A 7 function manipulator...
Don't get excited, I haven't built one yet. But i'm playing around with a few ideas for one.
After seeing Steves 3D printed manipulator and ROV Reboot(all hail Steve Thone), i thought about making a whole arm. I
made a mock up out of foam to give me a starting point. I looked into different ways to power it and I'm thinking of going hydraulic.
I bought a ram, pump and valve from http://www.magomhrc.com/en/13-hydraulic-parts to play with.
If any of you have any ideas, post them.

Re: A 7 function manipulator...
It looks like you are the right track. Those RC hydraulic systems seem the way to go.
I am sure you already know about this one:

What do you expect this to cost?

Re: A 7 function manipulator...
The rams are about $55 and the valves range from $70 for one to $210 for a six way. Hopefully will only need one pump.
The arm itself shouldn't be much if it's printed. Of course I still have to buy a printer and learn how to design and use it.

Re: A 7 function manipulator...
Will you have to build a housing for the pump? I wish the stuff was cheaper but it is very specialized. Looks like it will be a $1000+ project but I guess that is cheap compared to commercial stuff!

Re: A 7 function manipulator...
The pump and valves will go in a wtc and run the hoses out to the arm. I'm still working on how to rotate the arm and claw and actuate the claw. I'm thinking maybe a flexable shaft, like a bicycle brake cable or Dremel flex shaft.
Magom sells the individual parts for the rams, so anyone with a lathe could make their own cylinders and shafts and just have to buy fittings. That would cut down the cost.

Do they have hydraulic rotators? I know there are pneumatic ones.

Re: A 7 function manipulator...
Finally got the pump and valve hooked up to the RC controller. Just have to connect the hoses and prime it and see how it works.

Re: A 7 function manipulator...
I got the Magom hydraulic kit hooked up to a Traxxas RC controller and installed it on a foam manipulator mock-up. I think this might work.
