Testing Log 1: Initial Assembly and Lake Testing

With the RobotX 2024 competition no more than 2 months away we decided we needed to start testing now. On September 9th 2024 we embarked on the first testing session of the new school year! In the morning, we finished assembling the boat, including mechanically mounting several sensors and the computer box, securing electrical connections inside the computer box, and distributing outbound wires from the computer box to their respective sensors/actuators. Around 1, we wheeled NaviGator outside and hitched it to the ECE truck. We successfully drove it to Lake Wauburg and backed it down the driveway to the boat ramp. We deployed it, and after working through some computer issues, got the boat to move using odometry and the path planner. We will be testing next Sunday. This week, we aim to finish code for several missions, add further reliability to our software systems, work on new electrical boards for the light tower and RF kill, and build props used for testing missions in the water.

Testing Log 4: Enemy Filtering and Wildlife Mission Testing

-

Unfortunately due to the hurricane and its impact on Florida, Lake Wauburg (our usual testing site) was without power today and therefore closed. After working together to find some other lakes to test in, we settled on a lake in Marion County named Orange Lake. After configuring the LIDAR bounds to work at the new lake, we got started with testing. The enemy filter (aka, filtering out non-useful LIDAR points in front of the boat) worked better, but we were still encountering a lot of issues with the LIDAR and the underwater weeds, which rose near the surface of the lake. We think that the changes to the LIDAR filter will work at Wauburg, where the weeds aren't as high and the light is the main deterrent in getting an accurate object map of the environment. Nonetheless, we recorded some data to analyze later, to try to further improve the filtering of the LIDAR. We also briefly tested the wildlife mission, and found some ways to improve it. Thanks to everyone who came!

Testing Log 5: Enemy Filtering Part 2 and PID Tuning

+

Testing today was good! We showed up at Wauburg right at 12, and left right at 6. Today, we fixed the enemies issue by implementing a secondary point cloud filter to filter out low intensity points. Often times, light reflecting on the surface of the water would be relatively low intensity, so this filter worked great (the red points in the filter are the light reflecting off the surface of the water at the LIDAR, which are filtered out/not collected into a box, like the rainbow points and box representing a kayak). We collected some more image data, and investigated the path planner and PID controller a little bit. The boat is oscillating back and forth quite a bit when trying to align itself with a goal sometimes, which will make some complicated movements harder. We also worked on the bounds, and tested the blind path planner (which worked more consistently). Also, daniel and i (cameron) fell in the water lol.
