CLAIM-EVIDENCE-REASONING

How we changed our product into what is now

CLAIM

  • A recreational drone can expand its initial functionality from aerial photography, aerial videography or simple recreational flight to include supply delivery to an inaccessible site of someone in distress through the use of an independent, custom designed detachable module.

PROGRAMMING THE ARDUINO

  • Our original module design was to simply plug the Servoless Payload Release (SPL) into the arduino using its stock cable and a stock port on the arduino.

  • After some research, we discovered that the arduino didn't have a compatible port with the SPL, so we tried splitting the SPL’s stock cable and attaching the ends to specific ports on the arduino individually.

  • We tried sending code to get the SPL to actuate, but it didn't work. We looked online, and others had similar issues in the past which they bypassed by opening up the SPL and giving power to the motor directly.

  • We tried sending power to the motor with just a battery and alligator clips, and it successfully actuated.

  • Next we built a circuit and created code to get the SPL to actuate with the push of a button on the breadboard, and were successful.

  • Next we created a circuit with a bluetooth module based off the button circuit, and we merged some bluetooth module code with the button code.

  • We tried different variations of this hybrid circuit, but It never ended up working. We then found a different style of bluetooth circuit online and modified it and our code to get it to suit our needs.

  • Finally, after ironing out a few bugs, we were successful! We were able to have a device with a bluetooth terminal connect to the module and actuate the SPL remotely, meaning someone connected can remotely drop a payload while a drone with the module is in flight.

DRONE MODIFICATION

  • Experiments were conducted to test how weight affects drone flight. This is important for our project because in order for our product to serve its purpose, then standard drones must be able to function properly with added weight.

  • The data presented in the charts shows how weight affects the speed of flight of  a drone. It shows that there is a very small increase in speed when the extra weight is included, and the functionality of the drone does not change with the added weight.

  • Based on our data, not only do the drones still function, but they still act efficiently even with the added weight. This collected data is vital for the product because it proves the functionality of the product. Now that it is proven that weight does not affect the functionality of a drone, it can be assured that our product will be able to attach to standard drones and the drone will still be operable. Testing the speed of flight is one of the most important components of the product because speed and efficiency of the drones is vital in the functionality of our project.
