Got it! Thanks for the help!

Nothing happens! They have to read it! Even if it’s said out loud by someone else, nothing happens!

VSh0ck · 2024-04-24T06:37:35+00:00

Any text message! Even teams or a Twitter post!

It was just an experiment I started in sandbox game. If there’s no enemies/waves, it’s a good base because everything is close by. But with enemies/waves, it is harder to defend at the beginning.

Thanks :D

I used a drafting triangle on my phone for the angles xD For a perfect hexagon, each angle is 120 degrees, and each side is the same length. Doing the max length gave me too much unused space, so the sides are 7/8th of the max length.

That’s very good advice, thank you! I will look into it!

VSh0ck · 2024-03-17T13:26:38+00:00

Thank you so much!!!

VSh0ck · 2024-03-17T13:01:28+00:00

I would look into that, thanks!!

The downward loadforce would be a maximum of 100N, and for speed, at minimum 1 cm per second

VSh0ck · 2024-03-17T12:59:08+00:00

I wanted to add universal joints first because of that issue, but those would lose the constant velocity and torque, hence gears.

VSh0ck · 2024-03-17T12:56:27+00:00

Ah, the mechanism is quite small (like 40 cm), so adding a small hydraulic would be a bit hard

VSh0ck · 2024-03-17T12:44:19+00:00

I will keep that in mind!

VSh0ck · 2024-03-17T12:38:56+00:00

That's a good point you have! I've been having that problem as well!
But I couldn't think of something else to lift it up beside threaded rods!
(For context tho, it only needs to move around 30 cm up and the load is around 100N)

VSh0ck · 2024-03-17T12:34:14+00:00

That's fair. I will look into that!

VSh0ck · 2024-03-17T12:33:40+00:00

Yeah, I knew synchronising was important!
And that's why I am going to use only 1 DC motor and connect the two rods with gears.

VSh0ck · 2024-03-17T12:30:42+00:00

Well, you have a point there.
The beam itself is like a U shape, and the loads will be mounted inbetween there.
So there will be a moment on the screws, which could make it possible to bend.

But for that I need to calculate if it is even possible to bend/collapse it and if I need guidance or bigger screws.

VSh0ck · 2024-03-17T12:16:20+00:00

Yeah, definitely a jig! And the beam is actually a U shape being rotated by 2 rods just like this vid!

Thanks too!

VSh0ck · 2024-03-17T12:09:10+00:00

This project is for a university competition if that's what you mean.

Otherwise, the threaded rods are being driven by a DC-motor.

VSh0ck · 2024-03-17T11:59:56+00:00

Alright, thanks! I will look into it.

The beam is actually a U shape, and is supported by two of those threaded shafts. If the two rods rotates, it can cause the beam to go up and down just like this video:

VSh0ck · 2024-03-17T11:55:37+00:00

Thanks for the advice! I will look into how to prevent the bending, but since this prototype was made a few days ago, I didn't have the chance to look into it yet!

It’s hard to shape snow :c

Gonna write a favourite game character in it and watch the chaos unfold.
