2DOF Aluminium Profile Rig

Thanks @wannabeaflyer2 thats really good to know ,,,,last time i checked i was 76 kg so it would be handy if they are good enough to use with a seat mover,,,,,,i'll have a good old wander though your thread and check out whats the best way to go regarding motor controllers and what not,,,

Thanks again for the info mate,

Will Post a picture tomorrow of my test set up for the 2DOF based on using my other set of Electric wheelchair Motors , Same as ones mentioned above , using @Wanegain Arduino Sabertooth Code ..

As for wadding through my Post LOL have fun . cos as you know by know , im a use a thousand words when two could sorttta poster do LOL ( see I Told you so )

Nice one @wannabeaflyer2 ,,,,would be cool to check your 2dof out

your 6dof looks really impressive ,, i've become pretty addicted to going though peoples build threads,, so too much info is a good thing ,,lol

Well my O-ring kit finally arrived today so was able to check if my pots were going to turn ok with my 3D printed bracket & spool ,,,everything turned like clockwork so hopefully they will work ok when i do some tests,,
By the way those pots are super cheapo but just wanted to test the theory before i get any decent ones,,

Just going to be putting 12v though the motors with the Ard + Monster Moto for now until i get a sabertooth.

Wooohoooo ,,,,,,lol ,, i got everything connected and linked up to the PC tonight using @RufusDufus SMC3 ,,and after a very basic setup in Simtools & SMC3 i got to see it working in game ,,,i know its only the motor's moving but i'm feeling on top of the world tonight

I guess the next step is to sort a new seat and a U-joint,,



P.S the guitar pedal is just a paper weight for the Ard usb cable,,,

@stevemontuno just a word of caution on your pot mount system. The way you have them connected to the output (rubber o-ring) puts a great deal of side force on the pot shaft. This could kill them early. A direct link on the other side of the gearbox might be safer and more accurate.

Flex coupler's FTW!!!

Cheers for the heads up @Historiker ,,,There isn't really much force coming from the O-ring's to be honest ,,but i guess they are going to be doing a hell of a lot of work so i might try drilling the center of the axle this weekend and mount them like you say,,, thanks for the input dude,,,

On another note i was wondering what metal are most folk using for the axle arms,, i bought some steel to use but as it's quite heavy stuff i was wondering would i be better using aluminium or is ally too soft,,?

I would personally recommend steel but if you have a very very tight fit aluminum might work out. Just think of all the violent reverse movement that the joint will undergo.

Or, make a u shape for your pot where the pot arm goes through it and its supported on both sides.

Cheers @noorbeast ,,,i think i'll order some ally too then as im about 73kg

3/4" Round from the Local Hardware store is all I used, Not too thick, Not too thin.

Just a few minor updates ,,,,,

I made a couple of paddles for the motors,



Also went to the scrappy and picked up a Propshaft , just waiting on my mate to come round now with his welder so i can weld it to some steel plates,







Put a heat sink and 12v fan on the monster moto,,need to grab another MM and do the same again,,



Also tonight my bro came round with another 6 motors for me , 2 of which were the 24v ones with the 30/1 gears , but 4 of them were 12v motors on the same type of gears but 25/1 ratio 3 of which were really big ,,
The specs on the large motors are ,,12v , 15amp ,, 150rpm ,,, and 200w ,,it doesn't mention the torque ,,they are pretty beastie though and also have a bracket on the back of the motor for support,,,



This might interest you @Nick Moxley ,, he said they are off of a TGA power pack for electric wheelchair,,the larger motors have 2 wheels attached to them,, the smaller ones having 1 wheel,



kinda made my day seeing 12v on those motors ,,,i'll be putting those on the 30/1 ratio gears.

Nice find for your Brother and yourself.. Thanks for posting.

My new seat came yesterday,,, i can finally start to take measurements and work out where things are going ,,,,it feels like i'm slowly getting there now,,

Oh no they look like fun !!!

Good ! What size screens ?

My monitors are 23" ,, i can't really go much bigger as my rig is in the living room so im trying to keep it compact,,,,,,i don't want to p!ss the missus off ,,,,lol ,,she's cool though,,,

Oh my how motion will change how you drive in Dirt, hehe Im glad i learned Dirt With motion, I could only imagine getting the hang of thing's without, then being thrown into the lions pit with a properly setup profile in a Fast seat mover.....oh me oh my.
