Pet Robot Ball

thingiverse

My pet dog loves playing with toys especially ones he can chase! I built a robotic ball that switches on and rolls away whenever he interacts with it, notifies me via my mobile phone where I can then take over control and finally powers down when the fun is over to save battery. https://www.youtube.com/watch?v=YORRBN_0tdM The ball uses a d1 mini micro-controller, programmed using Arduino and is put together using some 3D-printed parts and some cheap, readily available components.
