Avoiding objects



This is my first day here on LMR and I think it's a great site for learning new stuff for my robot.

Currently I'm working on my very first (own) robot.

What I have now is a cybot based platform (2 motors and a front wheel).

De motors are driven by a L298N driver.

That driver is connected to an Arduino board.

My next challenge is avoiding objects and I'm not quite sure what kind of sensors I would like to use.

First we have normal switches mounted on the front sides. (I rather not use this)

Then I thought of ultrasonic sensor, but for the moment I do not have the money to buy one (or at least 2).

Then I found the IR obstacle detection article of Oddbot and thought that's the way to follow.

But maybe there are other ways that I haven't found yet?

that’s pretty much thatyou

that’s pretty much that

you can also use a camera, but maybe later :smiley:


The only options I can think

The only options I can think of that haven’t already been mentioned are either quite complex (i.e. capacitive sensing) or expensive (i.e. laser ranging).

thx for the tips Can

thx for the tips


Can someone tell me (or give a good link) on how that detection of Oddbot exactly works?

I understand how ultrasonic works, but how does IR detection work?

IR doesn’t bounce back to the receiver, does it?

remember, whenever you see

remember, whenever you see anything, it’s actually light bouncing off that object and into your eye
