eMotionButterflies

Ultralight flying objects with collective behaviour

Flying is a recurring theme in the Bionic Learning Network. The developers channelled their knowledge gained from the projects on the BionicOpter and the eMotionSpheres into the bionic butterflies. They combine the ultralight construction of artificial insects with coordinated flying behaviour in a collective.

Coordinated flying thanks to indoor GPS with infrared cameras

Ten cameras installed in the room record the butterflies using their infrared markers. The cameras transmit the position data to a central master computer, which coordinates the butterflies from outside. The intelligent networking system creates a guidance and monitoring system, which could be used in the networked factory of the future.

In order to replicate their natural role model as closely as possible, the artificial butterflies feature highly integrated on-board electronics. They are able to activate the wings individually with precision and thereby implement the fast movements. As the wings slightly overlap, an air gap is created between them when they beat, which gives the butterflies their special aerodynamics.

Consistent continuation: ultralight construction and collective behaviour combined

Networked overall system: the merging of the virtual and real world

Latest infrared technology: precise localisation of the butterflies

Unique flying behaviour: free moving like its natural role model

Minimum net weight: consistent lightweight construction due to low material use

Aerodynamic split wing: biggest possible wingspan with the smallest possible weight

Highly integrated research platforms with minimum use of materials

With the butterflies, Festo is taking another step into the areas of miniaturisation, lightweight construction and functional integration. The eMotionButterflies impress with an intelligently employed mechanical system and the smallest possible power units in the tightest space. The reduced use of materials enables the true-to-nature flying behaviour.
