Robotic Cat Toy made with unused stuff I already had.
The prinipal feature ise the pan/tilt motorised laser pointer bracket. You can also connect a cat toy at the behind the bot. The head and the cat toy bracket are easily removables thanks to the slides. This bot is easy to program thanks to the accessible Arduino USB connector behind the bot.
For the surface painting, I used the marbling technique: Car body spray mastic (Soloplast) Surface sanding White acrylic spray painting Marbling (I used the EasyMarble Kit) Spray coating
