Introducing The Altair Ez:2 Robot

I have not actually used the sensor I'm about to mention here but car alarms often use a three wire device referred to as a " microwave sensor" or sometimes shock sensor. The detect movement 360 degrees through the windows . Maybe one of those modules can be used to sense the proximity of a person or animal to the robot... like the sixth sense that makes you paranoid when someone stairs at you .

@tony totally not trying to hijack you thread , I just figured you could weight you opinion in in the general use of a microwave proximity sensor.

Tony, There is alot of interest in your ideas and inventions. Sure like the Teach pendant. Altair EZ 2 is something I think is so advanced. Thanks for sharing, Steve S

Thanks @toymaker

This will be something I will definitely look at adding to a future project.

Keep up the great work

:-)

Thanks for the kind words guys!

Josh, microwave are great sensors, if fact in the nineties when I was a design engineer for one of the largest vehicle security companies in Europe, I was on the team that designed one of the first vehicle microwave sensors. In those days we used a Gunn diode en.wikipedia.org/wiki/Gunn_diode

With a dual zone sensor you will get 2 sense (distance) zones, here is a typical unit

Microwave sensors (like the electromagnetic sensor) are sensitive to movement of mass, so will not detect stationary objects unless the sensor is moving itself (on the robot).

The electromagnet sensor that I use is a bit more accurate and gives you 3 or more sense zones

Tony, Just checking for any updates. I luv the look of the EZ Altair robot. Steve S

@Tony, Your creation is beautiful.

But, I want to know why did everyone laugh at me when I suggested using a car microwave detector. ? It seems to work.

I am confused.

Steve, work is progressing with the EZ:1 and EZ:2 robots, I am just developed an "emotion" chip that will be very useful in human interactions. The chip is currently going in the EZ:1 (development) robot which has a whole new head and also now has 3 interlinked PIC microcontrollers. The EZ:1 is now being converted over to the V4. Thanks for your interest, I will post videos when the work is completed.

Mel, I do not know why people laughed at you about the microwave sensor as they could be quite useful on a robot. They cannot really be used for ranging like ultrasonics of IR allso they only detect movement and not passive objects, but as (moving) human/animal proximity detector they should work quite well.

Tony

Mel, you said you wanted to use them for navigation when you asked about them. You were told that they couldn't be used for navigation which is correct to a degree, it would need more. I am sure all of this was explained, in fact I am sure Tony referred you to this topic.
