Update Notifiers

Get spring force

We apply spring force in implicit manner. The spring force is F = -(springStiffness * q(k+1)), where q(k+1) is approximated as q(k) + h * dq(k) * h^2 * ddq(k). Since, in the recursive forward dynamics algorithm, ddq(k) is unknown variable that we want to obtain as the result, the spring force here is just F = -springStiffness * (q(k) + h * dq(k)) and -springStiffness * h^2 * ddq(k) term is rearranged at the recursive forward dynamics algorithm, and it affects on the articulated inertia.

See also: BodyNode::updateArticulatedInertia(double).

Parameters

[in] _timeStep Time step used for approximating q(k+1). Get damping force

We apply the damping force in implicit manner. The damping force is F = -(dampingCoefficient * dq(k+1)), where dq(k+1) is approximated as dq(k) + h * ddq(k). Since, in the recursive forward dynamics algorithm, ddq(k) is unknown variable that we want to obtain as the result, the damping force here is just F = -(dampingCoefficient * dq(k)) and -dampingCoefficient * h * ddq(k) term is rearranged at the recursive forward dynamics algorithm, and it affects on the articulated inertia.

[in]	_renameDofs	If true, the names of the joint's degrees of freedom will be updated by calling updateDegreeOfFreedomNames().

[in]	_bodyForce	Transmitting spatial body force from the parent BodyNode to the child BodyNode. The spatial force is expressed in the child BodyNode's frame.
