclosure, which is currently made from cast acrylic (also known as poly(methyl methacrylate) or PMMA) and will be manufactured from aluminium in the future. Some PETG (polyethylene terephthalate and glycol) components are also used as non-watertight elements, such as the thruster and payload mounts. “It is worth noting that the aluminium hull won’t have any significant effect on mission runtime, be it in terms of increased weight or reduced heat build-ups, but in addition to functioning in warmer waters it will also be able to go deeper and use newer payloads, like aluminium diving lamps that are rated to 300 m depths,” Arteaga notes. Stability comes largely from the thrusters, but their symmetrical arrangement around the hull (and the placement of the battery in the middle) ensures good balance of mass and buoyancy across all orientations. For modularity, the hull’s watertight enclosure is surrounded by a frame that includes rails for attaching external payloads. These rails enable multiple different sensor arrangements, with one of the most complex including three cameras mounted on arms extending in different directions from the AUV’s undercarriage and one camera on the top side, with further payloads on the sides (as tested by uWare for a project requiring multi-angled underwater vision). Computing edge Keeping the uOne small and easily oneperson portable has limited the quantity of computers and processing power that uWare can fit inside, so mitigating heat dissipation has been crucial to avoid thermally overwhelming these systems. The main control board features two computers. A Raspberry Pi 4 (RPI4) is used as the main control and navigation computer, responsible for the execution of navigation and decision arbitration algorithms, while a NVIDIA Jetson
