Project Log 48: 3D modelling attempt 3.

A project log for DIY Mech/Exoskeleton suit.

Mechs are not viable, nor cheap, so I will try to design and build one alone anyway.

Sorry for the delay, I was trying to make something these last days, but for some reason, I just can't.

I just stare at the 3d modelling program and I just can't make anything out of it... :/

I'm still trying right now tho...


Good morning.

Right now I should be be preparing myself to do something, but I'm procrastinating.


Anyway, while I was trying different types of wattages and motors on those "Torque to HP converter" and "Pulley Ratio calculators", I noticed that I would just need an 900 RPM electric winch actuator since I would treat the limb itself as a pulley; and thus, the distance in which the cables are attached to the limbs accordingly to its axis of rotation will be more or less the diameter of a imaginary giant pulley.

(I need to remember to make an illustration showing that)

I hope the illustration is clear enough.

Also, I can't believe this, but I'm actually considering using the goddang micro servo motor "muscle" I suggested on Project Log 1.

These can use around 10 watts of power, but depending on its RPM, I would actually need half of it per motor.
Some websites sell these motors with a rotation speed of 60 RPM, others as a 300 rpm. Dunno which is true, but hey... As long it is cheap...


I literally made more than 40 project logs just to go full circle and reach this stupid conclusion...

I hate myself...


Of course, before I definitely go through the winch path, I will try just one more time.

Because I feel like I didn't try enough with this rotary hexapod.

I found this "rotapod" from this website where multiple disks are stacked together.

I tried this configuration at the first time, but it ended too big for my taste (bigger than the previous attempts). But I will try with a more moderate sized parts and see where it takes me.

Too long...

Did it more like the first image. Kinda bulky tho...

Yeah... Too bulky...

Winch it is...


Of course, I won't be doing the exactly same idea I had before with micro servo motors, simply because those aren't fast enough.

Because the arm will be a giant pulley and so on.
