We are seeking an experience engineer to design and develop an underwater (IP68 rating) enclosure with a solid and sturdy mount. The waterproof enclosure will house the following devices inside it.
1. Ultrasonic Echosounder (with transducer and its control PCB board)
2. RaspberryPI 3 or higher
3. Lithium Ion battery pack.
4. Servo motor to rotate or pan the echosounder (0 to 180degrees).
The project involves mechanical design, ultrasonic technology integration, and underwater operational considerations. The objective of this project is to develop a underwater mechanical scanning sonar system capable of retrieving the full echo response output from the single beam echo sounder device. This device is intended to use in shallow waters such as ponds and lakes of max depth of 20 feet. The range covering is targeted at 50meters.
The system will use a custom made Single beam sonar device (Transducer + integrated processing electronics to produce full echo profile output) with 500KHz frequency and narrow beamwidth.
The echosounder is mounted on a base using a with a servo motor and will rotate from 0° to 180°, obtained full echo response at each step. These measurements will be stored on an onboard memory of the controlling unit like Raspberry Pi. The sonar device will be in the water for not more than 10 scans (or full 180 degree rotations). It will be taken out from the water after taking 10 scans.
The whole system should be secured with an IP68 rating waterproof enclosure. This power source for this entire prototype (Sonar device, servo motor, raspberyPi etc..) should be Lithium battery pack.
The main parts of this prototype are:
1. Custom made Single beam echo sounder.
2. Servo motor and driver.
3. Raspberry PI for controlling the servo motor and the echoshounder device. Storing the echo output on the onboard memory.
4. Waterproof enclosure.(poly carbonate or aluminium prefered).
5. Battery functionality upto 8hours.
6. Any other required accessories/hardware parts.
Ideal candidates should have experience in mechanical engineering, ultrasonic systems, and underwater device development.
Attached is the sample design picture which illustrates the idea.
