    Hey all,

    Since discovering this community 3 weeks ago I have been scouring all the posts to get as much info as possible. The community got me triggered to work on my own motion simulator.

    Me and my father are planning to build a 6DOF motion simulator where we will try to realise the following build


    On the forum I have found that @Gregory Wood has a similar ‘low footprint’ build that he documented on https://www.xsimulator.net/communit...ct-and-no-linear-actuators-220v-servos.11839/

    Some background about us: I’m active as an IT project manager and doing DIY projects is my way of staying in touch with my development roots. Just finished my home automation Jarvis (a NodeJS server on a Raspberry PI that controls everything through KNX). My dad used to build race buggies in his childhood.

    We’ll be trying to post a weekly update as we are aiming to have a working build within 4 months (might be tight but always good to have a deadline ;))

    Just like the other posts we would love to get the community involved and document a lot of the steps so that others can also get new information.

    Week 1
    Ordered an Arduino getting started kit to learn the basics of Arduino, electronics and boards. From my dad’s 20 year old RC helicopter we salvaged the servo’s to see if we can make a prove a concept just like @hooshang at https://www.xsimulator.net/community/threads/6dof-platform-with-small-dc-motors.5634/

    First step was of course understanding Arduino and controlling some servo’s:


    We’ll now be looking at the SimTools software and building a POC 6DOF simulator just like @hooshang

    Week 2
    Finished the base for the prototype, tomorrow we'll be working on the platform that is connected with the base.
    Ordered some extra Arduino's so once those arrive I can start experimenting with the software.

    Platform has been added, now I got to wait on the delivery of the extra Arduino's ;)

    Took me a while to figure out the software and edit an existing Arduino project so I can control 6 servo's but I finally got it working ;)

    Good job so far,
    This little version of the cockpit looks to be concrete already.

    Looking at the movements it looks like you're using yaw instead of traction and the sway should be reversed I think but could be wrong but great little build

    Thanks for the suggestion, I'll look into it tomorrow.
    The servo's are also 20+ years old, they have a huge delay. For example: the servo that comes with the Arduino starters kit is about 3 times as fast.
