automated tennis ball collector

qiwenfarmer

hi, I am designing an automated tennis ball picker.

I already have stepper motors, drivers, and stepper motor controllers. And the collecting system is already built.

However, in order to make the robot to run most efficiently, I wanted to find the coordiates of each tennis ball laying on the court and figure out a shortest path. My proposed plan is to hang a camera on top of the court, take an aerial image. Then I send the image back to the computer program, then let program analyze the image and figure out each ball's coordinate relative to a pre-determined origin. Change the stepper motor pulses and send the data to the stepper motor controller and change its direction.

My question is how can I send the image back to the computer program wirelessly, and then send the stepper motor pulses to the controller wirelessly. I already have a BS2 with bluetooth. But do I need two of them for both wireless communications.

Also, if anyone has similar experience of dealing with similar problems in the past, please feel free to make suggestions. I don't know exactly where I should post the question.

Thank you

You need a wireless camera and a capture card in the computer or a wireless web or network camera. The signals to the stamp can be wireless bluetooth.

Take a look at RoboRealm. It's a free software program for a camera interface to a computer or robot. I've played with it a bit and have been very impressed with it. It's got a great set of filters and even has a sample program to use a BoeBot to chase a green ball.
