Hi, i’m new to the robotics field and need some help and guidance.
I want to build a two rail linear actuator, where it would run forward on rails about 25% of the way then stop, then middle part will have a stepper motor to turn about 90 degrees and go back to starting position, until it reaches 100% of the distance. This might sound confusing since I’m knew, please see the picture below: I just want to know what software and hardware I should use for this project, any help will be much appreciated.
Unfortunately there is no image attached. Can you give us an idea of the force on the linear actuator, what stroke you need and how you want to control it?
For some reason I can’t paste my picture in here. Basically I want to make something like this: youtube.com/watch?v=Ed9nNlQQQSE even though it’s a CNC machine I need something a bit simpler. I would like an aluminum box to glide along two 2 foot rails (running on dc motors) with a stepper motor attached to the bottom of the box, so it can rotate about 90 degrees every 25% of the distance that the box moves. Then I would like the box to move back to the starting position and do the same thing except go 50% of the distance and so on until it reaches 100% of the distance. Does that make sense? I would like to be able to push around 5lbs
You can add attachments to the bottom of the reply window.
You’ll need the actuators themselves (with position feedback such as potentiometers), the controllers, and a microcontroller.
Could you tell me all the components I would need to build this? Is there a circuit board out there with software, that makes it easy to program the commands? I have no programming skills either.
This is entirely custom. Unfortunately we only carry one 24" linear actuator with position feedback: robotshop.com/en/24-stroke-5 … uator.html
This is why most people opt for a $20 stepper motor + lead screw solution.
If you do decide to go with this approach, you would need a ~15A dual motor controller and microcontroller.
For the stepper, you’d need a stepper motor controller.
