controll a motor using some kind of sensor

Hello

Have got an idea that I would need help with.
Want a motor to open a port for my robot lawnmower, but how will the engine feel when the door is to be opened / closed, thinking that i can mount some kind of sensor on the mower. So the motor opeans the port when its going out.
And when ist coming back to charge, it will open the port

mmm i found ultrasonic distance sensor that make work, using that and some kinde of motor, but how far can it see?
has 10,000 more questions, but hard to formulate, using google translation.

This is the third one of these in a week. Are you guys working together?
