2dof (plywood and aluminum profile construction)

Today the normal drivers came along with the motors. Everything works fine here. Many settings

First tests. Confused the direction of rotation and broke the clutch liner. The potentiometer is not damaged

No problem. 15 minutes and I have 5 more such inserts. The trials continue

I understand and edit the Arduino sketch for my motors. At the same time I made the hood of the car from 8mm plywood and printed the corners on a printer.

New addition to the design. Blower fan mount combined with speed or tachometer display

Preliminary wiring diagram version 1.1 according to the arduino code. The schematic and code will still be refined. I'll post the code to the latest version when all tests on the simulator pass. SimTools got DIY license for which many thanks

Reinforced the base with a transverse bar
Glued the LED strip

Reinforced with metal plates the hinge attachment point

So it was before


Set the button to the right of switching manual mode and operating mode from SimTools

This is what the backlight looks like

Case for arduino

There are two files in the archive for printing - cases and covers for arduino uno. Arduino is fixed with M3 screws.

The assembly continues! Fan, driver and motor are positioned to maximize airflow for all of these devices.

Ventiyaltor mount

Electrical installation is complete. Soon I will connect to a computer and test

First movements

first movements is such a great moment!
congratulations

is your plateforme balanced when you're seated? the pivot looks like it should be more in the front... not easy on picture

If you want a precise simulator you'll need to prevent the spring effect of the rig (shakes after a stop). It'd require more rigidity.

The center of gravity was found with a pipe. My weight is 80 kg. Rigidity on plywood is difficult to obtain. Can add some ribs

At 50% load, both motors were running, but the amplitude was small. At 100%, the engines did not run for long. The driver of one of them went to the defense. It turned out that one 500 W power supply is not enough for two motors (188 W) at full load. Works great with one motor. I will put another power supply unit. There seems to be no spring effect on the platform I have loaded. Here is a video for evaluation.

You may think to add a battery instead of a second PSU. It'll help to provide high surge of current and protect your PSU. It's a choice to consider IMO.

Yes, with this velocity at 50%, no spring effects! good
But I'm sure will crank up the juice and some brackets will help!

While I'm waiting for the power supply. I decided to take up the speedometer, tachometer and fans. In the figure, a left car mirror simulator, which will have a built-in LED strip for the speedometer and a fan for blowing. It will be the same on the other side, only there will be a tachometer
