Goal: recognize ball trajectory, QUICKLY assume position.Ball trajectory: A serves to B, B passes to C.Walking direction: A, B, C
B moves (before the ball has passed the 3m line of A) to the right position (90%) and is active instead of reactive.B assumes the correct posture when the ball passes the netB adjust the correct position and posture in the remaining position (10%).
Possibly build up:- first B catches ball with bent arms- B then passes the ball underhand
