Mel, do you have a link? Otherwise we have no idea which ones you are talking about...

#3  

I don't see how you could possibly use those for navigation... They are just a big proximity warning sensors and it doesn't look like they are directional, either... High Price and power consuming especially when you consider you can do the same thing with a ping (or PIR), 5V relay and ARC...

#4  

They just looked rugged and appealing. Thank you for the answer.

Rugged and appealing? Hey, that's what the ladies say about me! (I wish). :P

#8  

Very Interesting and reasonably priced.

This kind of sensor can read 360 degrees around a robot. In cars they sense a CHANGE in doppler effect of a microwave signal ping. If your robot is still maybe you could use it as sort of a motion detector for when someone walks by.

@moviemaker - this thread should not have been marked as requiring assistance. it doesn't have anything to do with EZ-Robot. It has nothing to do with asking for help. Tsk tsk

Hey, I don't mind DJ if you want to remove that credit from me.... I really didn't do anything but go to the eBay listing and read up on what the device was... @Moviemaker could have easily done the same thing and got his own answer...

sorry :-(

I always think in terms of robots and I always imagine that the EZB will be working with whatever I have. I have two arduinos collecting dust in the closet and about 4 or 5 Basic Stamps. I will NEVER go back to those obsolete processors.

Mel, I just read what the device can do.... you could have easily done the same thing....

Mel, I covered microwave sensors a week back I also talked about electromagnetic sensor (very interesting sensor) and (very low cost and accurate) 4 zone ultrasonic sensor arrays (vehicle parking sensor hack) which I use for navigation/obstacle detection. Check through the last pages of this thread.

Tony, I don't know how I missed that.
