Showroom 2 DOF - My first motion build.

A friend and I both decided to make our own DIY motion rig after finding this site.

We were going to go the arduino route at first for the cost benefits but later decided to go JRK.


At first I made a model so that I could get the software working, SimTools v1.3 at the time, and get my head around the basics. I have a video of this working but not on me. I will add it soon.


So we both started collecting the ingredients required to build our rigs and eventually about a month ago I had the below delivered.

My Kind friend had welded up a UJ to some plates, made some brackets and made some arms for the motors. He also sourced the motors.

The only thing I've done here is attach the rose joints.





Laying the main components out to see how they will fit into the space available.



The JRK's really are tiny



The bolts etc. have arrived so I start to put it all together. Using a part of an old Panasonic TV stand that my wife told me to throw away 5-10 years ago! I don't like throwing things away.



An unused panel from my new kitchen last year becomes the seat base.



Having missed a couple of stages of photo opportunity, here we have the motors bolted down and the arms attached to the seat base

I've never been very good at keeping my bench tidy while working.



"What do you mean I have to go to work? I'm busy" The next photo on my phone showing real life getting in the way




To be continued....

I'll be uploading more of the build later tonight hopefully then when the thread has caught up with real time my questions can start

Yeah I am already having some challenges but I will finish my project post before I get into that.

So the next day I continue my build


Mounting the pots





Both in place and working out where I'm going to put the JRK's before I find out I don't have the right size screws for them



Screws have arrived and with the use of some cut down raw plugs I secure them to the board.



All wires soldered or connected



Fan added.

Now it's time to take the old rig appart to make changes to it.

The obligitary BEFORE pic



Just for fun I decide to take pictures as I take it all apart, I won't bore you with all of them.











My wife was especially please with this photo



She was not so pleased when I started to put it all together again.

Time to rebuild


Outside to remove the old base and cut it down.



Back in position with the new increased height.



Pedals in. Time to start adding the rest back



It all looks so neat and tidy before the cables go back in

Again I forgot to take more pictures while putting it together but you get the idea

Very good, do you have how many pounds on those engines along with the chair?

too many pounds Joao.

I did however get it working with iRacing last night and it managed to shift my weight.

Now starts the never ending tweaking session.

My self already made it work, but when the obese here sit motionless do not walk, here in Brazil it is very difficult to have access to these engines, I found a wiper here more powerful than by the math of the account of the message, now is to wait to arrive to see In what gives. KKKKKKK

Which model and where did you buy it?

This model .

By the graphics, it can 25Nm at 30rpm using a lever of 2.5cm with 100kg on top of the axle, ie the 2 engines will hold about 200kg at 30rpm the speed is not the best but that's what I can have.

Takes a look at my thread.
