Fully Automated Soccer Trainer (FAST)



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



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.



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



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

System Operation



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

Identifying Machine Position• Finds location of machine on

field by using the camera’s field of view to find the distance to the goal

Picking Shot Locations• Generate random

locations, angles, speeds and shooting positions

• Machine learning to adjust random number distributions to “keep up’” with the user

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

Positioning System

Launch angle adjustment– Adjusts horizontal angle up to

360º– Adjusts vertical angle

Feeding System

Ball feeding– Holds up to six balls– Motor rotates the feeder – Plunger pushes balls into the

launch system

Firing System

Ball launching– Discs run by motors– Servo motor adjusts vertical

angle



Conclusion

The Fully Automated Soccer Trainer (FAST) features self positioning, computer vision, and machine learning and is developed for individual soccer training.
