Answer key, but looking at it takes away the fun
D = down, L = left, R = right
Levels numbers correspond to the ones in roboarm2.codea
Level 1:
F1: D,R,D
Level 2:
F1: D,R,D,F1
Level 3:
F1: D,R,D,L,F1
Level 4:
brute force solution:
F1: D,F2,D,F3,F1
F2: R,R,R,R,R
F3: L,L,L,L,L
shorter solution:
F1: F2,F2,F2,F2,F2
F2: F3,F3,F3,F3,R
F3: D,R,D,L
Level 5:
