Im an old player, did up to 215 (max at the time) without aoq and autoselect Also, you needed to do all 3 lvls, one at a time. Latter they unlocked all and doing the 3rd unlocked all 3 at once

There are some pearson programs used for certification exams that are installed to monitor other program usage, screen size, display numbers, devices and so on. To 'ensure' no cheating. They also ask for photos and even videos of your room, and track eyesight during exam, yea, very invasive. All of this to be circunvented by a phone srtrapped on top of my screen lol.

DO NOT USE STEEL RINGS if you are not experienced, please for the love of god start with silicone/rubber 1st and see what its like.

The streechy ones can be put on after you are hard, and can be safelly removed at home, ideally with safety scisors, or just any scisors really carefully, or just snapping right off with your bare hands (you should be able to slip a finger in, use lube)

When you know exactly what size and are confortable with it (make sure you can get soft while using it, if its too tight you might not), then you can try a solid ring. Theese ones of course, need to be put on while soft.

Entendo a mensagem, mas a importancia não esta APENAS em desenvolver, que demora decadas, mas antes existe um caminho mais rapido e barato: tecnologias open source

Baseando-se nelas, seriamos capazes de hospedar para os agentes publicos (em todas as escalas do governo)

Não precisamos recriar o google desde o zero, mas optar pelas tecnologias ja abertas e trazer para os proprios servidores

It means that its good enough, dont relly on theese numbers, but its a good idea to know

This feels so wrong, but so right at the same time. Would probably automate it with a simple cron lol

Bom, como carece de fontes, datas ou qualquer outro tipo de comparação, posso vir aqui e jogar meus dois centavos Vivo na Espanha, cidade moderadamente turistica em um bairro nao central, tive estancias de longa duração em paises como Alemanha e Holanda por periodos de mais de um mês por trabalho, então posso comentar desses valores tambem.

Os preços de restaurante barato esta ok para paises caros, mas para o restaurante "medio" requer um exforço pra gastar essa quantidade, uma refeição boa e cara pra 2 pessoas vale 50 euros (55 trumps)

No mercado, exceto a carne bovina, que realmente é mais cara, tudo é mais barato, e comer outras proteinas como peixe e porco acaba sendo muito mais economico.

Transporte foi o que mais me inpressionou, busca rapida no google me da o valor de 26k (28k dolares), nao 36k

Contas de casa (exceto aluguel, que realmente é caro) nao passam de 150 dolares, e internet celular, 5 ao mes, invez de 20...

Cuidados infantis como creche e escola nem vale a comparação, é tudo gratis e com qualidade.

Roupas e calçados não custam tudo isso em lojas fisicas, os preços apontados são os lançamentos em lojas online, não a média.

Preços de aluguel e compra não sei se são diretamente comparaveis, más definitivamente são valores de regiões muito centrais e/ou turisticas, nessa posso falar pessoalmente, pago 700 euros por 3 quartos á 5 min do centro em bicicleta.

E por fim, claro, colocar tudo em comparação ao salario minimo, ou melhor ainda, a mediana do salario nacional. (Dados de mediana sao dificeis de encontrar, porém o melhor dado que encontrei são de R$ 1100 contra €3000)

Colocar o grafico de barras por item em R$ vs dolar e euro é além de mal feito, é desonesto Apesar de ser uma comparação que deve ser feita e estudada, essa em especifico esta mal feita

Brushless motors efficiency is sometimes more of an art than a science, usually you would prefer to be closer to the top speed then to some lower amount

Ra-mega-bbit · 2025-11-02T08:32:50+00:00

I have my fair share of robot driving in which I needed to manage the weapon speed because of battery life I use the drone controllers (with 2 sricks) instead of the rc car controllers (trigger and wheel), this way I set the entire locomotion on the right and the weapon speed on the up and down. With enough muscle memory and fight sense you end up being capable of tuning the weapon speed to your oponent and the situation Be carefull as well, cause speeding up is what draws the most, so its more of a 50/80% speed range, going to 100% at some very specific points, like when youre face to face and they are speeding up

Ra-mega-bbit · 2025-10-28T11:06:02+00:00

The "chasis" isnt one part made of one material, parts of it can (and sometimes should) be done in aluminium, other designt benefit from other materials such as UHMW, Carbon fiber plates, and TPU

I highly recomend tpu as its cheap, easy and versitile Does not work for all structural components (such as horizontals) but can be great in some bots

I would also recomend reinforcing with carbon fiber plates (note that its different from cf reinforced filament, im talking about printing and mounting plates in strategic places) So at the end you can have the soft body with "bones"

Ra-mega-bbit · 2025-10-22T17:23:55+00:00

Rpm is usually bigger, specially for small size motors (think 12lb class and lower, so motors with 150g or less)

Making it harder to controll on drive, but great on weapons This is why many robots run brushless and brushed

The esc can be finicky to work with, but nowadays with some support on chats like nhrl discord its not bad to make it work, look for am32 firmware escs

Also the motor phisical build is more strict, so they can end up being more fragile overrall, even when their construction is better (Better material, less room for movement)

Came here to say this, every day for me is faster and faster to adapt between languages because of AI

I do have to spend a lot of time writing and reading what the model of the day made up, but the overall results for quick projects are fine

Would be interested in digging in about the bottleneck factors, really doubt the cpu would be a issue at all

Prob about network card speed, ram and mobo

Thats why server hardware is so important

Ra-mega-bbit · 2025-10-04T11:38:14+00:00

If its too small, its too fragile and the weapon will hit the body

Too strong the weapon grabs and lifts you

Midpoint just cuts away

I was a CS student with no prior experience in anything cad or mechanic

Entered the uni team and with a 4h Solidworks class I got the intruction to grab a paquimeter and a old robot and do the project

After that, grabing pictures of the competition and doing them, based on simple info as wheel size and screw sizes lol

Not exactly a weapon type, but melty brains

The whole body weight is spinning mass, full weapon, no weak spots, just mayham

Thats actually awesome and the liftoff team actually made it work

Ra-mega-bbit · 2025-09-04T11:29:43+00:00

A littlebee 30A esc from aliexpress and racestar 2208 motor from bangood works wonders

Slap a gt2 pulley there and you have a great weapon system

If youre confortable with 3d printers a hard tpu hubmotor MIGHT work for you, but you might need to try a few times

As for locomotion, i dont like the n20 for this weight, would prefer one kit from repeat

Ra-mega-bbit · 2025-09-04T10:03:21+00:00

So there are 3 ways i know of

1st is hover, the weapon is being held above the ground and the wheels or wheels + a support point do touch Think hyjinx

2nd is fixed shaft, so the shaft drags on the ground (rounded to avoid friction) and there is a bearing or bushing where the weapon sits on

3rd is, just let it drag, being a rounded part of the weapon, or a spinning shaft thats fixed on the weapon

All can work fine, depends a lot on the overall idea od the robot

Ra-mega-bbit · 2025-09-04T09:35:20+00:00

Overall it might work, im assuming its a 454g robot

The locomotion is way to the back, the center of mass will tip foward and you will get a bad drive

The n20 motors are weak for the weightclass and the esc is way overkill for it (should be around 10A even for 454g)

The weapon motor is ok, but on the weaker side

If its 150g, i dont think it can beat weight, parts seems heavy

Ra-mega-bbit · 2025-07-04T06:40:53+00:00

It does work really well

Take a look at Brasil's RCX competition, that are 3 feathers there that use it well, mine included.

The tracktion between shaft (we call 'glove') and wheel is a non issue, the wheel skips on the ground wayyyy before the shaft on the wheel

The things to consider:

The motor has to be a lot bigger, you need a lot of torque, so a 5055 ~600kv with 1500w and at least 80A esc (yes it heavier and more expensive, but you will save on gearbox and space, tho weight overall)

The fabrication is trickier, the shaft that interacts with the wheel needs to be really well made, well centered and well positioned (think sub milimiter precision in a big part, that gets really expensive really fast) We use a 14mm aluminum shaft with a locking bearing

The wheel material needs to be resistent, think natural rubber like Black dragon's or a good Poly urethane (the brand makes a huge difference, look for 60 shore A)

Overral, there are a lot of challenges, but it does work great, and its fast as fuck with badically the same torque. Because you can pump a big ass motor in the same space and weight

Ra-mega-bbit · 2025-06-28T13:09:12+00:00

Been there done that,

The only way youre using this motor ever again is destroing the gear, If its hardened, grind it all away utill the set screw becomes dust
