Here are some test walkcycles I did for each of the characters. I tried to get different feels of walks for each character. These are just rough tests.
R.A.M is very short, so he has to hop quite quickly.
The Professor is very energetic and optimistsic. He walks with the classic 8 frame double bounce walk. Notice the lower set of arms are slightly delayed.
Susie-May glides across the floor not moving her head at all. She swings her hips and shoulders for sassyiness.
Mort has a great deal of weight so has to shift that weight we he walks. He takes 16 frames.
