The E-bay (electrical bay) temperature is regulated via an open water cooling system. In an open water system, water is pumped in from the lake, passed through a heat exchanger to cool the air blowing over the electrical components. Using the environment to its advantage, the cooling system will effectively regulate the E-bay temperatures using …
The boat uses dual T200 thrusters that are mounted on the back of each ama. With two thrusters set 2 feet apart, the boat maneuvers with differential steering; capable of moving forwards, backwards, spin in place, and any combination of the three. Thrusters are controlled via Electronics Speed Controllers and Pulse Width Modulation (PWM) through …
Main Hull The general idea for the manufacturing plan of the main hull is to cut out profiles of the boat to use as guides to sand down a foam mold. After the foam is sanded to shape, a fiberglass layup is done on the mold. Once the layup is complete, the fiberglass is then …
The skeeball mechanism utilizes a single vertical rubber flywheel to launch the game piece for the shooter task. The wheel, attached to a metal axle, is powered by an F2838-350kv-Z underwater DC motor. For the indexer, a gravity-powered turntable feeding mechanism is used to store the game pieces. It is powered by a Nema …
Cad of Assembly Trimaran This year we opted to go for a trimaran design to maximize stability. Stability is crucial for our mission since the computer vision model works best when viewing a clear image from the camera. Trimarans are very stable due to the two hulls on the side (called amas). If the boat …
Safety During the competition, several safety measures have been implemented in order to ensure the safety of our team and other participants in the competition. The most important is the remote and onboard emergency kill switch. The onboard kill switch is large and easily reached by personnel. Our vehicle can be terminated by our ROS …
Intro The Computer Vision group on the Computer Science subteam is responsible for choosing and training an object detection model to detect the components of the competition course from a live video input. Our tasks consist of uploading data, labeling objects, and using our results to compare then improve our model. Annotation Roboflow was used …
Intro The Motor Control group on the Computer Science subteam is responsible for implementing our autonomous decision making capabilities and controlling the motors accordingly. In short, we use what the boat “sees” (a list of objects detected by the computer vision model and their associated distances from the boat) to dictate how the boat moves. …
The ZED 2 camera made by Stereolabs provides the Computer Science subteam with cutting-edge technology including neural depth sensing, 3D mapping and object detection, a built-in IMU, and more. When integrated with the Computer Vision group’s custom object detection model, the ZED’s depth sensing abilities will provide information on where buoys and other competition obstacles …
