Pet Robot Ball

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.

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.

For this project you will need:

17cm diameter Hamster Ball (https://www.amazon.co.uk/gp/product/B001B5DPB4/ref=as_li_tl?ie=UTF8&camp=1634&creative=6738&creativeASIN=B001B5DPB4&linkCode=as2&tag=cabuu-21&linkId=24782b2643cb8cd86e2358c13c0d9bb6)
