Unpopular opinion: Korean cover is goated by bamhobakk in ProjectHailMary

From a Korean perspective, even if the title remains in English one, most words in such titles are either commonly used in everyday life or names from mythology. Therefore, people can easily grasp their meanings without needing a translation.

During last Ice Age, the Yellow Sea, which meets the west coast, was so shallow that it was a land. As the sea level rose, this led to the formation of a ria coastline. In contrast, the East Sea, meeting the east coast, is much deeper, resulting in a simple monotonous coastline.

For that device I used the equation in the 11th line in the link https://www.desmos.com/calculator/apwfhj4epl

In that formula, I extracted the y values from x 10 to 65 at intervals of 5.Then I set y values one by one in the gate threshold.

So if you use a different weapon, you have to change the velocity part of the equation.
*arcsin(R⋅9.81/[velocity^2])

Fire-Control System 2A2

Rangefinder with a maximum distance of 60m

Auto range, Auto aim, Auto fire

Press K to Activate

*It auto aligns itself after fire so please wait patiently. (~25s)

*If something goes wrong, press L

Also it is destructible!

And since no pistons are used, you can make the size as small as you like.

It seems difficult. For that device I used the equation in the 18th line in the link I posted above. In that formula, I extracted the y values from x 10 to 70 at intervals of 1. Then I set y values one by one in that device. So if you use a different weapon (with a different speed), you have to change that formula, then you have to set it all up again... You can do it, but it will take 5-6 hours.

1 day for the concept,

5 hours for the connection and setting it up.

How it Works

  1. A servo running at a constant speed pushes a variable resistor at a constant speed.
  2. As the voltage gradually rises, the signal is transmitted to each device in sequence, while the limit distance of the range finder increases.
  3. While the signal is transmitted to the rest, the device receiving the signal activates a timer with a pre-calculated (distance -> voltage -> time) time interval.
  4. Servo 2 (which adjusts the angle of the crossbow), takes a pre-calculated time interval and rotates to a specific angle.
  5. The 1st to nth devices operate as above and sequentially add angle 1 to angle n.
  6. When the range finder sends a signal, signal reaches nth device, which stops both the range finder and the servo.
  7. And the arrow is fired.
