@astrashristi: 🤯 Who needs expensive robotics when you have cardboard, rubber bands, and a brilliant idea? This incredible handmade machine turns ordinary materials into a fully mechanical robotic battle arena — powered entirely by clever engineering, not electronics. 🛠️ The secret lies in mechanical advantage, linkages, and stored elastic energy. Stretched rubber bands store potential energy, which is released to power the launchers. Levers and carefully arranged linkages transfer movement through the machine, coordinating its actions without a single motor, battery, or microchip. Every part has a purpose. The placement of each lever, the tension of each rubber band, and the geometry of the moving components all help determine how the mechanism performs. It’s a perfect example of how basic physics and mechanical design can transform inexpensive materials into something surprisingly sophisticated. The biggest lesson? Innovation isn't about having the most expensive tools — it's about knowing how to use what you have. 🔧 Would you build something like this yourself? 👇 📚 Shared for educational purposes only. 📩 DM for credit or removal.

John Wick Low Budget

Bukan Mekanik Motor :

wait, how did it reload and fire again? the string pulls the bullet back in, but then what makes it fire again? 😳

Neo :

We need a tutorial. On how to build this

:

seriously though.. where can I buy one 🤣

5ivesixty :

US play the real life version.

Ryan :

so its rock em sock em robots?

Light. :

Now it's a gunfight? 😂

I want one !!! no seriously I do! 😳

Paul Nowak :

where do I get this?

Tom :

Totally want this!! Where can I buy this?

Joshkaelb Cabrera :

dónde donde consigo uno de esosssssssssss😳

Brian Goitia :

que alguien me mande las instrucciones para hacer lo quiero uno

play with my bro, day 1 this thing will be destroy

zee :

how to build please

Spartan0724 :

así entrenaba John Wick

I need this!

Jordi :

User_Vlad :

John Stick💪

Vanar :

This must be an American game ...

M.P :

planos?

WrefDad :

Dollar sign before number.

CaboFire15 :

Voy

Diego Andres Cruz Santa :

será que me podrian decir como se hace uno de esos

donotfollow :

that laugh 😁
