Showroom DIY 2DOF MOTION RIG (WIP)

As of 5/22/24 we just finished the base frame without steering wheel or motor support yet.

We have tried it where someone sits on it and the other person moves the seat around and it feels super crazy. We are super happy to have made it this far with no major problems. We chose to go with a car seat because it was cheap and adjustable both distance from the pedals & steering wheel.

What follows is a super high level of the steps we took to get this:




Before anything we designed everything in SolidWorks to make sure our design was feasible of course.

First, we collected our steel: 20' 1.5" 14ga for our top frame, 24' 1.25" 14ga for our bottom frame, drive shaft from F-250 Super Duty for the universal joint, seat from a Lambo, various fasteners, and 2 steel purlin clips to connect the drive shaft to the bottom and top frame.


With our material, we then bought the cheapest angle grinder we could find $15 and cut all the steel and welded it together.



Welding the drive shaft after further cutting it down (sorry for bad photo quality):


Excuse the bad looking weld we stacked 4 beads and one of the passes was super quick.


We are still looking for motors and gear steppers (<$200 preferably if you have any suggestions), and I will add to this post next time we make significant progress on the build, should be around August or September of this year.

Right now I was eyeing some AmpFlow $49 motors on Amazon along with some $50 worm gear boxes ($19 on Alibaba, but extremely inconvenient to ship, I may place an order in now though). With these the Sabertooth 2x32 Driver with an Arduino.

good lookings welding is overrated ;D my joints look also terrible but they work and a good sander helps afterwards
