This is awesome! A load of work you've put into it, very impressive.
I've been playing around with various hacks in rPi and Arduino, speech recognition (Mycroft - none of that big brother tracking for me), etc.
I might do something similar and perhaps go for an R2D2 flavoured robot for the height flexibility. Thanks for getting me thinking about it all again.
Hello. The measurements of the structure aren't fixed. They're dependent on the lengths of the flinging arm (in my case the dog ball thrower) and the spring (thickness, length, strength).
Hi Peter, thanks very much!
Good question. She'll definitely try to get at ANY available food. I chose the pvc, partly, so she couldn't see any food - it was 'miraculously being thrown from this machine' (dog's thoughts).
Additionally, I don't leave it sitting with food in it where she can get at it. She is only near it when it's operating and flinging food. Which generally keeps her excited and busy.
Naturally, she's sniffed and licked it. But I never fill it up enough so that she can see the dog biscuits in the pipe. So she can sniff and lick all she likes, but no food.
I also agree with you, she's a little afraid of the motor noise and movement. Luckily ;)
