    Hello everbody,


    I would like to introduce my motion project. It is basically based on a sabertooth 2x25A motor controller and a kangaroo V2 by Dimension Engineering.


    I managed to tune the controller combination successfully, so it seems to be a closed servo system by now.


    The motion platform is build on wood, but stable enough to move and carry the full payload of a Flightsimulator.

    On the bottom I used a tyre to carry the most payload. In the front there are two electronic actuators which can handle the movement without no problems.

    A bit slow, but enough speed for an airliner.


    The position feedback is solved by a diy linear range potentiometer, in order to give feedback of the full travel range of the actuators.

    I hope that my project can help some guys to find their own solution.

    Thankd for sharing your project.

    Out of curiosity what are the actuator ratings and speed?

    I know my project is a bit different. But my problem is the heavy payload. 500kg min. I tried before with wheelchair 350watt each. It was too difficult to handle with all the amperage. The wires were glowing..
    So I decided to draw back.
    The actuators have 12-24 v. The can push and pull 5000N. So I decided to Swap the Center of gravity on the tyre. This means to relieve the actuators a lot. Therefore they reach the full Range of 10cm in 5-6 Seconds.
