Motor Load Detection

 
#1

Hey DJ,

At this stream at about 13:15 you said you had the motors plugged into the ADC port for load detection,

How exactly did you do it? I would like to know for my omnibot Grin

#2

Dj?

#3

Ditto I also would like to know specific how to on that. Also if I can choose what amperage is considered stalling because I'm sure with my bot weighing in nearly 20 pounds heavier I'm sure it will draw more.

#4

Anyone?

#5

Humm ? I can't get that one to play so I can't watch it .

@ww321q

At some point he just says omni's got motor load detection so if the load gets too high, he backs up.

#7

I think that's important to have as the ultrasonic sensor will miss objects that are to high or low to reflect the sound back . J.W. Smile

Hmmm interesteing concept

The way i would consider trying it would be to use an amp meter hooked to a sencer of some kind i think i have hurd of sencer diodes that respond to current flow if there is nothing like that i would try running the motors power lead though like rap the wire with another and monitor the power change in the coil it may not be a big change and probly vary little powor in the coil but there would be some and it should change as the motor draws more

in theary
in my head
dont know if it would work as i have not played with that stuff yet but i feel it would work lol

It works we have seen dj and other members do it , just couldn't remember where the how to tutorial was.

Take a look at this thread I think it's what you are looking for. I tried briefly but didn't work for me so now I use a Hall Effect sensor which does work when roaming autonomously
