they arnet heavy, they have magnets that stick themselves to the floor

Actually, the sport has weight classes, like boxing

​@kayrunjaavice1421 is it legal?

D4RKBRU73 straight facts lmao

Yea

Tijan that and the strong ass magnets keeping them on the mat notice they use a pry bar and wood to lift them up

Tijan there's a great amount of programming and coding that goes behind this as well

Tijan i don't think humans directly control the robots just program little ai into them and let them duke it out

That is how the sport works, if I'm remembering correct. The robots get a list of commands and simple logic patterns [I use that term loosely, it's still quite a lot of code] and then they both hit go at the same itme basically.

They're autonomous in that they have active sensors which let them scan and plot their environment and respond and react to changing stimuli. They can do it incredibly quickly. The Builders can set their basic strategy beforehand, which determines whether they'll attack head-on, from the side, try to get behind their opponent, wait to be hit first, move very slowly, or go nuts before the other robot has got its bearings. You can see the last second decisions being made in secret just as the Builders place their robot on the arena floor. They try to pick a strategy their opponent won't expect, and sometimes you can see them deliberately hide their final programming button press behind their free hand. Once the robots are stuck to the floor (they use sheets of ridiculously powerful neodymium magnets), they're on their own. They can sense their opponents; they can sense the edge of the arena, and they can adapt to the attacks of their opponents. Watching them facing off and making tiny, nervous, jittery moves reminds me of two wary jumping spiders meeting. They're looking for a flaw in the other guy's programming, and trying to react to that. When they both do it together it really does look like they're 'thinking'. I suppose they are. (Er, better ask a philosopher about that!) The speed of reaction is beyond anything a human could manage, which is what makes the sport so fascinating to watch. I'd love to get involved, but the programming and electronics is way beyond my tiny brain. :-)

They are not angry *THEY ARE A N G E R Y*

Smash that ass gaha

Omar Gonzalez Se utilizan sensores de luz para detectar las esquinas. (Lo siento, mal español)

Like what type? Como que tipo?

Omar Gonzalez they use an Infrared Sensor to calculate how much light bounces on the surface: White reflects more, Black reflects less. Then they calibrate it to the right range of numbers.

Cem Nurlu Ohh Okay' thank you very much is it like the CNY70 Sensor?

Omar Gonzalez yeah, just more expensive and fast.

Henry Levine the bed is metalic. Some robots are using really strong magnets to attach to the ground.

Is that allowed by the sumobot rules

Henry Levine as long as your robot doesn't leave permanent scratch or damage it, yes.

si que es metalico i si que los robots llevan imanes. Los robots lentos llevan un monton de imanes

xavi puigmal pero no todos son escenarios metálicos verdad? Aqui en Argentina son de otro material, no se si todos, al menos los que conozco

Rodrigo Martinez aun hay alguna competicion que el tatami es de madera, aunque yo creo que se ira perdiendo, a mucho sitios ahora es de metal. dentro de 12 dias se celebra el all japan robot sumo, la competicion mas importante del mundo de sumo en tatami de metal, estate atento a mi canal que mirare se subir lo combates que pueda

Depende en que quieras programarlos lo más común es ensamblador o C si usas microcontroladores, pero se pueden usar Arduinos que tienen su propio lenguaje, igual depende del controlador que uses

pots participr a la categoria universitria o lliure, que no te limit d'edat

+xavi puigmal Ah. Vale no ho savia que existia aquesta categoria. 🖒 Bon treball amb el robot 👌👏

+xavi puigmal Una pregunta, amb quina bateria utilitzes per alimenta la 3pi no se si utilitzar una lipo de 1s o de 2s amb un ajustador de volts.

+Pau Serrat Artigas vigila!!! jo no alimentaria el 3pi amb mes duna lipo, ja que el robot ja porta els step-up apropiats tant per electronica com per motors

+xavi puigmal aniria be una lipo de 2s amb un regulador de tensio amb 5v de sortida? Ja que tinc antes que no ens podem pasar de 7v, no?

Si, tdos los robots utilizan el pwm para modificar la velocidad

+xavi puigmal Pero el pwm y los encoders no eran diferentes?

+xavi puigmal Me podrias pasar algun mail para contactar con tigo? Es que quiero hacer un robot velocista y necesito consejo.
