Well, at this post I will share my experience in creating a simulator drive with super low cost, I just need less than 2 million rupiah or 148 dollars in producing it. why is it cheap ????. It can be cheap because I use scrap or recycle. for more please read my tutorial
Step 1: Research & Design
Why do I put research and design in the first step instead of the item preparation? , because by prioritizing the mechanical design we can estimate what items we need to use, used for what simulator? plane? ship? or a car? in this tutorial i made a car simulator,
Design is very important in order to minimize errors and wasted items. although in its manufacture, I changed the design in mid step because it did not find the appropriate item. I use autodesk inventor 2013 to design it.
here is an example of my final drawing designl.
Step 2: Preparation Material
Look for examples on the internet to get imagination about the drive simulator. here I find a lot of different forms of drive simulator and think about the advantages and disadvantages. there's something I use and something I ignore.
Some items I use include iron hollow (used from the fence of the house, wiper motor (former motor car steering, U-joint coupling (former cardan truck, seat (former office chair, bolt and nut, power supply CPU supply, arduino mega + driver + potentiometer (new item) and the last is notebook.
the following picture where the material is installed
Step 3: Mechanical Manufacturing and Test Movement
In this step I make a drive simulator frame using hollow iron and U-joint cardan with welding, test movement using hand

Step 4: Actuators Manufacturing
In this step i make a transmission from the motor to the top frame drive simulator that moves using planar theory
Step 5: Movement Test With Simple Electronics
In this step i try whether the motor is strong enough to sustain my load by using a simple switch circuit with power supply

Step 6: Drive Simulator Test With Microcontroller
In this step i try to drive drive simulator using microcontroller. in this case I use motor actuator with continuous rotation, when should drive simulator move based on angle like servo motor. because of this problem i made wiper motor into servo motor using potentiometer as sensor and PID control as control.
In this microcontroller program I also have added the program to be able to directly control the frame frames over not just the motor angle. I use two planar kinematics theory to make it. you can see my video about this theory simulation using matlab in https://www.youtube.com/watch?v=hB0fC7h8zEM
in this test the result I can motorize according to the angle that I input it

Step 7: Integrate With Computere
In this step i tried to combine drive simulator with my friend's driving game which made with unity software
Step 8: Test Drive Simulator With Another Game
In this step I try to use live for speed (LFS) games and simtools that I got after joining www.xsimulator.net. I recommend this site for drive simulator research.
Some videos when I try with LFS

Step 9: Plan to Improve Drive Simulator
I should not display this because in this step only the design that I have not realized because I have no funds wkkwwk. maybe among friends there who can realize it, I will be very grateful.
Keep learning and trying friends
