Practical use of drones in everyday life
Nemanja Stefanović
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
6 biilion $
2015
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?
