Simple implementation viersion. cf1.  N=4 2R-Virtual Wheel (1st version.) cf2.  N=4 2R-Virtual Wheel (Vers.-B) (bariant -B:  exact line symmetry)
In above fig., C1V (pink) // B'D' (blue) is it true? If so, Green 3 bars can be replaced by 1 bar (= parallelizing from V to B'D' . ex. new bar VV'). Tip: C1V (pink) // B'D' (blue) is looks like true, but C1V (pink) is not // B'C' (green) is looks like true. ----- odd. --- WHY? Very odd. my drawing mistake??. This expection was failure. Purple line --- is real // line from B'. But we can use this as approximation solution, if you like. Perhaps, This foot doesn't dig a ground at landing time. c. Review: 0.41 = tan(45°/2) =tan(π/8) , where π = pi /pai/ =3.14.....
