This another mechanical walking robot design to go with all the others I have posted here and on youtube.

I call this action Heel and toe, or the Goose step. There is a roller in the heel of the feet and grip in the toe the legs and feet move as one part on a can action so that the foot can roll forward on the heel and then grab by the toes to advance that foot.
