teeter

A continuous teetering: rock back onto the heels then forward, arms windmilling to stay up.

Composes: balance-and-posture + move-arm + move-torso

How

• Use a sequence with loop:true; no root needed.
• Rock the torso back (Spine-X, heels, toes up) then forward (Spine+X), arms swinging the opposite way.
• durationMs per cycle ~1600.

Example

• "teeter on the edge" -> {"durationMs":1600,"say":"Teetering!","sequence":{"loop":true,"frames":[{"t":0,"pose":{"Spine":[-15,0,0],"LeftUpperArm":[0,0,30],"RightUpperArm":[0,0,-30],"LeftFoot":[120,0,0],"RightFoot":[120,0,0]}},{"t":0.5,"pose":{"Spine":[8,0,0],"LeftUpperArm":[0,0,140],"RightUpperArm":[0,0,-140]}},{"t":1,"pose":{"Spine":[-15,0,0],"LeftUpperArm":[0,0,30],"RightUpperArm":[0,0,-30]}}]}}

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.
