I'm an automation engineer, prior to that I was an industrial electrician, pipefitter and welder. I can make one but virtually all the parts, which are readily available, have to be retrofit whether you use a drill motor, drapery motor or whatever. Things made in volume can be engineered for the purpose mass produced and bolt or snap together by $2 per hour assemblers.
I am in serious need of auto doors but haven't made one yet because I need 7 of them - 5 of which could be operated by a single motor. My time would be better spent designing something I can use for all the buildings yet controlled from a single location rather than custom make each door.
Why not use one motor and a series of pulleys with an electric motor on a timer. Each door gets a cable and you have a 5 "slot" pulley on the motor.
