Detailed Description

A class for connecting a central-up limb, a left and right limb of the iCub, and exchanging kinematic and wrench information between limbs, when both left/right limb have FT sensors and the central-up one use the kinematic and wrench information coming from a inertial measurements or another iDynSensorNode.

This is the base class of UpperTorso and LowerTorso. The connection between UpperTorso and LowerTorso is not handled here: it is simply supposed that a Torso Node receives correct kinematic and wrench input from outside.

Main method for solving kinematics and wrench among limbs, where information are shared.

This method assumes that the initial kinematics informations have already been set, as the external wrench on the central limb: i.e. this method is the one called after attachTorso().

Parameters

FM_right	a 6x1 vector with forces and moments measured by the FT sensor in the right limb
FM_left	a 6x1 vector with forces and moments measured by the FT sensor in the left limb

Returns: true if succeeds, false otherwise

◆ update() [3/3]

bool iCub::iDyn::iDynSensorTorsoNode::update	(	const yarp::sig::Vector &	w0,
		const yarp::sig::Vector &	dw0,
		const yarp::sig::Vector &	ddp0,
		const yarp::sig::Vector &	FM_right,
		const yarp::sig::Vector &	FM_left,
		const yarp::sig::Vector &	FM_up
	)

Main method for solving kinematics and wrench among limbs, where information are shared.

Parameters

w0	a 3x1 vector with the initial/measured angular velocity
dw0	a 3x1 vector with the initial/measured angular acceleration
ddp0	a 3x1 vector with the initial/measured linear acceleration
FM_right	a 6x1 vector with forces and moments measured by the FT sensor in the right limb
FM_left	a 6x1 vector with forces and moments measured by the FT sensor in the left limb
FM_up	a 6x1 vector with forces and moments initializing the central limb

Returns: true if succeeds, false otherwise
