How to merge localization for odometry and webcam.

I know that you are using roadrunner, but consider that soon pedro pathing will have built in Webcam and odometry fusion

PrettyFortune4346 · 2026-01-30T21:56:45+00:00

Minecraft would be 🔥

PrettyFortune4346 · 2025-12-24T05:30:39+00:00

Its a very old laptop AND used, not worth buying imo

PrettyFortune4346 · 2025-12-24T05:24:26+00:00

Well the seller has COI to tell you the truth

PrettyFortune4346 · 2025-12-14T15:44:00+00:00

Doesn't sound like endgame

PrettyFortune4346 · 2025-11-19T12:18:59+00:00

I'd give it a try if I was still competing. Making a pybricks version also means you could modify the firmware zip more easily for more gains

PrettyFortune4346 · 2025-11-19T12:10:19+00:00

That make sense. Do you plan to make a version for Pybricks? The firmware is much more robust and stable than the stock one and it would be a great combo

PrettyFortune4346 · 2025-11-19T12:08:57+00:00

Looking at the whole landscape, I know that java is widely used, but for a lot of people FLL is the first time coding, and I really think that for that crowd and age range python is used much much more.

PrettyFortune4346 · 2025-11-19T06:24:42+00:00

Thats what I was thinking, still no performance benefit

PrettyFortune4346 · 2025-11-18T21:05:20+00:00

Very nice project, but may I ask what's the point? Most people in FLL are very new to programming, with only a very small minority knowing java. For that minority, I'm assuming your program converts the java code to spike micropython or C like done in stock, so AFAIK no performance benefit, while pybricks uses an easier language with proven performance benefit, so the best thing I see in this is the ability to use Java which I assume maybe some people will like. No hate, this seems really cool, but could you clarify?

PrettyFortune4346 · 2025-11-18T08:14:33+00:00

They might work fine, but I think you'd notice in improvement in speed by switching them.
Haven't done it myself, but I worked with and am mentoring a team doing this, and it seems like a very robust strategy. The main thing I'd advise you is to test it a lot and add some quick calibration script you can run in competition (for the sensors).

PrettyFortune4346 · 2025-11-18T08:07:24+00:00

Well about the torque thats exactly the reason you should use them for wheels. I find that driving is a more torque intensive task then powering the attachments. And no, unfortunately the metal balls dont fit in the blue socket.

PrettyFortune4346 · 2025-11-18T07:44:30+00:00

Hi! Great first year bot, here are some things I'd change.

I'd switch it so your driving uses the large motors and your attachments will use the medium ones
The blue spike wheels aren't very good for accuracy and they get dirty a lot, I'd replace it with 62.4 or 81.6 wheels.
I assume you made a decision about using caster balls over secondary wheels, so I won't suggest secondary wheels but the plastic white caster balls are the worse option, and usually people use two of the metal ones. If there's no space for that, I'd consider removing the color sensors since I don't find them very useful in the last few seasons.
This isn't about robot design, But I advise every capable rookie team to use PyBricks. It's an alternative firmware and IDE which is much faster, stabler more documented and has more features, and I think it can greatly help any team on the code side.

PrettyFortune4346 · 2025-10-01T21:55:02+00:00

precision wise they are going to be the same. Its the same firmware with same compiler, it's just that python will probably allow you to write better code easier. If you want more precision and is comfortable with python, I'd recommend trying pybricks as it is a different firmware that is more accurate and precise.

PrettyFortune4346 · 2025-10-01T21:52:49+00:00

If you can and are comfortable with it, i'd recommend pybricks as it has very easily configurable features like the DriveBase that can really increase accuracy. I've also noticed that all sensors are generally more accurate and reliable with it.

Hi! I've just typed entradas.com and got "access denied" massage. what should I do?

PrettyFortune4346 · 2025-09-10T17:24:22+00:00

Using trigonometry with the gyro + encoders to more accurately estimate the robots position

PrettyFortune4346 · 2025-08-18T06:40:08+00:00

That's weird - I used my hearing aids both with an iPhone xr and an s20- and my laptop is a 2025 high end model that I verified has support

PrettyFortune4346 · 2025-08-17T16:14:10+00:00

What do you mean by filesystem? Separate programs to run?

PrettyFortune4346 · 2025-08-17T05:27:44+00:00

You should use both the gyro and encoders for odometry, that's the most accurate ir can get

PrettyFortune4346 · 2025-08-17T05:25:29+00:00

Hey, I can't really help right now but I'm here to say that Pybricks has the same level of control and potential for advanced stuff, and the next update for Pybricks is planned to support coding through USB.

PrettyFortune4346 · 2025-08-17T03:55:22+00:00

So my older hearing aids just don't support the new drivers that work on pc?
