fast-feet

Rapid tiny in-place steps in a low ready stance — pure quickness, no travel.

Composes: move-leg + balance-and-posture

How

• Use a sequence with loop:true. No root translation (in place).
• Tiny fast alternating knee lifts (UpLeg~25,Leg30); stay low (Spine+X8).
• Short durationMs per cycle (~1200).

Example

• "fast feet" -> {"durationMs":1200,"say":"Fast feet!","sequence":{"loop":true,"frames":[{"t":0,"pose":{"LeftUpLeg":[25,0,0],"LeftLeg":[30,0,0],"Spine":[8,0,0]}},{"t":0.5,"pose":{"RightUpLeg":[25,0,0],"RightLeg":[30,0,0],"LeftUpLeg":[0,0,180],"LeftLeg":[0,0,0]}},{"t":1,"pose":{"LeftUpLeg":[25,0,0],"LeftLeg":[30,0,0],"RightUpLeg":[0,0,180],"RightLeg":[0,0,0]}}]}}

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.
