Hexacopter Drone
A hexacopter drone that can transport payloads of up to 20 kilograms.
Drone Pickup/Landing Platform
A retractable landing platform is installed in each SeaPod. This serves as a pickup/drop point for the drone to deliver or collect payloads from the SeaPod. The platform has
Docking Station
Manta has a docking station that is designed to accomplish the following:
Upon docking, Manta batteries need to start charging from the charging points in the docking station. The charging points on the docking station and on Manta-1 need to be waterproof.Upon docking, the outer storage cover is unlocked and the storage container from within is pushed up using hydraulic mechanism. The storage container has a door can be opened by a user, using a 4 digit code that is generated in the application.

Optional: The platform also has a unique code (April tag) printed on it to help the drone identify the precise delivery spot. This code is unique to each SeaPod. Use Python and OpenCV with April tag to identify the precise SeaPod for pickup or delivery of packages.
Storage Container Clasps
A set of 4 container clasps are installed at the base of the storagedrone. These are mechanical clasps to grip the container, hold the container placedduring the flight and release the container after the drone has landed. The clasps are automatically programmed in the Manta-1software storageapplication space.to release the container on landing and grasp the container after a user command is received.
Storage Container
The storage container is modularused andto hasstore separate compartments. One of the compartment is an ice-box and refrigeratoritems that canare keepmeant groceriesfor andpick medicinesup atdelivery. the required temperature. Alternatively, an ice-box and a casserole can be considered.
The storage container is removablewater fromproof and can automatically picked up or dislodged by the storage space and replaced by another storage container.drone.
Cameras
8 highHi resolution cameras are placed around the body ofthe Manta-1.drone.
2 cameras in the front, under the headlights4 cameras on the wings - 2 and 2 on the farthest tip of each wing.2 cameras in the back next to the propellers2 cameras in the rear next to the propellers

Output formats | JPG, PNG, |
Date and Time stamp |
The cameras must have the option to display date and time. All 3 cameras must be set to the exact date and time in the following formats: Time - HH:MM:SS Date - MM/DD/YYYY
Optional - The date and time can be set to or Coordinated Universal Time (UTC) or Greenwich Mean Time (GMT) standard time and converted to local time in the software application or vice versa. |
Lights
A set of high powered lighting system to illuminate the sea for better visibility and picture quality. The recommended specifications for the lights are:
Feature | Value or Description |
Size | Each ring of 8 lights must not be more than 2 inches in height |
Type | LED |
Brightness | Between 1500 lumens and 2000 lumens |
Lighting distance | At least 5 meters (?) underwater |
SONAR
Proximity Sensors
A proximity sensor detects presence of other objects and/or marine creatures within a given range. Proximity sensors are installed i in the front, on the wings and on the tail of Manta-1. These sensors safeguard Manta-1 against crashing into ships, coral reefs, or rocks and boulders under the surface of the water. This has a range of 30.48 centimeters (1 foot) - in all directions. Signals are transmitted through cables and wires through the shaft to the antenna and then on to the console on the boat. These proximity sensors complement the SONAR units.
Salinity Sensor
A salinity sensor measures the salinity of sea water and other solutions. The data is transmitted through cables and over the transmitter to the console on the ship. The salinity sensor must be capable of measuring the entire range of 24-52,000 ppm (parts per million) of sea water.
pH Sensor
A pH sensor measure the pH value of sea water (salinity). The data is transmitted through cables over the transmitter to the console on the ship.
Thermometer (temperature sensor)
The temperature of water changes as we go deeper into the ocean. The thermometer records water temperature at different depths. The data is transmitted through cables and over the antenna/transmitter to the console on the ship.
Antenna/Transmitter
An antenna transmitter is installed on Manta-1 that receives data from the following:
High resolution pictures from the camerasDepth information from the SONAR/depth loggerOcean bed surface data from the proximity sensorSalinity data from the salinity sensorpH values from the pH sensorTemperature
The transmitter transmits this data to the console on the ship for analysis and storage. This data is then parsed and information is uploaded to Manta software application.
