How it would work?
The security and cleaning firm Taisei and the Telecom Giant NTT have developed this system for the offices. The drones will be patrolled on a path already scheduled for them. These drones would also be able to record video footage during the flight. So, all those who remain in the office even after closing time would have to cope with the Auld Lang Syne, which will be played to make them realize they need to go now.
Pricing:
The system will be out in the market in April 2018. As far as the fee of this drone system is concerned, the company is targeting to charge ¥50,000 ($450).
