4 Navigation PROJECT BACKGROUND Oldest & Universal Sport 3.5 Billion Fans Vital Component Ref: 1,2,3

5 Navigation o Penalty kick stat: Only 12% goalie save rate! Our project will attempt to aid in the solo soccer training process to improve the chances of successfully saving a goal. PROJECT BACKGROUND Ref: 4

6 Navigation HOWS IT DIFFERENT?? o Many sports machines. Ref: 5,6,7

7 Navigation HOWS IT DIFFERENT?? o Many sports machines. o Previous design projects. Ref: 8,9

8 Navigation o Many sports machines. o Previous design projects. Differences: Largest object launched Largest object launched Only the goalie Only the goalie Randomized Randomized Automatic Automatic Self Feed Self Feed HOWS IT DIFFERENT?? Ref: 10
