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__) = 0.5

__a__+0.5

__b__Please consider above meaning. (i.e. The mean/ means , and, its meaning.) [ex. typical sample: always,

**---- why? ---- evident. ]**

__AM__= 0.5__B'E__+ 0.5__BB'1__**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'

_{2}E = 4 (base), B'E = 5 , so B'

_{2}B' = 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.

**② Chebyshev's Lambda Mechanism (wikipedia) ③ The Chebyshev Walking Machine ④ CHEBYSHEV MULTIPLE-BAR WALKING MECHANISM ⑤ walking Chebyshev's (YouTube) --- design miss? but, educational.**

**■ New type wheel**● Above apparatus becomes a new type caster (on the carpet etc) . cf. Caster (wikipedia) ● Wheelchair ----- big wheel replace, good cost. good horizontality, bad operability (difficulty of curve managing ? --- be able to improve, perhaps.). cf. Wheelchair (wikipedia) ● Walker (mobility) (wikipedia) rollator, Silver-car (Name in Japan) (wikipedia) ● Crutch Underarm or axilla
