    Hey all! Someone pointed out that this community exists, so I thought I'd jump in and share my project.

    My brothers and I have been working on a 2-DOF motion simulator for VR (see the attached pictures).

    IMG_20171227_095119.jpg IMG_20171227_095137.jpg

    Some system specs:
    Max rotation: +/- 45 degrees pitch and roll
    Max rotation rate: ~ 30 inches / second
    Actuators: 2.3 kW servo motors driving timing belts, connected to linear guides on rails.

    It is currently controlled via a PLC, which is in turn connected to a simulation running on a PC. We intend to replace that with a custom control board so that we can do more complex motion profiles at the hardware level. But that's a project for later.

    I have a video on Imgur and Reddit, but couldn't link to it because the forum thought it looked too much like spam. :-/

    Yeah, that's the one! Thanks! I have a longer video on YouTube, but same problem. I'll post a link later, when I have a few more posts to unlock links.

    Very awesome project! What model of motors do you use?

    Thanks! We used two 2.3 kW servo motors. Part number 130ST-M15015. I'd post a link, but I'm not allowed yet. :)

    Hmmm... It's definitely an unfunded, unmonetized DIY project right now. But we do hope to bring in some money with it someday. We may open source it and sell kits and parts, or we may build and sell full simulators.

    Your intention is to go the professional route, a tad too much for the DIY section ;)

    Because you "do hope to bring in some money with it someday" it falls under the commercial/prototype definition used here: https://www.xsimulator.net/community/faq/commercial-related-use-of-simtools-and-prototypes.173/

    The reason is disclosure, so members know what they may be contributing to.
