Hacking and controlling toy flyers Mid-term presentation Student : Frédéric Blanc Assistant : Rico Möckel Professor : Auke Jan Ijspeert

Motivations Personal motivations  Electronic, mechanic and programming project  PCB design  Working on Flapping flyer Global motivation  Hacking vs designing complete flyers 2

Outline Flyer’s description Possible improvement Mechanical constraints Global schematic Future works 3

Flyer’s description 4 Two degrees of freedom: Yaw controlThrust control

Possible improvement Increase the number of DOF  Additional propeller for pitch control 5

Possible improvement Extend time of flight  Additional battery Stabilisation (Hovering)  New sensors (accelerometers, gyroscope, magnetometer) Complete autonomous control  Out of the field of this project but still possible with a camera and optic flow algorithms 6

Mechanical constraints Air vehicles implies light embodiment  Total weight of the original dragonfly : 22 g Light embodiment implies small PCB  Limited in the choice of components 7
