Movement tracking table-tennisball shooter

Hello robot building people :-)

 

After reading about peoples projects here on the site, me and my brother got intrested in building our own robots.

I'm studying (1st of 4 years) to become an electronics-technician myself, so i have some experience in working with electronics.

We already built the robot from the "How to make your own robot" tutorial.

The next thing we want to build is a bit more complex, and this is where we need some help from you guys.

 

We want to build a robot that shoots table-tennis balls at moving, human sized, objects :-)

For the tracking of the object, here are our thoughts:

The tube that shoots the table-tennis balls, will be moved up and down (Y-axis) by a servo-motor (using some gears or similiar)

The tube will be moved left and right (X-axis), also by a servo-motor.

 

So here comes the problem:

What kind of sensor do we use?

It must be able to guide those two servo-motors to their target (precision can be adjusted later on)

We want the table-tennisballs to be shot at the target, even if it stops its movement.

 

Also, we need some heavy duty servo-motors, specially the X-axis motor, that can move a few kilos of weight, and do that fast.

 

If you have any ideas for our project, or could help us get started, it would be much appreciated :-)

 

Best regards.

I agree with XicoMBD

If you want to track and/or identify objects a webcam/computer would be necessary…

I use MRL (myrobotlab) in my projects…

Good Luck.

Webcam

I would recommend you to use a webcam with a computer.

You may find here some inspiration: http://www.niklasroy.com/project/88/my-little-piece-of-privacy

It detects very well the X movement but you would need to improve the application to analyze the Y movement as well.

 

Anyway, good luck with your project :smiley:

Hello again, thanks for the

Hello again, thanks for the responses!

Nice projects both of you, it gave me some inspiration, and ideas to get started :slight_smile:

 

I will update in here when i get started on the project, and there will most likely come some questions up too :slight_smile:
