From time to time, my kitchen falls victim to a bored dog. When left unattended, skirting boards, dog beds, kitchen towels, kitchen cabinets and paintwork have all suffered. To help keep my pupper entertained while I’m at work, I developed an IoT laser pet toy to keep him occupied. In the auto mode, a laser will move around the floor in a random pattern for a period of time, after which treats are dropped to reward the pet. The reward is important so they don’t get frustrated by the elusive laser and it encourages them to play!
It can be controlled manually via a smartphone, or set to auto mode. It can also be activated by voice using Google Assistant(auto mode only).
