Control Of Other Motors

Skip to comments   Jump To End

:Hi DJ I am new to the robotics field and have always wanted to try them out. I have a couple of questions while I am waiting for my "Goodies" to be deliverred.

  1. Can High Precisin "digital servos" be utilised by the EZ?

  2. Would the Motor Controllers "ESC's" that are used by electric aircraft models for the brushless motors work withe the EZ.

I have a number of servos, and ESC-Motor combos from my model helicopter exploits.

Seems that the motors would provide numerous different approaches to robot mobility.

How about hovercraft motion then setdown activity??

Just ramblin and spinning my mental wheels.

Thanks

Pistolero

Hey dude! Nice to meet you:)

For motors, you'll want to use an HBridge. Check the Add-Ons page and I have a little blurb about them. There are a few I recommend. Specifically a few cheap ones using the l298(?? I forget the chipset) that are on eBay. I find them for $4-5 assembled! Cheap cheap.

For specific high precision servos, you'll need to provide me with a model number and maybe even a datasheet. If they take regular servo signal, then yes. If not, then not right now. I have no problem writing some code to support them:) ...

Now, if you're making a hovercraft then SWEET!!! I would very much like to see that!

Thanks for the quick response DJ

The servos use the standard digital package so I guess will properly interface. They are alittle bit more current hungry.

I think you mis understood the motor controller question, the drive motors on electric helicopters are brushless and can draw high amperage 5-120 amps, they are controlled by an electronic speed controller which in turn is an output from the RC receiver. I believe this is an output that mimics the one needed for servo control. (basically they are AC motors)

I guess when my EZ setup arrives I will Get the chance to try it out, hopefully without a cloud of smoke.

Having a High power/high speed motor would be critical to this nagging "hover craft idea.

Thanks again for your work and interest.

Ah okay. The electric speed controller will take a servo signal also, I imagine? So that means you can use the Modified servo Movement Panel to adjus the speed:)

The VR's on the I/O are pretty powerful. They might not have any trouble with your servos. I can't think they would:)

Hi dj

thanks again for the quick response.

I am one of the old school "ALL ELECTRONICS ARE BUILT OF SMOKE --- LET THE SMOKE OUT AND ALL FUTURE INCANTATIONS ARE FUTILE.

THAT BEING SAID i THINK YOUR SYSTEM LOOKS FLAME AND SMOKE PROOF.

Will undoubtably be in touch again.

have a good day
