EMG signal to control motor

Good morning every one. I am  current final year student in mechatronics engineering


My project is to programmed and control a motor which is a part of lower limb exoskeleton using 2 majoir components  Myoware muscle sensor and NI myRIO
 
My current status now is i can have the processed RMS value of EMG signal means that my emg signal is amplified, rectified, and integrated signal( thanks to myoware muscle sensor)  so i guess i dont need to do any filter or stuff like that and it's straight away .
 
However after that step i'm now stuck at ''the RMS emg signal value must be converted to a signal controlling the exoskeleton actuator'' and unable to process to next step especially in programming with labview because i'm not an expert on it ( a true beginner to be honest)
 
Life is hard as the school forces me into the field i barely know but i guess i gotta move on and try to complete this project anyway . What's they want in the end is i can use that signal to control the motor for lower limb exoskeleton ( just simple standing up and sitting down action or in the way i understand is use that signal to rotate and control the speed of the motor)
 
I have exactly 1 month left to finish my project and posting here is the last thing i can think of cuz i have been reading info from internet for past months.
I have the powerpoint file stating what i am doing so So anyone can give me a hint what to do next ?
 
Much appreciated if you can help 
Best regards

You know, it would be far simpler and faster for you to simply send us the e-mail address of your instructor so that we can send "your" solution directly in to him or her.

 

The Forum is not intended to do your Class Project for you -- you won't learn anything, and when you take your first job and they see you learned nothing in school except how to crib from others, your rate of advancement is going to take a hit.

 

If you really want help on the forum, don't attach the problem, attach your solution (in the form of LabVIEW code, either a single VI or a ZIP file resulting from compressing the file folder where you have saved the LabVIEW Project file and all the related VIs).  You do know about using LabVIEW Project, don't you?  You do know about using (a lot of) VIs, don't you?

 

It sounds like you next task is to drive a motor for the exoskeleton.  You know (and haven't told us) what kind of Motor you have, and presumably what kind of signals are used to control it.  From your PowerPoint file, I'm guessing the motor is a stepping motor driven by "something", possibly digital pulses.  You also have a myRIO (I think) that has quite a few output protocols for handling multiple kinds of instrumentation -- match the gadget driving the motor with the appropriate signals on the myRIO, and learn how to program that functionality.  A good source for "How do I do That" are the examples that come with LabVIEW, not to mention tutorials on the Web.

 

Note that you probably will not find a tutorial that tells you exactly how to control your exact motor -- you are going to have to do a little work.  Life is hard on all of us, but those of us to make the most of being "forced into the field I barely know", but buckle down and learn it (to the amazement of those who said "You'll never be able to do that!") usually do all right, and have fun along the way.
