Featuring brand new designs for the chassis and electronics, Seawolf V marked a significant shift in how the club approached building robots. Creating a new robot from the ground up took more time and resources but gave new members the opportunity to learn the entire process and contribute more to the design of Seawolf V.
The frame is constructed of ABS plastic sheets and reinforced with 80/20 aluminum extrusion. This plastic was used because it is easy to work with, almost neutrally buoyant, and creates a more aesthetic frame. As with the past two iterations of Seawolf, the electronics are protected inside a waterproof Pelican case. To reach outside components, like thrusters and cameras, waterproof Fischer connectors are installed.
Seawolf V's custom electronics systems are comprised of two boards, stacked with a high-density mezzanine connector between them. These two boards provide power, thruster control, servo control and sensor input for the craft. This design is a marked improvement from the disarranged multi-board electronic systems used in previous Seawolf designs. The goal of the electronic system in Seawolf V was to reduce cable clutter and produce a more reliable and maintainable design.
Seawolf V uses the same highly modular application based software architecture, designed in Seawolf III and Seawolf IV. New in Seawolf V is a streaming video router called SVR (Seawolf Video Router). SVR allows for efficient handling of multiple video and debug streams which can be monitored remotely over a network connection. Another major new feature is a simulator written in Python using OpenGL. The simulator is used to perform time consuming mission control testing out of the water, allowing us to use our limited time in the water more wisely.
