I mentioned at the end of my tip/walkthrough on making IR obstacle detection sensors that they could be used for tracking an object and it would be great to track the cat with it and shoot it with a waterpistol. So now I'm posting it as a challenge. It's usually difficult to wash a pet anyway (not just cats) so lets make it fun!
Before anyone acusses me of animal cruelity, I like all animals (and some insects) but damn it is funny when a cat or dog is curiously investigating some new object and they get squirted for their trouble.
Make some sort of object tracking system using whatever sensors you have. Use it to aim a waterpistol at any object within a certain range. Video it tracking and squirting a curious pet. It must track the pet prior to and during the squirting to demonstrate your robots hunting ability. The funniest video wins. It may be a stationary system or a mobile pet squirter.
I used cat splat because it rymed but any pet can compete even if its not yours.
I've had to extend the the challenge to allow for seasonal differences (Petsicles will be disqualified).
This is SplatBot MkI. I built him to give anyone interested in this challenge some ideas and prove it can be done easily with a reasonably cheap pump. Admittedly MkI is a bit clumsy with all that weight on top and ended up straining the servo that raises and lowers the cannon. The MkII will have the waterbottle on the chassis and a better IR tracking system, something I still haven't perfected yet.
