Keith's 2dof rig

Yes that is a very clean looking sim. Im actually chopping my drive shaft down by 6 inches to bring it down a bit. Next im going to build the bottom frame for traction loss. I might go through a couple prototypes for this.

I made a bit of progress on the frame. Im not real happy with the wheels and how they are mounted but I just need to move on. Let me know if I made any mistakes or if you have a clever idea for me. Thanks!

Updated on my new frame.

Great job. I will send you my wheel ideas later on. To stabilise the rig you should have 2 wheels at the front

Ok that sounds great thanks!

I made some more progress last night. Here's a pic

what seat do you use? is it comfortable?
I have a bucket seat (SPARCO) and its great only for short period.

BTW. with the speakers you have you probably don't need the rig at all. Just play the game loud and you will feel every move

The seat is out of a Pontiac grand prix. Its pretty comfy. Its a power adjustable seat which is cool but the downside is weight. (80 lbs)

Lol pretty much. I have young kids now so I dont get a chance to really crank them up very often.

Hey guys. is there a way to adjust the baseline or the level point of my rig. I physically adjusted the levers and pots downward to avoid the rig from starting the motors up in reverse. now I just want to adjust the level point in the software if that makes sense. Im not sure If I have to reprogram the arduino or make adjustments to simtools. Thanks

Thanks for the reply! In that picture the motors have fired up backwards. When the motor spins the correct direction it is at 90 degrees. Basically once I power down the rig it falls down and the motors will fire up in the wrong direction unless I prop up the cockpit. I think I might just replace the gt2 pulleys on the pots with bigger ones so it will have more than 180 degrees of rotation and cant start in the wrong direction.

The first pic is where it rests while powered up correctly. Second pick is powered down. In the second pick you can see the lever swings beyond strait down. That is what is giving me the issue of starting up backwards

Hey guys. I am struggling to get my traction loss working. The movement works in SMC3 utility but does not work in simtools. The baud rate is set to 115200 and I shorted #8 to ground on the arduino uno. Here are a couple pics of simtools

I figured it out.

Hi

May you can explain your traction loss system? I have understand the prototype but after you finalize the third motor is no more at the back it is in front of the level.

As well if you can, explain how you find out the height of your ujoint.

I am try to make a similar rig like you and use the same motors. I want to make prototype (try and error) and then make it beauty.

Yes that's the way to do it. The ujoint should be located as close to the top platform as possible. And you just want it placed somewhere so that the top platform is somewhat balanced(with a person seated) I have mine balanced to have extra weight on the front of the rig. This helped to hide the motor lash.

I will take some pictures of the traction loss tonight

Here are some pics of the traction loss. Sorry it's hard to get a good pic of it.

And a quick video

hi. i also have the same motor as you and have 1 question, will the motor be pushed down when there is no power supply?
