I have a need for a FAST linear actuator of which I may control position and speed reliably. I have already been looking into pnuematics, however it does not seem that this will fit my needs (I am open to suggestions though).
Currently my wanted motor specs are:
- about 1lb of force
- Position control
- Speed Control
It seems that I may be able to make a DIY linear if you will, however I wanted to ask the forums for a sanity/experience check.
Below is a rough drawing of what I was thinking to create.
- I am able to close the loop with position (looking at hacking a caliper for this or maybe even some Linear Pots in parallel, Source Link to Calipers for positioning data)
- I have a micro controller fast enough to process this position data (I believe I will be using a STM32F series but sill up in the air on this)
See the picture below for a rough outline of how I am hoping to accomplish this:
I will be controlling this with an off-the-shelf ESC.
In addition to the ESC, I will also be buying a ball screw assembly to be used as seen here - Lead screw assembly
I want to get feedback for this idea and anything that experience has shown may not work. This will be my first stab at this sort of project, so while doable it does seem like it can get big quick.
I am worried that I might be attempting to reinvent the wheel here, so what I was hoping to get is feedback on this idea or an alternative.
Thank you all in advance.
