Here are the 3 workshops that will be conducted for the electrical subteam
Our new hull is fabricated by Computer Numerical Control (CNC) machining of aluminium. This design eschews the conventional circular hulls of our previous vehicles, instead opting for a more boxy rectangular shape. The rectangular hull helps to increase the packing efficiency of the rectangular PCBs in the main hull, consolidating the majority of the components into a singular hull.
The hull separates the power handling components from the signal and data processing electronics into 2 compartments. The aluminium partition wall provides structural support to the hull and aids in isolating electrical noise. With our slot mounting mechanism of electrical components, we are also able to get much easier access to each component in the hull for simpler troubleshooting.
For our battery hulls, we were fortunate to be sponsored by SLM Solutions. Using their additive manufacturing method, we were able to utilise internal lattices and isogrid patterns for the walls and base of the battery hull. These internal structures increased the rigidity to weight ratio of the hull, resulting in a significant reduction in both the weight and volume of our battery hulls.
Diverging from our previous pneumatic actuators, we have transitioned to a fully electrical actuation system. The torpedo system works with latched internal springs, and are released with electric servos. By eliminating the bulky and heavy pneumatic system, we were able to reduce the footprint and complexity of our actuation system.
