2DOF Aluminium Profile Rig

Hi ,

I'm wanting to add motion to my 80/20 rig and still keep the compact design so i'm thinking my best bet is to go with the 2dof desk racer style like @bsft & @noorbeast have done,,

My rig (sorry for the side on view)

I've been trying to get to grips with the whole idea by doing the @eaorobbie RC model ,, which has been a massive help in getting to grips with basic simtools & arduino settup,,,

I'm not in no major rush so i'll probably start by buying bits and bats over the next few months..

If any of you guys have got any tips and what not i'd be glad to here them,,

Cheers ,,,,,,Steve.

Edit : Fast Forward 1 year ,,,,,, Rig in March 2017

Thanks ,, i'll keep that in mind ,
i did save a link on my gaming PC to some motors on ebay from a seller in italy that someone posted up,,, they seemed pretty similar to the ones you use so i'll probably get those unless i see some from the UK.

@stevemontuno i agree with you that the very first thing before building a simulator is to make a RC servo set and get familiar with simtools and other. i like you racing seat in your miniature rig.going to replace my cardboard one with a printed one.

Yes the RC model was an eye opener ,,,,,Here you go @insanegr ,,,, http://www.thingiverse.com/thing:32318 i just increased the size ,,

thanks @stevemontuno just printed one 2:20 hours and found out it was small now i am printing new one scaled up a bit. need 2 more hours to be done.

Just a quick update,,,

I've been buying bits and bobs over the last couple of weeks and i'm almost ready to rig the electronics to the motors for a test,,,I just need to jump on sketchup and make a bracket for connecting the pots to the motors first so hopefully then i can get some testing done ,,(must be patient) ,,lol

Also i got really lucky with the motors ,,, my brother repairs mobility scooters so i gave him a call and asked him if he could get me some motors off any of the decommissioned scooters,,,,they are 24v with 30/1 gears but look alot like the ones motiondynamics sell so are perfect to get me up and running and maybe experiment a bit in the future ,, i'll get some of the 12v ones when im closer to finishing the project,, ,, hopefully i wont be taxing you guys brains too must while setting it up ,,

the 24volt motors will work specs pending. just need proper controller and psu.

Cheers @noorbeast the motor specs are 24v , amps 3 , rpm 110 , torque 2.7nm ,, i don't know what the torque equates too when the 30/1 gears are attached,,

Would i need 2x sabertooths and 2x 24v PSU's to run a 24v motor setup with the Arduino,,,,,,,,also do you know what the pro's/con's of going 24v over 12v if there is any?,,,cheers mate

that is 72 watts, 2.7nm, they may be under powered for a seat mover but the guys that build this type of rig may have an opinion. there isn't much room for a trade off (torque/speed). I know guys built them with less but 200watts, 15-20 nm is a starting point imho. again not sure for a seat mover though.

That doesn't sound like they will be much cop,,,,oh well they will come in handy to get everything up and running and then i'll buy some of those motors with the 50/1 gearbox when the canadian seller has them back in stock..
cheers dude.

Any chance of getting some more info on those motor's like what Chair they came from....those are the First Identical style gearbox to our PGsaw and MotionDynamics setup's That Isn't from one of those 2. So Im curious as to where they came from.

Also I just so happen to notice you have 2 totally different motor's/Gearboxes on the table, What are the other motor/boxes specs ?

Thanks.

Yeh my eye's popped out when i saw they were motiondynamics style ,,was a bit of a letdown when i saw 24 volts but i guess beggers can't be choosers,,lol
I'm pretty sure he said it was called the Traveller ,,don't know weather it was a lekky scooter or wheelchair but he said they are a pretty old model,,,i told him to grab me some more if he ever see's any,,,,

The other motors are a similar spec ,, 24v , 4.85 amp , 115 rpm , 2.71 nm and doesn't say anything about gearbox,,i've not got a clue what chair those are off,,,i can ask him when i see him though if you want.

Ya it wouldn't hurt to know the specs/model of the chair.


And wait a minute, since when cant a JRK drive 24v motors ? Isn't "Miltons CXC replica" wheel chair motor's 24v ?

Ok i'll ask him next time i see him,,,,,,,, cheers ,just checking miltons thread out now

heyuw

huh?

strongly later, the engines air quality.

Hi @stevemontuno looking at you pics of the motors you posted im pretty sure the 24 V dc 110 Rpm 3 Amps are almost the same as the ones im using in my 6DOF platform . ( still testing that is ) im tried using Levers with CTC 100 mm and considering I weight Ahemmm 100Kg and with the Platform upper section +seat weighing another 20Kg they threw me around Pretty well , tho only issue I came across was My gearboxes did back-drive so that was the only weakness I found , I also did the same test using 50mm CTC and this time the gearboxes held position and only the limited Movement from the reduced CTC was the issue

I would think that a balanced Seat mover taking all the load then they may well be within the capability of those motor/Gearboxes , just my 2 Cents worth ( but I'd not give up on those units just yet if I were you )
