Throughout this second semester the RoboSub team has taken many steps toward being ready for our competition in August. We have successfully gotten our sub into the water moving around for the first time in team history. However, we still have a lot of work to do as we used a raspberry pi in our first test which is not able to handle the complex autonomous navigation needed in the competition. We are still working on integrating the Nvidia Jetson into the submarine to handle more complicated navigation and controls. We are going to continue to work on the submarine throughout the summer to ensure we are able to compete.

Over the last semester our mechanical team has completed extensive water testing to ensure our electronics are adequately protected. They have also worked on some of the auxiliary elements of the competition such as a grabber claw.

Meanwhile our electrical team has finished a full power board for the robot that we have been utilizing for pool testing. Additionally, they have finished a new power board that we will be integrating into the robot soon.
The mechanical and electrical teams have also been working to integrate with one another handling challenges with space in the sub as well as connecting all components together.
On the autonomy team we have taken big steps toward getting things working. We have based our simulation on the open source Orca4 github software. We have also been interfacing with an orange cube to establish communication with motors and the Jetson. Overall we are making great progress at controlling the sub. We have also had members working on a website for our team.
