PC Based robot control code

Are you using the parallel interface to talk to the motors?

Eljin

Right now I am using a Velleman K8000 I/O board which talks on a parallel port I2C bus.

The motor amplifyer accepts +- 5Volts negative voltage go faster backwards and positive voltage goes faster forward. I am using two of the velleman D/A converters to drive the motors.

Why not just hook it up to the printer port?

So, you're producing the PWM/PID on the computer or is that what the PWM board is about? If so, you are just sending it commands?

Eljin

That's how the K8000 board works.

The motor amplifier accepts, as I said, +- 5V for control, it produces direction and PWM for the H-Bridge

I was looking at your web site again and I just realized that you are using the same drive motors as I am. Did you get yours from the Barbie Jeep too? :-)

What motor amps are you using?

Eljin

No, mine came off a BJs Wholesale "Scrambler." $65. I've seen it for as low as $35.

My own.

I like your encoder mount.

can you please give more detailed pictures, and perhaps more information?

How do you mount the encoder to the metal bracket?

Rich

Thanks.

Not without taking it apart again :(

With the single tool that rivals duct tape for usefullness: JB Weld epoxy.

Good stuff -- I've used it to make wheel shaft mounts for fairly heavy robots and have yet to see it fail, even under a fair amount of torque. It's amazing how well (and how long) this stuff holds up when properly applied.
