I have a thin wire, hanging from a hovering quadcopter drone. I'd like to detect physical contact of the wire with a base station. What's an appropriate sensing mechanism for this?
The thin wire does not need to be insulated. It is about 20cm long. We can assume the wire is quite straight and hanging straight down from the drone. The base station is a disk of about 20cm in diameter. The disk is parallel to the ground. The drone will approach the disk from the side in a horizontal motion such that the write hanging below it will contact the edge of the disk. When this happens, I'd like the base station to detect that contact has been made. The drone and the attached wire are not grounded. Hope this is a bit clearer of what I'm trying to do.
