Nope, a personal project to make a mech in real life. Silly, I know, but the important part is that I have fun calculating it, even if I will never build it in real life.

I think I solved it, since it ended up as 6000 watts and the kinetic energy of 3000kg at a few meters per second. But yes, everything is outo of my comfort zone given I literally don't know anything about physics.

The calculation that I've made showed such little power to move things probably because I considered the continuous flow or air and not the instantaneous flow of pressurized gas being released. It would work like a spring, so just a few thousand joules would be used to compress it and it would...

Probably because I considered the continuous flow or air and not the instantaneous flow of pressurized gas being released. It would work like a spring, so just a few thousand joules would be used to compress it and it would release all of these joules at same time, while the wattage of rpm and...

Actually, I added because at the time I recalculated and thought it was correct, but now I woke up and saw that my math was incorrect. Now I can't edit the tittle again, lol

I tried again: When asking around I still didn’t get the answer, but someone suggested taking the volume of the initial state and subtracting it by the volume of the compressed state. On top of that, they also suggested doubling that value since in pneumatics you can only apply a constant force...

My issue is not the structure per se, it is how much energy I need to input into the system and how much energy it actuates with.

Semi-independent actuators, Kinda like filament mckibben muscles. Source: "Musculoskeletal lower-limb robot driven by multifilament muscles" I tried to simplify the problem by calculating the muscles as horizontal cylinders and then making something like in the pic. making these big things...

Well, I don't know how to go correctly, I was going trial and error. But no matter what I tried, I couldn't find the correct values on anything. I was trying to reach a bundle of filament artificial muscles with 3000 kilograms of output force with at least 5 to 10 centimeters of contraction...

I was calculating to find out first how much force it would produce, and then work with it to either increase or decrease. But I was thinking of 1/5 of a second 0.2 contraction with a constant tension force with at least 10 cm of linear movement. I was calculating, let's say, that you had an X...

Well, I was trying to predict how much energy a pneumatic system would need in order to actuate in a specific force and speed, but it seems that I would need too little energy for too much work. So, I was wondering how I would go on about making a pneumatic system with artificial muscles, they...

Essentially, a stator generates an electromagnetic field that interacts with the magnetic field of the rotor. If you had a rotor with the same winding as a flipped stator, then both electromagnetic fields would interact with each other and force rotation? Don't worry about how the rotor's...
