Thread: SSC-32 Controllable linear actuators?

  1. #1

    SSC-32 Controllable linear actuators?

    I was curious if anyone knows of a solution to either making, or buy a completed product that will allow linear actuation through the control of an SSC-32 board.

    I want to use linear actuators to allow 2 arms to move both left and right while simultaneously doing other things.

    I have found one solution at servo city there linear actuators that can be plugged up to any hobby servo control board. The down side is that there a little expensive for me right now $300 a peace and I'm looking for a possible solution to come out a little cheaper. If there even is one.

    Accuracy down to the mm is not totally necessary either.

    A microcontroller, H-Bridge, and slid pot might could do what you want if there isn't already an off the shelf solution. I believe Ooops is using a servo driven linear actuator.

    As with anything...make it yourself. I've scene pretty cool ones made from 80/20 aluminum, and threaded rod.

    Twist the rod using a continuous rotation servo.

    Re: SSC-32 Controllable linear actuators?

    Have a look at the Firgelli L12 series. I'm running late to a meeting, so I can't go into too much right now, but they seem reasonably priced across the line from what I've seen. You want OPTION I:

    Option I—Integrated controller with industrial and RC servo interfaces
    Wiring:
    1 (green) Current input signal (used for 4–20 mA interface mode)
    2 (blue) Voltage input signal (used for the 0–5V interface mode and PWM interface modes)
    3 (purple) Position Feedback signal(0–3.3 V, linearly proportional to actuator position)
    4 (white) RC input signal (used for RC-servo compatible interface mode)
    5 (red) Motor V+ (+6 Vdc for 6 V models, +12 Vdc for 12 V models)
    6 (black) Ground

    In fact, looks like Trossen did the leg-work already for us on that:

    Hrm Adrenalynn while those are indeed nice I'm looking for a bit more distance of travel then those can offer. Unless I'm missing something in the specs.

    And therein lies the rub. We can only scheme solutions to stated problems.
    How about something a little more detailed than "a bit more distance"?

    haha yeah that would probably help wouldn't it. Around 6-8 inches of travel would be the range.


    Now I know these exist http://www.nookindustries.com/images/nookmodular.jpgand are far beyond what i need,but is there something in that style, which i can control through a servo board. Or is a separate controller going to be the only option?

    The only reason I'm looking to control it though the SSC-32 is for simplicity reasons. I can this way control do all the work through SEQ as opposed to using another set of software for just the actuators.

    I don't see anything for less than $300.

    You know you can control a motor controller from the SSC32, right? Motor controllers talk pwm, ie. they are like servos in the control signals they take.

    Servocity has some interesting actuators. Not cheap though.

    Adrenalynn do you mean one of these? http://www.lynxmotion.com/Product.as...&CategoryID=10

    How would you go about applying something like this to a linear actuator?

    Would it be something like a rack and pinion setup or something else?
