Orthodox Chebyshev Bi-pedal walking apparatus. Perhaps, the most simple implementation.
Trick: Suppose, I notate a = Vector of a →. --- i.e. under bar _ represents →. mean of (a+b) = 0.5(a+b). mean of [(a+c) + (b-c)] = 0.5(a+b) Also, 0.5(a+b) = 0.5a +0.5b Please consider above meaning. (i.e. The mean/ means , and, its meaning.) [ex. typical sample: always, AM = 0.5 B'E + 0.5 BB'1 ---- why? ---- evident. ] Information: Red Bullet B● is on the (1, 0) case; --- point M is just (0, 4) ∵ BF = 3 (base), BE = 5 , so EF = 4 [√(25-9)] --- i.e. height is just 4 (0, -1) case; --- M is just (2, 4) ∵ B'2E = 4 (base), B'E = 5 , so B'2B' = 3, so AB'2 = 1 + 3 = 4 --- i.e. height is just 4 ■ Other sample: ---- this is very educational. Novice/ Beginners are apt to implement it like other typical sample. ① TLT15 [チェビシェフリンク2足歩行ロボット]  ----- Japanese site, but picture is international. The same function, but (3+4 bars + rectangle rigid boy)/ leg 3+4 can reduce to 4+1. --- i.e. 2 bars are over than my method.  --- But, To avoid the bar confliction, 4 sides are required in crank system. Implementation is not easy.

Caster (wikipedia) ● Wheelchair ----- big wheel replace, good cost. good horizontality, bad operability (difficulty of curve managing ? --- be able to improve, perhaps.). cf.
