RoboBoat - Mechanical
Overview
We elected to use a catamaran over single-hull designs due to higher stability in water combined with lower drag. We based our hull design off Institut Teknologi Sepuluh Nopember’s Nala Proteus while employing our own manufacturing techniques with fiberglass, a durable material used by several teams.
Barco Polo Hull
We leveraged our existing composite fiber glass hulls we created in 2024. The core of the hull comprises of extruded polystyrene. This core served as the mold to lay up a sheet of fiberglass weave and two layers of fiber glass mat. Everything was sealed with UV cure resin and finished with top coat.
Water Pump
Networking with other RoboBoat teams, we decided on procuring an off the shelf water pump from Amazon. Coupled with a nozzle to accelerate the water we are able to perform the Water Delivery task 2 feet away from the Orange Vessels. The pump extracts water from the lake at the competition venue.
Racquetball Launcher
Leveraging past experience from land vehicle competitions the team decided to implement a puncher mechanism. A DC motor powers the driving gear, which contains only 3 teeth. The gear compresses the spring by drawing back the rack on the punching rod, as the drive gear continues the rotation, the rack slips and the punching rod launches the racquet ball towards the Black Vessels.
Thruster Guards
From our previous experiences in RoboSub and RobotX, our team has realized the importance of strong thruster mounts and shrouds. These new thruster guard enables positioning of thrusters and provides a failure point during harsh impact which will fail before the injection molded case of the T200 thrusters fail.
