In this demo, there are seven Eye-bots searching a building for a desired object. The stationary Eye-bots are used as 3D reference points to guide the 3D path of the Flying Eye-bot. One Eye-bot is deployed at a time to search the building. Once each Eye-bot reaches the limit of its 3D sensor range, it attaches to the ceiling. Each Eye-bot does the same to extend the search chain further into the unknown environment. The search continues until the object has been found using their on-board camera (in this case a book on the shelf). The Eye-bots then communicate back down the chain to stop more Eye-bots being deployed.
The system relies solely on an on-board infrared 3D relative positioning sensor (the ring around the bottom) to determine its position in 3D space, with respect to other Eye-bots. It is also capable of proximity sensing in order to avoid obstacles (e.g walls, people) up to a few meters away.
