2

Motivations

• Personal motivations

Electronic, mechanic and programming project

PCB design

Working on Flapping flyer

• Global motivation

Hacking vs designing complete flyers

3

Outline

• Flyer’s description

• Possible improvement

• Mechanical constraints

• Global schematic

• Future works

4

Flyer’s description

Two degrees of freedom:

Yaw control Thrust control

5

Possible improvement

• Increase the number of DOFAdditional propeller for pitch control

6

Possible improvement

• Extend time of flightAdditional battery

• Stabilisation (Hovering)New sensors (accelerometers, gyroscope, magnetometer)

• Complete autonomous controlOut of the field of this project but still possible with a

camera and optic flow algorithms

7

Mechanical constraints

• Air vehicles implies light embodimentTotal weight of the original dragonfly : 22 g

• Light embodiment implies small PCB Limited in the choice of components
