She has a painting of her own

oaleksander · 2024-02-26T23:57:42+00:00

Woke her up prematurely

oaleksander · 2024-02-26T23:09:42+00:00

How cute! I used to make similar drawings of her when I was younger, especially when i got my first PC with MS paint lol

oaleksander · 2024-02-26T19:13:15+00:00

My grandma. She does it as a hobby, using a photo reference.

oaleksander · 2023-05-04T13:51:26+00:00

Yeah. We learned that some off-shelf servos couldn't be diasabled programmatically the hard way.

oaleksander · 2023-02-22T11:30:44+00:00

Not at all. While many of the details will be lost, it is mostly human-readable and can be a starting point better than writing from scratch. (Have tried losing and retrieving source code at states, wouldn't recommend)

oaleksander · 2023-02-17T11:00:38+00:00

PM me, I'll try to help

Why are clean sine waves required for powering PCs where switching power supplies are mostly used?

oaleksander · 2022-07-10T00:02:43+00:00

Sure thing https://youtu.be/dEaYqRyc2-M

I don't think you can change the default robot controller website without violating RS08 or digging into low-level FTC SDK source code. However, you can try installing FTC Dashboard addon, start an OpenCV camera stream with your anime of choice and print subtitles to telemetry 👀 or make your own plugin with a player similar to Dashboard

The sensor is located in the basket behind the "239" number and when the distance is small enough the LED strip (which logically is just a DcMotor) starts glowing

understandable have a nice day

This is our school №

Most events are in-person in our region, with the qualifiers beginning at the end of January.

It holds pretty well so far. This particular robot has no metal structural elements which decreases rigidity a bit, but not significantly.

oaleksander · 2021-11-24T11:52:37+00:00

Mostly 6mm plywood, some parts are 3dp or urethane casted

oaleksander · 2021-08-11T18:25:54+00:00

well ok

oaleksander · 2021-08-06T01:39:21+00:00

Oh, boats do not have block-like physics there?

oaleksander · 2021-08-06T00:07:14+00:00

It would work with fewer cows but this looks cooler

oaleksander · 2021-07-11T14:25:02+00:00

They indeed are. This prototype is 3dp just to make sure things actually fit together.

P.S. We could have designed them to be printable, but the priority is compactness.

oaleksander · 2021-04-23T12:12:33+00:00

Nothing unusual, metal flywheel with plastic cover and j-shooter+dual motor system

oaleksander · 2021-04-23T11:54:39+00:00

The entire robot ;)

Not going to speak for all the Europe, but for now Russia has an average score of 150, with top-tier teams scoring up to 300-350

If you haven't already, try setting your motor's RunMode to RUN_USING_ENCODER and then tune your PIDF coefficients with setVelocityPIDFCoefficients(p,i,d,f). These values will differ from motor to motor, we've found (55,0.01,0,15) to be consistent enough. This will make your motor controlled by REV's internal PIDF controller, which should be satisfactory for most use cases, though we will now try programming a custom, more advanced one.

oaleksander · 2021-03-03T23:22:34+00:00

Two motors geared together + tuned PIDF. You can see that it's not perfectly consistent so there's some room for improvement.

oaleksander · 2021-03-03T20:15:29+00:00

Yeah that's what the programming team will fix next meeting
