1 Facons team update Presentation Portuga Workshop 2015

2 Contents ASML s mission for Robocup Software updates New vision system

3 Mission

4 Vision for Inside ASML there is a growing awareness for the Facons team, resuting in request to demonstrate the robots on job fairs and schoos The Turte 5k hardware is not used to its imit yet and winning mutipe games shoud be possibe with current hardware New hardware shoud be avaiabe before current hardware becomes the imit This resuts in: Creation of a new demo team with dedicated demo software Optimization of current hardware and software, e.g ba handing and shooter/kicker Writing and execution of test pans Start deveopment new hardware

5 Team constraints A work is done off-hours (evenings) with vounteers Team consists of approx. 34 vounteers Team ooks big, but is ony 5 FTEs

6 Upcoming activities Dutch open in March 2016 About 9 demo events in H Mini games against TU/e and VDL robot sports WM in Leipzig

7 Software updates

8 Phiosophies to program by 1/2 Share code with other teams KISS-principe Be future proof ROS interface and types decouping Behavior-driven deveopment Make use of continuous integration

9 Phiosophies to program by 2/2 Create software that is Scaabe Maintainabe Testabe Activey rework and refactor Document code with DoxyGen Maintain wiki pages

10 Genera technica notes what why status Migrated SVN to GIT Deveopment efficiency (branching) Done! Upgraded to Ubuntu 14 and Use atest and greatest packages ROS jade Done! Isoate SW interfaces (ROS, UDP) from interna ibrary Future proof; improved code re-usabiity Mosty done! Reduce SW atency Improved responsiveness In progress Repace python with C++ Improved performance / reduced CPU oad Mosty done! Rewritten firmware from scratch To sove China drunken robots ; code maintainabiity; adding new features Testing Panning to use Gazebo Repace custom with advanced out-of-thebox simuation; visuaization capabiities Not started

11 Overa architecture

12 Teampay (strategy/reasoning) Inspired by CAMBADA s strategy software architecture Teampay modue (node) decouped from ROS; therefore interchangeabe in future Added ayering to prevent code exposion Naming in ine with other teams Convert Teampay code from od (Hefei) to new (Leipzig)

13 Vision system

14 Vision system - Contents Turte5k vision Requirements Standard soution Do it yoursef Proof of concept Concusion The future

15 Turte 5k vision Fied 18x12 meters Camera radius about 4.5 meters Edge coor distortion from tube Edge coor distortion from mirror Ony down view Not abe to track obbing bas Inefficient use of pixes 16:9 to circe view Difficut to caibrate No homogeneous tangent function Optica/mechanica Difficut to determine distance

16 Down view

17 Increased view

18 Requirements 360x120 degrees 60 FPS Resoution 800x600 per camera Low atency ess then 5ms Synchronized (goba) shutter ess then 1ms Low optica distortion (< 80 degrees per camera) Tota size assemby (h<15cm, d<20cm) Communication Interface Linux / OpenCV compatibe Avaiabiity Affordabe (ess then 1000 per robot)

vertica view Cosed design Panone 360x360 36

expected in 2018 Sphericam 360x360 6 camera's

19 Standard soution Most of them are Large Expensive No streaming (SD card) Limited vertica view Cosed design Panone 360x camera's (45 degrees each) 1499, streaming expected in 2018 Sphericam 360x360 6 camera's (90 degrees each) 60 FPS Pre-order $1999, expected January 2016

20 Do it yoursef Standard x86-64 interface Genius Widecam F FPS 120 x 65 degrees 8 x 45 = 360 degrees (vertica) 8 x 40 Unknowns Bandwidth (USB 2.0) Latency Shutter contro 30 FPS Camera contro from Linux

21 Visibe area

22 Proof of concept Hardware 2x Genius Widecam F100 3x Logitech C525 3x Streams 4 x 3GHz Synchronization Each camera/stream in thread Use create join to synchronize

Resuts Success 5 camera's 800x600 30 FPS Camera contro

23 Resuts Success 5 camera's 800x FPS Camera contro Fai Maxima 1 camera per USB hub Synchronization error > 5ms

24 Synchronization fan test Shutter synchronization 250ms per turn 250*20/360 = 14ms Concusion Cosed design Dead end

25 The future Smart-phone camera soutions Raspberry Pi camera Ardocam added shutter contro Mutipe camera's to FPGA Stereoscopy
