Theoretical Robot suit

This topis is for dicussing a suit that someone could build that would be like HAL and the military one we saw.

This is if I had some sensors to feel muscle movements. I have seen some that I could make for less than 30$… I’m not sure if they would work propely, I would have to build it and test it (using a tiny leg with some normal servos I have)

I was thinking, let’s start by the legs. To add some power to the human body, the suit has to be able to lift itself plus some other weight. So let’s say you have 3 motors or servos per leg. One in the anle, one in the knee and one in the hip.

I don’t think you would need more because those are the major points with stress (rotating you leg and lifting it toward you shoulder doesn’t requier to much strengh, even with some load on your back. )

I saw some industrial servos with 5184 oz-in power at 9A and 27.5 oz.

I also saw servos with 1666 oz-in power.

Then you would have to had control boxes (assuming your plug in wall outlet :laughing: ) and some metal “Bones” between servos.

Do you think any of those servos will had enough power to be actualy usefull to have the suit on?

Thanks, Sam.

5000 oz-in is about 26 foot-pounds, which is nowhere near enough for a knee joint on a human-exoskeleton.

You would probably need 10-20x that torque before it was useful, and probably 50x that if you want to be able to do heavy stuff a person can’t do…

You mean something like Ironman? :stuck_out_tongue:

yeah, aka fantasy. :unamused:

Everytime someone brings this up I always think of letourneau-inc.com/mining/index.htm

diesel electric propulsion, and hydraulics for the lifting.

a small turbine + generator + hydraulic pump might work great for a wearable suit. Batteries don’t seem well suited for this purpose.

Course I don’t know where to buy a 5-15 HP turbine…

Don’t be to sure about that, it will be coming some day, Were pretty far with this anyway :

and also youtube.com/watch?v=OTHyv027Pb0

See that. Of course it can’t fly, but still it’s a beginning. I don’t want to make an Iron Man :laughing: :wink:

I think Hydrolics are wayyy to strong for human movement, wouldn’t liek compressed air do? Like the Air muscle we see from shadow compagny?

This is a “Project”?

Also there is a very recent thread on the same subject:

Yeah, kinda,

I want to see if I could be able maybe to just slightly do maybe something like that, much less complicated thought.

Some people know where rotation pneumatics or straight could be bought? I can’t seem to find some.
