theboemio simple 2dof motion simulator with wiper motors

English version

Hello to all the community!

This is the second simulator that I built, I did not post the first one because my PC does not pass through customs on the way to my new home here in Mexico but, I promise to publish it as soon as the recovery. 8)

My hardware:

PC:
965 x4 Phenom 3.4 GHz
4 Gb Ddr Ram Ghz March 1333
Monster Power 800w
Nvidia GeForce GTS250
Gigabyte Ga-M68m-S2 Socket Am3

Parts and accessories
Toyota Corolla Seat
Logitech g25 with some modifications made by me
LG Full HD Display 42
Analog handbrake
E-Dimencional glasses

Motion control:
85 w 2 wiper motors
Dual Motor Driver Carrier MD03A VNH2SP30
Pololu Micro Serial Servo Controller
4 Power HD Micro Servo HD-1800A
Monster Power 800w atx










I've used a single PC for both the game to control.

Here is the simple diagram:



Works simple, the X-SIM software is compatible with RS-232 interface, then connect the servo controller through the serial port and servos to this and should move with the correct configuration in PROFILER. Disarmed after the servos to extract the PMW signals that will be amplified by the motor controller VNH2SP30 and sent to the wiper motor, and just stay attach the pots to the motors.

I've used a 800w ATX power supply, 80A on the 12V output according to the brochures and I made some internal changes, including:

* Cancel the protection against over voltage.
* Raise the tension of 12v to 14v.
* regulated the output of 14 volts.

Typically these sources only regulate the 5v voltage by the error amplifier within the IC then, we must send the same intention but since the ouput of 12v, so when the voltage drop will increase the output IC to replace the voltage drop, We do this with a pot and turn the shaft to get about 14 or 13 volts regulated.

In this source power vast with remove the leg of the IC shoot protection according to its data-sheet number 4

This will be different for each power supply according to its inner workings.

As for the simulation of the wind, it creates another axis with the values of the wind and used the output of the other servo PMW placing the pot in a stable position and taking advantage of the margin of error for controlling the fans. A very inusuable to do but gives very good results.

Although I have no video with fans and other accessories as soon as I get the camera can be sharing here in this thread.

Hola a toda la comunidad!

Este es el segundo simulador que he construido, no pude publicar el primero por que mi PC no paso por aduana de camino a mi nueva casa aqui en Mexico pero, prometo publicarlo en cuanto la recupere.

My hardware:

PC:
Phenom x4 965 3.4 Ghz
4 Gb Ram Ddr 3 1333 Ghz
Fuente Monster 800w
Nvidia Geforce Gts250
Gigabyte Ga-M68m-S2 Socket Am3

Partes y accesorios:
Asiento toyota corolla
Logitech g25 con algunas modificaciones hechas por mi
Pantalla LG full HD 42
Freno de mano analogico
E-Dimencional gafas

Motion control:
2 wiper motors 85 w
Dual VNH2SP30 Motor Driver Carrier MD03A
Pololu Micro Serial Servo Controller
4 Power HD Micro Servo HD-1800A
Fuente Monster 800w atx










Yo he utilizado una sola PC tanto para el juego como para el control.

Aqui esta el diagrama muy simple:



Funciona simple, el software X-SIM is compatible con la interfas de rs-232, entonces conecto la controladora de servos por el puerto serial y los servos a esta y deberian moverse con la configuracion correcta en el PROFILER. Despues desarmo los servos para extraer las señales PMW que seran amplificadas por la controladora de motore VNH2SP30 y enviadas a los wiper motor, ya solo quedara acoplar los pots a los motors.

Yo he utilizado una fuente atx de 800w, 80A en la salida de 12v segun los folletos y le hecho algunas modificaciones internas, como:

*Anular la proteccion contra sobre-tensiones.
*Elevar la tension de 12v a 14v.
*Regular la salida de 14 volts.

Normalmente estas fuentes solo regulan la tension de 5v mediante un amplificador de error dentro del CI entonces, hay que hacer llegar la misma tencion pero desde la salida de 12v, asi cuando caiga el voltaje el CI aumentara la salida para reponer la caida de voltaje, esto lo hacemos con un pot y lo giramos asta obtener unos 14 o 13 volts regulados.

En esta fuente vasto con remover la pata del CI que dispara la proteccion segun su data-sheet la numero 4

Esto sera diferente para cada fuente de poder de acuerdo a su funcionamiento interno.

En cuanto a la simulacion del viento, se crea otro eje con los valores del viento y se usa la salida PMW del otro servo situando el pot en una posicion estable y aprovechando el margen de error para controlar los ventiladores. Una manera muy inusuable de hacerlo pero da muy buenos resultados.

Aqui un video:

Aun no tengo un video con los ventiladores y los demas accesorios, en cuanto me llegue la camara los estare compartiendo aqui en este hilo.

Nice build! Congrats!

I would perhaps restrict the sideways movements a little.

Regards

Nice one :thbup:
And in your next video try not to sing so loud :lol: :lol:

LOL, the Hifi playing the soundtrack broke in the background. He had to do something about it!

Good job! But where do you take the feedback for positioning? And how does that board convert RC signals to PWM?

I saw the pots in one of his pics. Looks like regular motor shaft mounting, so ...

disassemble the servo motors, I replaced the original Pots for a few pots of equal value and connect the outputs of small motor to pins INA and INB of Pololu motor controller for feeding direction of the motors and pull them into the input pin PMW with diodes to prevent a short circuit, so only receive the PWM signals. :hi:

:lol: :thbup:

So you are using the circuit from RC servos for position control... That is very smart! I never thought about that.

Well done another pololu sim hits the tracks tried this myself but could get them to work nice but i see now what i did wrong. Jrk12v12s ended up working for me.

Well done for thinking out of the square.

The in-game steering wheel doesn't match the G25. Is there a reason for that?

The game Need For Speed Shift does not simulate the 900 º of rotation that has the g25 only turns about 200 degrees, it would be necessary to change the configuration of g25 to 200 º.

In games like LFS can simulate the 900 ° swivel and looks great. :
