Sharp IR On Car Robot, Table Top Robot Avoids Falling Off
anyone know how to write this code in java?
:loop adc_wait(adc0,lower,160) stop() reverse(200,500) sleep(50) left(255,500) stop() forward() sleep(50) goto(loop)
now it starts, avoids falling off table, turns left, keeps going - cheers! All figured out below, I solved it below with help of thetechguru
thanks

From what I read,
the Sharp IR Analog Distance Sensor (6.99_ detects (avoids) objects in front of the robot, I have this, works well,
I going to try The Sharp Proximity Distance Sensor (9.98) to detect more of a depth proximity
I will receive this Sunday and test and let you know,
I think the distance sensors don’t work well with close objects, specifically edge detection.
the proximity detector is designed for close contact and edge detection.
proteusy,
received the Sharp proximity sensor, did the test,
much better results, responds very different
What is the reference of those sensores? Can you post a pic? Thanks
The ones I’ve used require a two resistors and they’re tiny and super cheap. Look like this
but you can get ones that have a pcb with the wiring all ready for you. Maybe like this from Amazon
Oh yes, i know those sensors. Thanks.

This is the Sharp proximity sensor, not the distance sensor
works well for me
Here are 2 pics:
In my experience, the sensor that ezang just posted isn't great for edge detection. They have difficulty with close objects and prefer a distance of 10+ cm away.
