Technology fluency
Problem solving; stepwise
Collaboration




Kinesenthetic 





















Swarm Robotics


Swarm Intelligence
Loose adoption to allow for programmability
Awesome research: ASEBA, ePuck

Why Swarm?
●	Parallelism
●	Robustness
●	Scalability
●	Heterogeneousness
●	Flexibility
●	Cheap Alternative

Ways to do Swarm Robotics





Event based swarm





Particle Photon
Small and powerful
Wi-Fi connected
Open-source HW & SW
Cloud services out of the box
Programmed in C++
particle.io

Device Setup







Programming Features






External Events

Shared between all Turtles and the mobile app
You can chat with robots:






Internal Events


Interrupts by sensors, fire on change.
Problem: ISR must be very short (in µs)
Solution: set up a timer.
Good side effect: debouncing.





Parallelism
When programming all devices
All code is executed in parallel, except when taking turns.

Positioning ( soon to be ready ) 
There are many local and global positioning techniques : 
GPS
Mobile Positioning Technology. 
WPS ( Wifi Positioning system ) :

Karam Shawish () - (Working on ) is it OK for you ?
Wifi Positioning System ( Distance Based ) 
ways to calculate the distance between the device and the access point : 

ToA ( Time of Arrival ) : 


RSSI ( Received signal strength indicator ) : 

RSSI(d) = -10 n log(d) – c ,  n : path loss exponent, c : environment constant
	





Wifi Positioning System ( Distance Based ) 







Also we can use Wifi fingerprint to Define a location

For more about this , see : schollz/find on githup









Constraints
Connectivity
Computational Power
Hardware Accuracy




Future Work
Enhancing app and Turtle UI and UX.
Translation to Arabic.
Adding iOS support.
Hardware upgrade.
In-app simulator
Fully implementing local positioning techniques.
Tutorials and challenges.
