Since I've been working from home I've had a small annoyance that really needed an over-engineered solution. I leave my office door cracked so that the dogs can push it open whenever they want to come in. The problem is that they can't make up their mind and constantly paw at the door to leave and then push it open again 2 min later.
This is Version 1 of my Door Bot. I currently have an Arduino with an IR receiver hooked up so I can use my TV remote to open and close the door for them from across the room.
I designed this around an MG995 servo and a geared DC motor I had laying around.
This is just a proof of concept and I'm already thinking about what I want from V2.
