Showroom 2DOF “Seat Mover” - Kangaroo, Sabertooth and 2x24Volt Wheelchair Motors

Good day fellow “motion simmers”.

I have been a long time simmer and have over the years refined and modified my sim rig to support both racing as well as flying simulators.

With the necessary persuasion from a good friend and fellow simmer (Robbie Teengs), we have decided to take the next step in our simming world and that is the world of motion. The decision was to start off with 2 DOF seat movers.

P.S. The matter was further complicated that I'm located in the UK and Robbie in South Africa. TeamSpeak and TeamViewer will over the past few months prove to be invaluable for the two of us to share ideas and our experiences. I'm slightly behind Robbie's project as he was able to fire his up already and apparently it is an amazing experience.

We decided to both use a similar setup to make life easier for the both of us as neither have any real electronic experience. We’re using an identical setup comprising of a Sabertooth (2X32), kangaroo, 2x potensiometers and 2X24 Volt wheelchair motors.

What will follows below is my expedition in building my own motion rig.

I’ve set-up a mock-up to familiarise myself with the basics of the Dimension Engineering Kangaroo and Sabertooth.

My 1st goal was to see if I get ant response from the wheelchair motors and I performed an auto-tune directly on the Kangaroo

And there is life !!!!

The "electronics" are coming along nicely.

And the final product.

I assume the "proof will be in the pudding"

The electronics was the fun bit. Now for the hard/dirty work.

This is a complex build as the "seat mover" mechanism needs to fit into my existing rig. Space is limited meaning that the mechanism must be compact.

It all starts by putting my ideas to paper (This is due to change as I progress with the build)

The concept is starting to take shape.


Still a long way to go. The motion mechanism will eventually bolt into the existing rig (visible in the backgrounn)

That's some damn clean wiring! Nicely done! How much is that PSU rated for?

Hi Tim. Thank you for the compliment on the wiring. The last time I've done something like that was around 40 years ago at school.

The power supply is a "SANPU 24 Volt LED Power Supply Driver 600 Watt Constant Voltage"
