Practical use of drones in everyday life

Drones vs. Robots

Tesla first patented remote control - Teleautomation

Robot - term coined by Karel Čapek in 1921

Unimate - first industrial robot in 1954

Ryan Firebee - one of the first drones created in 1951

MQ-1 Predator - development started in the 1980s

 

"Drone is an unmanned robot that travels through air or water"

Fixed wing - MTIS Pegaz 011,Predator, Reaper, Global Hawk etc.

Rotary wing - Kamov Ka-175, SAAB Skeldar etc.

Multi rotor - Lockheed Indago, Draganflyer, DJI S600, MultiWii etc.

Types of drones

Military vs. civilian drones

Military drones dominated the airspace in the 20th century

Expensive & complicated technology were to blame

More and more civilian drones exist nowadays

DIY geeks and affordable electronics are paving the way for civilian drones in the 21th century

Mutltirotor drones is the way to go!

This talk will focus on multirotor drones...

  • Simple operation, low maintenance & small size
  • They are the most affordable on the market
  • Multirotor = Multi purpose

So, how do they work?!

Multirotor elements

Few elements:

  • Motors
  • Flight control board (FCB)
  • Motor controllers (ESC)
  • Batteries
  • Propellers 

FCB - flight control board

  • "Brain" of the drone craft
  • Gathers & processes I/O signals, and sends controls to the motors
  • Various input sources - radio, GPS, altimeter, accelerometer etc.
  • Usually based on ARM 32bit chips.
  • Proved to be reliable & cheap

Bateries

  • LiPo - Lithium Polymer
  • Can sustain high loads
  • The main bottleneck for further drone development
  • Flight times ~ 15-20min

Motors

  • Brushless AC motors (Thanks Tesla!)
  • High RPM
  • CHEAP!
  • High endurance

ESC - Electronic Speed Control

  • Transfroms DC to AC for the motors
  • Controls the RPM of the motors by a PWM signal recived from the FCB
  • SimonK - custom firmware designed for multirotors

Multirotor flight mechanics

3 axis of movement:

  • Pitch
  • Yaw
  • Roll

 

Movement is adjusted by changing the RPM of the motors

Multirotor uses

Any ideas???

  • Delivery drones - buzz word

DHL, Amazon etc.

  • Search & rescue drones
  • Medi drones
  • Mapping & GIS
  • Damage control - Firefighters, Police etc.
  • Videography drones

Market Size

Legislation & Laws

  • More and more countries introduce laws for drones
  • Some laws are more restrictive than others
  • Some forms of control are necessary
  • Potential problems & dangers?
  • Sabotage, terrorism, illegal survailence
  • PRIVACY?

Thank you!
