Computer vision acts as the eyes of a robot,
126+
allowing it to perceive its surroundings and coordinate
127+
the data through integrated software and hardware to its other
128+
components. We have set up an NVIDIA Jetson as the primary
129+
computing platform for our project, this will allow us to
130+
leverage its GPU acceleration to run our own version of the
131+
YOLOV5 model for real-time object detection. We have been
132+
working on building a lot of OpenCV tools that will help us with
133+
preprocessing tasks such as image filtering, noise reduction,
134+
and edge detection. This will improve the quality of our input
135+
data for the model. Our plan is to tweak and further develop a
136+
custom trained YOLOV5 model by gathering our own data from real
137+
world data collection and testing within the real world. To
138+
gather this data we will be using stereo vision footage from our
139+
ZED 2i camera and preprocessing the data with OpenCV, then using
140+
the data to fine tune the model to account for water distortion,
141+
object occlusions, and lighting inconsistencies. By combining
142+
the Jetsons hardware acceleration, OpenCV's tools, and YOLOV5
143+
object detection capabilities, we will deploy a highly efficient
144+
and robust visual processing system that will be capable of
145+
real-time inference within dynamic underwater scenarios.

Due to the surge in AI popularity, our progress on computer
148+
vision has faced significant delays as we struggled to acquire a
149+
Jetson Orin Nano, our preferred board for vision processing. In
150+
the meantime, we borrowed a Jetson Nano, but this introduced
151+
another challenge—the board officially supports only Ubuntu
152+
18.04, while our ROS Humble software stack requires Ubuntu
153+
22.04. One of our members has been working on upgrading the
154+
system and has successfully installed Ubuntu 20.04, bringing us
155+
a step closer to compatibility.

With basic navigation implemented, our goals are set towards
166+
completing the computer vision and path planning systems.
167+
Computer Vision is absolutely necessary for localization, and is
168+
by far the most crucial component we are missing. The addition
169+
of path planning algorithms will allow for the creation of more
170+
complex paths that can minimize distance while avoiding
171+
obstacles in unmapped terrain.

The Cabrillo Robotics Club recently participated in MESA Day
336+
at the University of California, Santa Cruz, an event that
337+
brought together over 250 middle and high school students
338+
from Santa Cruz and neighboring. Throughout the day,
339+
students engaged in hands-on activities and connected with
340+
industry professionals and STEM organizations, including our
341+
club. We showcased our SeaHawk II and LazerShark robots and
342+
led an interactive bristle bot activity in which students
343+
got to build and race simple bots.
