The robotics team of Institut Teknologi Sepuluh Nopember (ITS), Banyubramanta, again creates innovations in Remotely Operated Vehicle (ROV) robots. This underwater diving robot designed by Banyubramanta achieved six award categories at once on the national Underwater Robot Challenge – Wonderfull Indonesia Robot Challenge (WIRC) 2021 , some time ago.
General Manager of the ITS Banyubramanta Team for the 2021-2022 period, Afrizal Pradana Firmansyah, explained that there were two kinds of robots, namely the Sea Wasp robot and the Glaucus Atlanticus robot. A different sub-team holds each robot. The Sea Wasp robot has a more extensive dimension specification than the Glaucus Atlanticus robot.
The 3D design software used is also different. The Sea Wasp robot uses Solid Works, while Glaucus Atlanticus uses Autodesk Inventor. “In essence, the two sub-teams carry the concept of an underwater robot with different frame designs, PCB circuits, and robot dimensions,” he explained.
Afrizal said that overall the mini ROV robots designed have the same way of working. The second robot can be controlled using a remote wireless system with a motor and propeller ( propeller ).
Then the microcontroller will instruct the motor driver to drive the motor. So that the robot can move as desired by the user, such as forward, backward, turn right, turn left, and even turn. “In addition, the team can run the robot’s capabilities underwater to a depth of 30-50 centimeters,” said the student from Pasuruan.
Due to the current mobility demands, he continued, both robots were designed with a waterproof design to protect their electronic components. In this case, the team used a plastic food container as the body of the robot. Furthermore, there is a 3D printed part for the body frame, which functions as a place for the robot’s motor, which is located on the outside of the body.
“The front part of the robot is also equipped with a DC pump motor that is useful for missions at the WIRC event, such as taking and moving marbles as underwater objects,” said the Department of Electrical Engineering student.
