The company's modular underwater vehicle design — with standardized interfaces across power, data, and mechanical connections — allows rapid reconfiguration for different missions.

Ulysses brings machining in-house to iterate quickly, and uses a fully modular architecture where every module shares standardized power and data connectors. Customers can add sensors, swap batteries, or add thrusters in the field within minutes. ✦ AI generated

On the mechanical side of the house, we've brought machining in-house specifically so that we can design something, make it the next day and see if it works. We have had a lot of customer input that the modularity is important to them and what it enables is that they can add the sensors they want. They can configure in the field to add more battery or more maneuverability with extra thrusters etc. Each one of our modules has a standardized interface. We have two power pins here and a data connector here. Every single module has that loadout so they can all connect together. They're all getting full battery voltage and full data connection across the entire vehicle. Every single connection is standardized. If we want to go down and survey something with the multibeam echosounder or sonar systems, we can just strap those to the front of it and have that capability within 20 minutes.

5:02specifically seawater. It wants to destroy anything robotic and it's corrosive. We immediately [music] discovered that operating in the ocean works very very differently. The ocean is always trying to kill you and flood whatever you put inside it. On the mechanical side of the house, we've brought machining [music] inhouse specifically so that we can design something, make it the next day and see if it works. We have had a lot of customer input that

5:46They're all getting full battery voltage and full data connection across the entire vehicle. every single connection is standardized. If we want to go down and survey something um with the multi-beam echo sender or sonar systems, uh we can just strap those to the front of it and have that capability within 20 minutes. That's the beauty of the modular system. Real world data is always better and always more accurate than [music] any

6:13sort of simulation you can do. When going into space, it's a lot harder to access space [music] and just go up to test and get your real world space data. It's not the case with the ocean. You know, most of the planet [music] is covered with it. So, we have this advantage where if we can get something that's ready to go in the water, we [music] can get the best possible
