Goal:
Create a dropping mechanism for the your drone. Mechanism must hold a water bottle securly. It must contain a servo. This servo must be controlled by the transmitter or through atonomous programming. The mechanism must be able to release the bottle upon request.
How the Mechanism Works :
The turntable holds the top part of the bottle, or the neck. The arm is connected to a 360° servo and turns to push the bottle depending on its position.
Our main goal was not to make the drone too heavy, but still carry three bottles. Also wanted to save time for our future missions.
Refer to gif to know where parts are placed and how they interact. P.S. that is the wrong rotator arm. When the gif was made, that was the current stage of the arm.
This was the first design idea by Nathaniel May. The idea was to hold all 3 bottles at one time and would be pushed by the rotator arm in the center. This design was the starting point for all the future designs. It ended up being discarded because of the walls and because it was so big.
This design was very complicated. The idea was to have holders fo the water and when one was moved, it would get to a point where it would catch on to the next one and then rotate that one as well. This was discarded because it required me to do math which I didn't want to do.
This was the first design that used the special Bottle Neck design (pun intended) where it starts out small and then opens up, allowing the bottles to fall down. The bottles would be loaded in by sliding the bottle neck in the slots.
This design got rid of the walls and added in an arm. It ended up not being used because there were too many slots. When the bottles were put in they all bumped into each other and caused issues.
This was very close to the final design, but it had a couple of issues: one, the attachment slots were measured wrong and the Bottle Neck Slots were too loose.
This was the final version of the base. It has a combination of everything that worked from the past ones. This design holds the water bottles by the lip under the top and is pushed by the arm. The attachment cut outs on the four corners fit very well and were very started.
This design sucked a lot. It was overly complicated and huge.
This design also sucked a whole bunch. It was also overly complicated and weird.
These two designs were my attempt to make the arms better. This would have connected to the Bottle Neck baseplate design, but it ended up never being used.
After my lame designs, Dileinka took over and created these two designs. There were a lot of small variations, but the biggest changes were the opening and the servo hole. The servo hole was given notches so the arm would grab the servo. This design was used for a while, but then changed because it wasn't pushing the waters.
These two designs were my attempt to make the arm push the waters. Both failed. The idea was to spin with the base, pushing the waters straight, instead of pushing the waters into the walls
This was the final design. It works very well because of the curved hook design. This is placed in the center of the base and the top attaches to the servo.
Original baseplate
Due to our drone having a cracked base, Dileinka came up with this design to reinforce the base. It had a ton of measurement revisions but this was the basic idea: it used clips on the top to attach to the base of the brone.
These two had very similar ideas. The only difference is how long the top is, the measurements and the fillets. This was a hybrid of Dileinka's ideas and mine. It replaces the full base, and instead there are 3 of the long one on 3 of the corners. The chubby one ended up not being used.
The fully printed part
This design is different from the rest because it is the camera mount. This attaches to the drone using the top notch (which is a very top notch top notch, if I do say so myself) and has a flat platform with a hole in it for the camera to mount to.
This is the arm. Say hi. This is meant to attach to the base and the hooks above. This design was trashed because the slat was unnecessary.
This was too tall and skinny. This is an arm, not an Enderman, so it was discarded.
This design went through too many measurement changes, but this is the general idea. The final design was short in height, long on the top and stout on the bottom clip.
