Here is an indoor inspection drone that can fit through manholes and go places where regular drones can’t. The Elios 2 drone comes with a 12MP camera and livestreaming capability. It has a spherical cage protecting its propellers from impacts. Elios 2 can capture close-up images in GPS-denied environments.
Elios 2 uses a thermal and 4K camera for close-up inspection. It also has a bright 10,000-lumen lighting system. The above video shows it in action.
