1. Design of Engineering Systems II December 5, 2014 I.S.E. Design Project Group 1 Z. Abraham M. Desai J. Holloway M. Lim R. Schultz Fully Automated Soccer Trainer (FAST)

2. Design of Engineering Systems II December 5, 2014 I.S.E. Design Project Outline • Objective • Existing Machines & Motivation • Uniqueness • System Design • System Operation – User Interface – Drive System – Identifying Machine and Player Positions – Picking Shot Locations – Calculating Trajectory – Positioning System – Feeding System – Firing System

3. Design of Engineering Systems II December 5, 2014 I.S.E. Design Project Objective Design and build a fully automated soccer trainer for individual use that delivers soccer balls to various locations at different angles and speeds. The soccer trainer must be controllable from a smartphone app.

4. Design of Engineering Systems II December 5, 2014 I.S.E. Design Project Existing Machines & Motivation JUGS Sports Soccer Machine Pro Trainer Soccer Tutor SideKick Soccer Machine Globus EuroGoal 1500 • Difficult to practice alone • No product on the market today is fully automated

5. Design of Engineering Systems II December 5, 2014 I.S.E. Design Project Uniqueness • Positions itself automatically – Adjusts launch angles – Drives itself to shooting positions • Randomly generates trajectories and executes shots • Reads player behavior by using a camera • Controllable from a smartphone application

7. Design of Engineering Systems II December 5, 2014 I.S.E. Design Project Choose settings from GUI Machine drives into position Camera determines player preparedness Software picks random shot location Trajectory software decides machine’s internal settings Controller positions the machine Feeder releases ball Firing discs launch ball System Operation

9. Design of Engineering Systems II December 5, 2014 I.S.E. Design Project User Interface • Select modes and difficulty • Display soccer field to select where machine will move • Display goal to select shot location

11. Design of Engineering Systems II December 5, 2014 I.S.E. Design Project Drive System • Motion – One motor per powered wheel to drive the machine – Four-wheel structure • Turning – Spin one motor faster than the other to turn – Free-rotating wheel in the front for support Powered wheels Free-rotating wheels

14. Design of Engineering Systems II December 5, 2014 I.S.E. Design Project Identifying Machine Position • Finds location of machine on field by using the camera’s field of view to find the distance to the goal 50 100 150 200 250 300 350 400 450 50 100 150 200 250 300

15. Design of Engineering Systems II December 5, 2014 I.S.E. Design Project Identifying Player Behavior • Identifies player is prepared • Figures out player position in goal

17. Design of Engineering Systems II December 5, 2014 I.S.E. Design Project Picking Shot Locations • Generate random locations, angles, speeds and shooting positions • Machine learning to adjust random number distributions to “keep up’” with the user

19. Design of Engineering Systems II December 5, 2014 I.S.E. Design Project Calculating Trajectory • Inputs – Machine location on field – Desired shot location • Outputs – Motor positions – Motor speeds • Uses basic kinematics and spin equation based on Magnus effect

21. Design of Engineering Systems II December 5, 2014 I.S.E. Design Project Positioning System Launch angle adjustment – Adjusts horizontal angle up to 360º – Adjusts vertical angle

23. Design of Engineering Systems II December 5, 2014 I.S.E. Design Project Feeding System Ball feeding – Holds up to six balls – Motor rotates the feeder – Plunger pushes balls into the launch system

24. Design of Engineering Systems II December 5, 2014 I.S.E. Design Project

26. Design of Engineering Systems II December 5, 2014 I.S.E. Design Project Firing System Ball launching – Discs run by motors – Servo motor adjusts vertical angle

27. Design of Engineering Systems II December 5, 2014 I.S.E. Design Project Conclusion The Fully Automated Soccer Trainer (FAST) features self positioning, computer vision, and machine learning and is developed for individual soccer training.
