Function Documentation

humanoid()

template<typename Scalar , int Options, template< typename, int > class JointCollectionTpl>

void pinocchio::buildModels::humanoid	(	ModelTpl< Scalar, Options, JointCollectionTpl > &	model,
		bool	usingFF = true
	)

Create a 28-DOF kinematic chain of a floating humanoid robot.

The kinematic chain has four 6-DOF limbs shoulder-elbow-wrist, one 2-DOF torso, one 2-DOF neck. The float joint is either a JointModelFreeFloating (with nq=7 and nv=6), or a composite joint with a JointModelTranslation and a roll-pitch-yaw joint JointModelSphericalZYX (with total nq=nv=6). Using a free-floating or a composite joint is decided by the boolean usingFF.

Parameters

model	model, typically given empty, where the kinematic chain is added.
usingFF	if True, implement the chain with a plain JointModelFreeFloating; if False, uses a composite joint. This changes the size of the configuration space (35 vs 34).

humanoidRandom()

template<typename Scalar , int Options, template< typename, int > class JointCollectionTpl>

void pinocchio::buildModels::humanoidRandom	(	ModelTpl< Scalar, Options, JointCollectionTpl > &	model,
		bool	usingFF = true
	)

Create a humanoid kinematic tree with 6-DOF limbs and random joint placements.

This method is only meant to be used in unittest. Due to random placement and masses, the resulting model is likely to not correspond to any physically-plausible model. You may want to consider pinocchio::humanoid and pinocchio::humanoidGeometries functions that rather define a plain and non-random model.

Parameters

model	model, typically given empty, where the kinematic chain is added.
usingFF	if True, implement the chain with a plain JointModelFreeFloating; if False, uses a composite joint translation + roll-pitch-yaw. This changes the size of the configuration space (33 vs 32).

manipulator()

template<typename Scalar , int Options, template< typename, int > class JointCollectionTpl>

void pinocchio::buildModels::manipulator

(

ModelTpl< Scalar, Options, JointCollectionTpl > &

model

)

Create a 6-DOF kinematic chain shoulder-elbow-wrist.

Parameters

model

model, typically given empty, where the kinematic chain is added.
