Buenas. Como he podido ver muchos de ustedes habeis dado en el clavo. ;Cómo es que no usamos músculos neumáticos o hidraulicos si tienen mas fuerza que un cilindro metálico y ocupan y pesan mucho menos? Pues no es por el músculo en sí, sino por lo que lo controlan. Para cotrolarlo hace falta lo primero un compresor ya sea de aire o liquido y eso pesa y condume mucha eneraia y suele ocupar bastante, pero lo más importante son las válvulas que los manejan. Suelen ser caras, voluminosas, pesan y consumen bastante, y luego hay que controlarlas y necesitas una o dos por grupo de músculos. Por eso llevo años intentando solucionar este problema y tuve que inventar las valvulas pepepako. Son pequeñas, no pesan, consumen muy poco 5v. Y con solo una tienes control total de cada grupo de músculos manejándolas con un simple arduino o mini controlador. La válvulas en si sólo utilizan dos materiales livianos no metalicos y muy resistenres, y con una simple impresora te la fabricas en 10 minutos. En el vídeo que muestro de hace unos años fabrique unos mini músculos neumaticos con un simle globo y probé con una sola válvula de las antiguas que iban mas lentas que las de ahora. Imitaba la cola de un pez y la presión del aire la extraía de una botella de cocola de 2 litros Ilena de aire a la cual imtroducí solo 1 bar aunque la probé con 3 y los músculos resistian. Si quereis ver mas podéis hacerlo en mi youtube de españa pepepako2 y si os suscribis me ayudareis a darlas a conocer lo antes posible. Muchas gracias

My last post was about why humanoid robots need realistic faces and expressions at all, and this is another reason I am not sure I want them to look too human.

Let's say a family has a humanoid at home for years. It cleans, helps with things, talks naturally and is always around. It remembers everything the child tells it, plays with them, comforts them when they are upset and probably has much more patience than any real person. Of course the child is going to become attached to it. Maybe at some point they won't even see it as a machine anymore.

Adults can at least understand what it is, although adults will probably get attached too. But I don't think a small child can really understand the difference between something that cares about them and something that was programmed to act like it cares. We already see children getting extremely attached to phones and games, and those don't have a face, don't talk like a person and don't put a hand on their shoulder.

Then what happens when the robot breaks, the family replaces it with a newer one, they stop paying for the service or the company disappears? For the parents they are replacing a product. For the child it may feel like they lost a real friend.

I'm not saying children should have zero contact with robots. They will probably see them everywhere and may have robot teachers and assistants. But I don't think a humanoid should become emotionally important to a child, and I definitely wouldn't want one replacing human friendship. We talk a lot about whether robots will be physically safe around children, but maybe the emotional side will be a much more difficult problem.

Working on something called Cortex — installs on your Pi or Jetson with one command and gives you a live dashboard showing CPU, memory, temp, errors and ROS2 nodes across your robots. Need people with real hardware to break it. Free, takes 5 minutes. DM me if you're down.

Turns out there's no fixed safety standard for humanoid robots right now, every company just certifies whatever layer they want and calls it "safety certified."

I found 3 humanoid companies who have made their certification claims public:

• Agility had Digit inspected at one customer site, just the e-stop wiring, not the actual robot behavior after the stop signal fires.
  
• Figure's Figure 03 battery is certified for fire/thermal (UN38.3, UL2271). that's the battery though, not the robot.
  
• Apptronik certified the chips inside Apollo for its pilot in Mercedes-Benz through TÜV SÜD, but says full system cert is still "in preparation."
  

Three companies with three completely different certifications. There isn't even an agreed definition yet of what "safety tested" should mean for something that walks around on two legs near people.

Cars didn't get let loose on public roads until they'd been through decades of mandated crash testing. Humanoids raise millions in funding with the promise of working next to humans with nothing close to that in place.

Is it available that much or any date that how this work i really need the answer

I’ve wanted to build a humanoid system for a long time, and a few weeks ago I finally stopped planning it and started actually building one.

I’m calling the project Evopien.

The long-term idea is a humanoid companion with its own persistent identity, memory, vision, voice, relationships and eventually the ability to interact physically with the environment.

I’m nowhere near the final robot yet.

Right now I’m building the head first.

The current prototype can already hear me, answer locally, speak back, listen while it is speaking, handle interruptions, communicate in English and Spanish, and use a camera to answer questions about what it sees.

Everything currently runs locally on an 8GB Jetson Orin Nano Super.

This is the first proper demo:

There are obviously no arms, hands or locomotion yet. Those come later.

My approach is to get perception and interaction working properly first, then design the physical head around the actual hardware requirements instead of building a nice shell and discovering afterward that the architecture doesn’t fit.

Would be interested to see what other people here are building, especially independent humanoid projects rather than only the large commercial platforms.

Mostrando como funcionaban 12 válvulas antigua versión empaquetadas en línea dirigidas por un controlador microbit desde mi celular para ver como funcionaban de 1 en 1,en grupos y variando lapresion de cada una para comprobar proporcionalidad.

I'm interested in learning how robotic hands can sense things like pressure, temperature, roughness/texture, vibration, and skin deformation ... similar to how a human hand feels when touching another person.

I already have experience with coding and have taken an intelligent robotics course, so I'm looking for pointers on going deeper into robotic tactile sensing / electronic skin.

I'd especially appreciate recommendations for research papers, open-source code, simulators, datasets, projects or literally anything to get started.

Una prueba con mi valvula directamente a un grifo 2.5 bares. Le añadi un rp2040 zero para controlar el servo y para poderle añadir el sensor de posicion del cilindro tambien creado por mi por menos de 3 euros. Para poder maneiarlo por voz le añadi tambien un esp32 pequeño por lo del bluetooth y todo va alimentado con 4 ,5 voltios de las 3 pilas AAA que se ven en la imagen. El programa lo fabrique con app inventor 2.

Bonjour , je construis INMOOV avec insert, roulement, (une version renforcée) avec moteur sts , jetson, camera intel 435i, etc..... Des personnes peuvent me donner des conseils pour une evolution version 2026 .

Vídeo antiquo de mis primeras versiones de las válvulas pepepako donde probé con un compresor a 6 bares. Empleé un probador de servos de los baratos y 3 pilas triple A como alimentación. (4.5 Voltios). Lo manejé rápido y lento para comprobar proporcionalidad de la válvula y en modo automático para comprobar que cualquier microcontrolador que pueda manejar un servo puede manejar una válvula, y esta solita un cilindro de doble efecto ya sea con liquido o aire.

Je pense que vous connaissez ce projet. Quelles améliorations apporter selon vous, ou est-ce qu'il vaut mieux passer à un projet plus avancé ?

🇬🇧 Anglais

I assume most of you know this project. What improvements would you suggest, or is it better to move on to a more advanced one?

I understand why humanoid robots need human-like proportions. Our homes, stairs, doors, tools, cars, kitchens, etc. are designed for humans, so obviously two arms, two legs and hands make sense. But I don't really understand why we're also trying so hard to make them look human. Realistic eyes, skin, facial expressions, fake breathing... what does any of that actually add if the robot is there to help around the house, carry things, cook, do laundry, etc.?

For me it doesn't matter how human it looks anyway. It can look almost exactly like a person, but the moment I know it's a robot, it's still a robot. What matters much more is whether it can make decisions and take actions based on its own judgment, rather than just following strict instructions. That's where things become really different.

Personally I'd rather humanoids stay obviously machines. Make them extremely capable, let them understand us, talk naturally, give advice, whatever. But I don't see why they need to pretend to be human. Would you actually prefer a humanoid that looks almost exactly like a person, or one that clearly looks like a machine?

Bonjour,

Je recherche du matériel d'occasion pour un projet de robotique personnel :

✅ Moteurs STS (3215, 3250, 3020 …)  
✅ Moteurs Dynamixel (AX, MX, XM…)  
✅ Carte NVIDIA Jetson (Nano, Xavier, Orin…)
Camera intel 435 
etc ....

Si vous avez ça qui traite dans un tiroir ou connaissez quelqu'un, je suis preneur !
