mechanical, lower-cost. omnidirectional locomotion.
Say we tried to take two steps forward,
first with our ‘free-foot’, and then another with our ‘anchored-foot’.
#1 : Free-Foot Step Forward
#2 : Anchored-Foot Step Forward
This is very much the walking we’re used to. The free-foot moves infront of the anchored-foot, just like a traditional walking step.
When the anchored-foot attempts to move forwards, it can still travel vertically as the user lifts the foot to step forward, but the actual horizontal travel is pushed onto the other foot, the contraints of the anchored-foot exerting a force on the only free-moving point, the free-foot, pushing it backwards on it’s low-friction pads, helped initially by the sloped edges.
The walking motion is the same, but one foot always
remains horizontally fixed, and everything else moves around it.
“two steps forward, one step back”
Few unique parts, almost entirely simple mechanical elements for easier manafacture.
