Automatic Airboat #ME KKU 02
NAME’s SHIP
“ The Wingless angel Nemo ”
MEMBER
Mr. Chaiwat Sawasnatee
Mr. Chayakorn Wetsawan
Mr. Wachirawit Thaochalee
Departent of Mechanical Engineering, Khon Kaen University
Objective
Learn how to build an autonomous ship.
Apply our knowledge to do this project.
Study how do sensors work.
Learn more about C programming language.
Practic teamwork.
Design Concept
Our inspiration is a space rockets because front of ship is peaked and
the shape is similar rocket so it is elastic and moving fast. Under the boat
have some fins to control the stable vessel.
Power sources : DC battery.
Propulsion method : Have to be fast and easy to turn.
Sensor: Able to check the distance and know the direction.
Microcontroller: Easy to use and cheap
Design
Power sources
We use lipo battery 3 cell 2200 mAh
12v
Propulsion method
We stick the motor to srevo so it esy to run and trun
Sensor
Ultrasonic sensor
We ultrasonic sensor to check distance of obstacles
Goal
Obstacles
Surface of goal is quite smooth in vertical but obstacles not
so we use 2 ultrasonic in vertical to check goal and obstacle
compass sonsor
We use compass sonsor to check direction.
Microcontroller
We use arduino board because it easy to learn,use and cheap.
Construction
1. Cut kick board into shapes.
2. Cut plastic for holders.
3. Install propeller with shaft of motor.
4. Install motor with plastic holders by screws.
5. Install plastic holders with stern boat.
6. Install battery at mid boat for stable.
7. Install plastic walls at front boat to prevent water into the boat.
8. Install fins at under the boat.
9. Experiment the mobile of the boat
10. Connect all sensors between boat and microcontroller board..
11. Write code of program and burn to microcontroller.
