A)OVERALL FUCNTION DIAGRAM

B) Function Tree.

Here is the process from which the drone derives its functioning to fulfill whatever tasks demanded, where the left branch is dedicated to planning a route while the second to navigating through that route.

C) FUCNTION DECOMPOSITION

this was an example for A drone, Now we want for a medical ventilator

Breathing assistance devices are used to help patients with acute respiratory problems caused by pneumonia-related illnesses such as COVID-19, asthma, and dry coughing. The most often used equipment for COVID-19 treatment are an oxygen therapy device, a ventilator, and a CPAP machine.. Throughout the review, we discussed the most recently produced breathing help equipment, such as oxygen treatment devices, ventilators, and CPAP. A comparative study of the created devices is also provided, along with the required obstacles and potential future directions.

Thank you very much for the consideration for this question !

Item to be transported ----> Command from user------> Transport items from point A to point B arrival at point b and delivery of package. Provide with package. Charging the battery Collect environmental data via sensors Gain altitude using rotors. receive waypoint via calculations. detect obstacles using sensors. navigate following instructed directives. plan trajectory and time of arrival. Arrive at destination and lower output of rotors. adjust power output based on collected data release packet. receive new input and go back to function one: provide with package. Remote control Propellers launching Electricity Charge of the battery Energy transition from electrical to mechanical Motor rotation Drone flying done. (x and y and 2) coordinates of the destination. The coordinates are transmitted to the Sensors. The location is processed by the GPS and sent to the micro-computer. Shortest path to destination is available. Images and path sent out Packages Carries weight and place it under protection Parcel ready Camera Camera keep track of everything that is happening around, records it and transmit it to the micro-computer which is mathematically an edge between the drone world and the world of the computer scientists who keep track of the drone
