Struct JointModelPrismatic 

pub struct JointModelPrismatic {
    pub axis: SpatialMotion,
    pub limits: JointLimits,
    pub bias: SpatialMotion,
}

Model of a prismatic joint.

This joint constraints two objects to translate along a given axis.

Fields

axis: SpatialMotion

The axis of translation expressed in the local frame of the joint.

limits: JointLimits

The joint limits.

bias: SpatialMotion

The (null) bias of the joint.

Implementations

impl JointModelPrismatic

pub fn new(axis: Vector3D) -> Self

Creates a new JointModelPrismatic with the given axis of translation and unbounded limits.

The axis of translation should be normalized and expressed in the local frame of the joint.

Arguments

• axis - The normalized axis of translation expressed in the local frame of the joint.

Returns

A new JointModelPrismatic object.

pub fn new_px() -> Self

Creates a new prismatic joint model with x as axis of translation.

Returns

A new JointModelPrismatic object.

pub fn new_py() -> Self

Creates a new prismatic joint model with y as axis of translation.

Returns

A new JointModelPrismatic object.

pub fn new_pz() -> Self

Creates a new prismatic joint model with z as axis of translation.

Returns

A new JointModelPrismatic object.
