Sub-team presentations took place today to give everyone an update on what each team is currently working on.
Hull design posted a google doc to take data inputs from all teams to organize the so they can finalize the hull design. They require power usage and mass input (over all other values) to move forward. Ideally all inputs will be made by the end of the day so that hull design can proceed as quickly as possible.
Control team is primarily focusing on rudder. They are considering 2 dual rudders or a single rudder. They are leaning more towards singles rudder as there is a lower chance of failure since there are fewer attachments in the single rudder system.
This week they will look further into the torque that the rudder needs to withstand, figure out how to make the rudder waterproof. When the hull design is finalized they will begin modeling the rudder on solidworks.
The power team is leaning to mono-crystalline solar panels as they are the most efficient option (15-24% efficiency), and have the greatest power output at 1060 watts. They are also looking at a wind alternative that would produce 400-600W, with a cost of $400-$700. Currently a 9 SP4-144 solar panel system is found to be the most efficient model giving 4.9m long, 1.49m wide hull design.
The power storage is essential as the sun is not 100% reliable and the boat must be able to deal with fluctuations over time a long periods time. The power team is looking into a variety of power storage options including multiple type of batteries, thermo electric generators, and hydrogen fuel cells
Power distribution is looking into a variety of systems while considering size, voltage, and programmable ability. They are with navigation to look more into distribution.
Over the past 2 weeks navigation has looked into power consumption, weather conditions (wind and waves), tracking, boat traffic, and prioritizing land mass collisions. This background research allows them to now look into how they will connect their system to motors and sensors. In the next few weeks they will be looking at hardware and software integration and will begin coding.

For our second meeting for UBC Voyage our website is up and running! Visit ubcvoyage.com to learn more. Our facebook page is now active, and check out our second instagram post (@ubcvoyage) for an update on our team’s progress.
Hull design was able to accomplish a great deal in the period of 2 hours. They carried a round of C sketch to ensure all designs were considered and eventually choose 2 final models. These 2 designs will be modelled on Solidworks. One design has 2 rutters side by side and the other option has one rutter in front of the other.
The Power team split up into 3 sub teams in order to research 1. how to fit solar panels on the hull, 2. how to optimize power storage, and 3. how to optimize the power distribution system.
Navigation looked into what environmental considerations must be made when designing the navigation system (eg: weather, waves, algae, etc). They finished the session by choosing a programming language for the navigation system.
The control team looked into the drag forces against the vessel and started to build a parameterizable physics model for the propeller shaft.
