soccer trainer Answered

Hey guys, I am currently a student with a very weak coding/application background. I researched and got the basics down but its all comes down to logic and hardware.Currently I am building a soccer trainer robot that can be controlled via android app.The user utilizes a xy coordinate system to move the robot to shoot the soccer balls at that player at various speeds and angles. Basically, the android app routine is

User inputs settings - > (random/preset) training -> moves robot to desired location on interactive xy gridlayout (soccerfield) -> send signals to arduino to shoot soccer balls at different speeds and angles at the user

I was wondering what programs and languages I would need to know for me to develop this application. Any help would be great. Thank you!
