Arduino and stepper motor simple task

Hello. we are looking to prove a proof of concept. We want to open and close a door with a stepper motor and a Arduino.

The idea is tha we need to have the door to be safe. How can we make the steper motor to stop if some one puts their hand between the door and the frame?

we cannot use IR sensor or anything on the frame of the door. I was wondering if somehow we can read when the motor is beeing forced and use that to stop the door.

If you suggest using another motor or method we are open to suggestions.

So basically this job is as follows.

We need to decide which components to use, then we need to open a door the size of a show box and make the door detect if there is an obstacle. if the obstacle is there, the door will open.

Remember we cant use sensors on the frame of the door and we need to make it as simple as possible.

here is the door we will be opening and closing. the stepper is attached to the door axle, so the motor will move the door from the pivot of the hinge.

motor we plan on using.
