Hi Friends!. well I'm finally ready to put my full size R2 to roll... But I need a tip from you. What kind of H-Bridge or controller do I need (or can I use) to use with my ez-b ? I believe that the regular one will not be able to power this Scooter motors that i'm using.. am I wrong ?!

I see... But the Ez-b can read that the same way it reads the pot... But, well, I understand that once tuned, the kangaroo will allow me to command the motor to any position.. Almost like a servo ... I'll try to see what happens.
EZB can not read an encoder. That's why you need a motor controller like the Kangaroo that will read the pulses sent by the encoder and control the Sabertooth.
EZB can read a pot because a pot measures the differences in voltage from one side of the rotation to the other. A common encoder sends out a puses as it reads and counts light passing through holes in a wheel as it turns. EZB can't accept though puse readings.
You can use either a pot or an encoder with the Kangaroo.
friends.. here I am again asking for your help! ok, I got the sabertooth (2x12) I got the Kangaroo, and, instead of an encoder, I got a POT - the blue one, with 10 turns..
I figure out how to connect everything. it's not that hard. but I'm stuck again at the script point. Where do I go now ? How to control it from ARC ?
help please!
Thanks
Success! Friends,after a painfull learning process, I have finally get my system with the sabertooth and kangaroo to work properly!
Well, after lots of frustrating attempts to set up using a pot, I decide to buy some motors with encoders. Then I found out that my Sabertooh board was defective.
One of it's channels was not working. I got in touch with Dimmension folks and they were very helpfull ! After a lot of configuration guided try outs, we saw the sabertooth BURN to death!.. then, DImmension Engenering sent me another one, FOR FREE!.
And, this one is working great! I simply connected the motors and encoders, did the tune on both motors, and... THAt's it. It worked with servo COMMAND in ARC. So, my conclusion is that my board was broken at first, an here Is my thanks to Dimmension for the perfect support.
Someone should make a User Tutorial in the learn section on how to setup a kangaroo + sabertooth to work with servo Command in ARC. hint hint
I will do it! ??
Just did it.
Bom trabalho tevans, bom tutorial.
