I've worked from home for about 14 years, and my software has worked from home for at least a decade. We work well "together" and have been successful. The remote work place has some challenges, but we've adapted. When offering remote support to customers we all are better at it and have a good idea what can be understood and how to go about the work.
One of the big advantages is having the space needed to really think free from distractions of coworkers. I'm definitely more productive.
If your employees won't work unless they are watched you have a management problem not a worker problem. Your employees obviously don't feel the success of the company is to their own advantage. They obviously don't feel like your giving them enough, and I don't necessarily mean money. Does the job make them feel important? Do they feel like they are contributors? Are you as a manager undermining the good they have done?
The idea that you could send one of these drones in a sensitive environment and leave it there seems off. Yeah, the air frame biodegrades, but not the motors, electronics, and the most toxic part the battery.
