What a year it has been for the Hornet team!

With Hornet 2.0 improving after every pool test, it seems that the many pieces of Hornet 2.0 are coming together but we still have some way to go. This upcoming week, Hornet 2.0 will begin testing computer vision. Computer vision is a method of detection that allows Hornet 2.0 that gives the vehicle ‘eyes’ to navigate through each of tasks whether it be passing through colored gates or acquiring a ball from colored buckets.  Over the last few months, the software team has been busily learning about the complexities of computer vision and we look forward to putting our algorithms to the test to make Hornet 2.0 the best vehicle it can be.

In Hornet 2.0, we are using 2 ODroids for our SBCs. These, coupled with our servo actuator, required us to provide a 5V power rail that allows a maximum current of around 10A. Since linear regulators would have resulted in low power efficiency at such high currents, we decided on the use of a switching regulator. We initially made our own regulator, which was rated up to 5A, but had some troubles maintaining a constant output voltage at higher loads of 3A. We then came across this 5V15A switching regulator from Pololu (https://www.pololu.com/product/2881/), which suited our needs perfectly. The form factor of Pololu’s regulator was small, yet able to provide a large enough current, and allowed us to save much valuable space in our electrical rack. Many thanks to Pololu (https://www.pololu.com/) for supporting us by letting us purchase the 5V15A regulator at a discounted price!
