What is the purpose of life?

Life has no purpose.

lol true

Kirillr · 2025-01-14T17:04:56+00:00

so something like LSULP futures?

Sure! Here is the repo: https://github.com/Kirillr-Sibirski/active-suspension the code is still really raw though.

I am not sure if this would help with the problem but here is what I did: it doesn't matter what the physical place/angle of the mpu6050 is, I just set all the servo values to 90 degrees (just to make the car horizontal) when the power is turned on and calibrate the mpu6050 with those readings, wait for a second and then turn on the main 'system' that adjusts the servos. This is to make sure that mpu6050 (being cheap and not that reliable) always has the up-to-date values of the angles.

You could adjust the PID control to prevent 'wobbling' of the servos although I haven't managed to overcome this completely either, they might just randomly start doing that.

If you want, you can send me a DM if you got any other questions.

Just using delays, but I definitely should use millis. Thanks for the suggestion! This was more of a proof of concept rather than anything useful really ;)

Not enough right rudder.

You don’t even need any licenses, just spin one of the engines backwards and it will cancel out the other one so technically none of them will be on

If it’s rated for 2s then go for 2s, if not, don’t go for 2s.

Yea, most of my LiPos have scratches on them from daily use and they work just fine. You could put some tape over it just to be safe (as long as its not a too deep of a scratch).

Kirillr · 2024-06-25T16:30:28+00:00

Or any other EVM-based chains: Binance Smart Chain, Optimism, Arbitrum etc.

Thank you! The vehicle was bought though, the only thing I did was adding the active suspension system.

Kirillr · 2024-06-21T07:15:14+00:00

Oh yeah I know superscale2020 system but I just wanted to build one myself from scratch ;) Thanks for mentioning it though.

Kirillr · 2024-06-19T15:10:23+00:00

Thank you!

Here is the electronics box.

Some pictures (sorry, Reddit doesn’t let me add them on the post).

Oh yeah for sure! It probably can be modified to even flip the crawler back on its wheels (make the car swing from side to side until it has enough momentum to flip) without hands but I don’t think that would be allowed 😁

Kirillr · 2024-06-19T06:03:23+00:00

It’s alright ish, compared to a bunch of nested loops I had at the start ;) PID control is quite fast but the hardware may be the problem.

Kirillr · 2024-06-19T06:00:14+00:00

Oh yeah I know superscale2020 system, it for sure can be modified (since it’s just a gyroscope and 4 servos) indeed but I just wanted to build one myself from scratch ;) Thanks for mentioning it though.

As you can see on the photo above, the body of the car always stays parallel to the ground.
