Hydraulics like steam are extremely powerful but the downside to both is that they generate a LOT of Pressure and Heat.

Heats usually a bad thing,  but pressure is what you want.   its "pressure" that pushes your widgets and things around.

Locksuit, it could be anything, its just a moving arm.

Just do it for every axis of your robot,  and its the motor controller.    u can use it for anything, because robots take many forms,  a car is a robot, any machine is, if you want to look at that way.

Its its body,  not its brain,  But I have the most awesome idea for a brain!    but people wont even believe me, because everyone thinks we are on such clever stuff already ill keep it to myself. ;)

Constructing a robot framework is really the "Easy" part...
After all, without a Brain, it's just a glorified Paperweight!  ;)

and let them all fail like the bible.   with great self appreciation of how s**t they are.

Who cares how many sensors the body has, if it cant even do the simplest thing.

Sources for one's hobby/endeavor are always nice to have so I've taken the liberty to do a bit of searching in an effort to provide a few additional ones.

While this listing might be a mixed bag of tricks, there's sure to be something for everyone interesting in learning or experimenting with robots/robotics.

I had a look,  and the motor connectors look interesting to me,    but someone just brought some tin snips around and now im going to make the brackets myself. :)

Got a more solid prototype of the jointy done.

Nice improvement over the paper one!

A true Universal joint as in a motor vehicle drive shaft would or should provide 180ยบ of rotation. Affixing drive motors to the 4-way joint, however, might prove to be problematic I would think.  Then again it's your design!  O0

Thanks art. :)

its shy off 180, its about 145?   because of the back bracing - but i need that because it would be easier to break it without it.  But i might regret that later,  im not sure about it.

This isnt the final one,  but its my first taste of using the nasty metal, i had a bit of a sick high after i got it done   :D

i cut myself a little bit but my friend had some sand paper luckily so i got rid of most of the burrs before i bent it into shape.

The new one is going to be much smaller radius and still keep the 145*.   if u notice there is a large radius outer ring, and a small lobe on the back, and it actually can be alot smaller than it is,  so im going to start again even better.


The next one, (version 3) is going to be mounted by a self tapping screw into the front of the motors, and that will be ALOT stronger than the crappy soldier job on it now

Also should have pipes bolted to it,   but im still not sure what to do with the cross fitting,  its still just a blob of solder.

So it has 2 motors (2 axises of rotation)?

How much did it cost to make that?

Because online I'm always seeing/hearing that arms with only like what 6 motors are over 15,000-80,000 dollars which annoys me because my logic tells me the Dollar Store has 1 dollar motors which makes NO sense whatsoever!! Lol.

Its cheap (my one)  its $5 a hobby motor, they have "low torque" on the description for them.  Ill have to see how they go,  i havent actually wired it up yet - except that broken linear drive,  but on that they seem to be too powerful! :)   not sure, until i finish it for real!

I dont think i could stand on it, and ride off into the sunset, but im pretty sure itll be able to lift itself easily.

But those $80,000 arms your talking about are finished products,  so the price does go up for a full finished unit.  Its because its ready to go manufacture (if u know how to use them.) straight out of the box,  so the price would be higher.

So if I want an arm with 6 motors (3 rotation, 3 location), how much could it cost if I have a freelancer make it? 1 8th the price?

Dont like your chances,  when I was on game programming forums people that tried to get people to code games for them didnt have much luck.  ;)

Your best bet is to get a 3d printed kit,  and go order a print done for you.
They dont print robots out in one hit yet,  you have to post assemble all the parts.


https://3dprint.com/106725/wednesday-roundup-ten-3d-printable-things-awesome-beginner-3d-printable-robotics-projects/   

theres a page,   they are a bit beginnery,  but it would be a good place to start your search.

Ranch said, "For the simplicity of doing it that way"
That way being the Engineering Design Process.

Good success is my prediction.  Thank you for sharing.

Just adding, the material (other than hand-drawn)
posted to this thread is quite interesting as well.
