Since the first pi came out I wanted to build an exoskeletal suit. Just thick 3D printed ABS (or PLA) with small steel supports and a the rediculous number of stepper motors. Along with a huge Li-ion backpack and a pi of somesort.

Keeping the suit which is just framework basically, 5% lager than the body and jsut have it mirror the movmeents you do inside of it with pressure sensative pads, making it want to keep you direclt in the center. So when you mvoe your hand it touches the inside of the palm. It moves down with your hand until the pressure eases off.  etc etc.

Of course its entirely theory as I wont have the money for usch an endevour for many years to come. Would certaintly be a fun project though

Waouh !! What a project !!
I guess it need a lot of knowlegde about robotics & programming, and for sure... some funds!!
Good idea indeed.

Funds is the only real issue. Of course usually endeavors like this would cost a lot more because nearly all of it goes to labor. Scientists charge a lot after all.

You never know when a grant will spring up though. So maybe one day.

This isn't my actual project just a discussion. I could never do this unless I won the lottery, too expensive of a venture.

My project was the orange topped pi. Which was a high battery life laptop basically running wheezing.
But the project is pretty well dead. Its been 4 months since I started it and without the orange pi hardware that is a dead end street.
The project was completed with a Raspberry pi 2 and ended up with 35 hours of run time playing videos on a single charge. But I cant exactly release a tutorial that was intended for an orange pi board without an orange pi board. and the raspberry pi one has been done before. The entire point of this was that it would have a solid state drive and only boot from the SD card. which required the SATA connector the orange pi had.

Really interesting discussion going on there. What are your plans for it? And speaking of stepper motors, why not servos? They're easier to control with fewer pins, and less costly as you don't need a separate driver. And as for the decision of using a SBC to control all that is.. bad, I'd recommend a MCU (a cortex M0 atleast)

well dude nice thinking.
1) I would like to tell you that you need to learn some of rotational motion physics as it will be highly useful in building all the necessary mechanics " determining torque
   and forces at different position in your suit".
2) you should not use stepper motor for this project as you might be needing a huge amount of torque at every step if you want you suit to carry you inside and just walk. ans in case if you add steel or metal parts its gonna be bulky so dont use steppers.
3) man first of all find a appropriate power source as i hd too may project all cancelled due to lack of power source. as if you are going to put a hell lot of your time making project and it works only for few minutes. you wont be looking forward to that. SO FIND A PROPER POWER SOURCE.
