Team 39 AeroBot Kick

[offliner62]

Saw your robot at the Las Vegas Regionals and am impressed by your mobility, controls and targeting system.

Noticed that you keep bouncing **** up into the backstop and target area.

I have done extensive analysis of the flight machanics of soccer ****
and think I have zeroe'd in on the key to scoring shots on goal.

My model predicts the flight of a ball every 100th of a second and predicts the kicking force,
shooting angle, and necessary top spin to land every shot on goal.

If you have ever driven a golf ball or watched a professional soccer player kick a free shot on goal,
TOP SPIN IS VERY IMPORTANT. You can read aobut the Magnus force in flight mechanics.
when you impart TOP SPIN ON THE BALL, the Magnus force drives the ball in the direction of the spin.

This is why an amateur golfer slices the ball when they fail to break their wrist when driving the ball.
It spins out of control away from the swing.

Team 39 lifts the ball like a foot ball player.
This is the same as a field goal kicker.
In soccer, you need to drive the ball down to the goal.
If the ball is short it will still roll into the goal.
With top spin you sill score a much higheer percentage of shots.

With bottom spin, the ball will check up like a chip shot in golf.

I came up with an ideal kicking angle of 22 degrees, 78 lbs force, and top spin in order to score from the middle zone.
The team came up with a clever cam mechanism to restore the pin-ball plunger at the end of each shot.

Good luck in your future adventures.
You have an awesome robot.
