cossack-walk

From a deep squat (root.y~-0.45), shoot one straight leg forward, then the other — the classic squat-kick.

Composes: move-leg + bend-knees + balance-and-posture

How

• Use a sequence with loop:true. Stay deep (root.y:-0.45).
• Kicking leg: thigh forward + knee straight (UpLeg:[90,0,0],Leg:0). Support leg deeply folded (UpLeg~60,Leg~120).
• durationMs per cycle ~2200.

Example

• "do a cossack dance" -> {"durationMs":2200,"say":"Hey! Hey! Hey!","sequence":{"loop":true,"frames":[{"t":0,"pose":{"LeftUpLeg":[90,0,0],"LeftLeg":[0,0,0],"RightUpLeg":[60,0,0],"RightLeg":[120,0,0]},"root":{"y":-0.45}},{"t":0.5,"pose":{"RightUpLeg":[90,0,0],"RightLeg":[0,0,0],"LeftUpLeg":[60,0,0],"LeftLeg":[120,0,0]},"root":{"y":-0.45}},{"t":1,"pose":{"LeftUpLeg":[90,0,0],"LeftLeg":[0,0,0],"RightUpLeg":[60,0,0],"RightLeg":[120,0,0]},"root":{"y":-0.45}}]}}

Limits & posture

Keep ≥1 foot grounded except at a jump's airborne apex; stay inside human joint ranges and keep weight over the support — see balance-and-posture.
