Drone Building
Drone Building
This was us soldering our wires to our circuit board since when we received it, the board was in complete disarray.
After doing soldering for a few days; we finally moved onto attaching all of the hardware and motors that weren't previously attached.
This was around the time our group was wrapping up with landing gear (as seen here) and with the building process in general. We started to do motor checks and sound checks. This was when we realized that our motors weren't working nor was our circuit board.
This was us testing our motors and realizing they didn't work and neither did our circuit board and it wasn't giving any signals even when we tested it with a multimeter. We decided to restart.
This was reattaching the new motors and hardware, the 4th motor didn't work so we had to replace that too (it was the one that was originally crimped so maybe that's why).
Landing Gear
Landing Gear
Objective:
The student will design new landing gear for the drone. The design cannot be what the drone had on it the previous year. Any material or software can be used to create the landing gear. Once the gear is designed and made. It must be installed on the drone. Keep in mind that the gear must be tall enough for the dropping mechanism clear the ground while the drone is landed.
Due to the original solidworks file disappearing I have this showing the landing gear in the prusaslicer.
This is showing the infill and individual layers of the landing gear.
A picture of the landing gear on the drone we used two zip ties both facing opposite directions to keep it snug in place. It has minimal movement and fits tightly around the drone.
The front landing gear colored white to be visibility.
The back landing gear colored green for noticeability.
Dropping Mechanism
Dropping Mechanism
Objective:
Create a dropping mechanism for the your drone. Mechanism must hold a water bottle securely. It must contain a servo. This servo must be controlled by the transmitter or through autonomous programming. The mechanism must be able to release the bottle upon request.
This is the lever that grabs the door and pulls it.
A component that holds the lever
The box that holds all the components and the trapdoor
The dropping mechanism using a servo to push a trap door open and release the package.
Arm component that moves the servo
The top of the box that connects to the drone
Test Flights
Test Flights
IMG_8990.MOVOn our first attempt, one of the ESCs for the motors failed. After replacing it, the drone flew well enough to be piloted to the football field and back.
An example of loiter mode, which stabilizes the drone in place.

Flight #1
Flight #1
Before we were using autonomous flights but this was one of our first flights using mission planner that worked successfully.
Flight #2
Flight #2
One of our flights coming back from the football field. The drone was kind of wobbly due to the harsh winds.
Flight #3
Flight #3
with black pearl
(Our first few times ususing the black pearl were great but after using it for awhile it would constantly over heat and then cut out.)
Flight #4
Flight #4
One of our flights with the dropping mechanism being used. The dropping mechanism turned out sucessful.
