Member Function Documentation

double robJoint::ForceTorqueMax

(

)

const

Return the maximum force/torque.

Returns

The absolute value for the maximum force or torque that can be applied by the joint.

double robJoint::GetForceTorque

(

)

const

Return the joint force or torque.

If supported, this returns the joint force or torque.

Returns

The joint torque or force (no unit)

robJoint::Mode robJoint::GetMode

(

)

const

Return the mode of the joint.

Returns

The mode of the joint (active or passive)

double robJoint::GetPosition

(

)

const

Return the joint position.

If supported, this returns the joint position.

Returns

The joint angular or linear position (no unit)

robJoint::Type robJoint::GetType

(

)

const

Return the type of the joint.

Returns

The type of the joint (hinge, slider, universal, ball and socket)

double robJoint::GetVelocity

(

)

const

Return the joint velocity.

If supported, this returns the joint velocity.

Returns

The joint angular or linear velocity (no unit)

double robJoint::PositionMax

(

)

const

Return the maximum position.

Returns

The maximum position of the joint. This value has no unit.

double robJoint::PositionMin

(

)

const

Return the minimum position.

Returns

The minimum position of the joint. This value has no unit.

double robJoint::PositionOffset

(

)

const

Return the offset position.

Returns

The offset position of the joint. This value has no unit.

virtual robJoint::Errno robJoint::Read ( std::istream &  is )

virtual

Read from an input stream.

Use this method to configure the parameters of the joints from an input stream. The parameters are in the following order: type, mode, position offset, min position, max position, max force/torque.

Parameters

is[in]

The input stream

Reimplemented in robKinematics.

void robJoint::SetForceTorque

(

double

ft

)

Set the force/torque.

If supported, this sets the force/torque. The new value is NOT clipped to the force/torque limit.

Parameters

ft	The new force/torque

void robJoint::SetPosition

(

double

q

)

Set the joint position.

If supported, this sets the joint position. The position is NOT clipped to the position limits.

Parameters

q	The new joint angular or linear position

void robJoint::SetVelocity

(

double

qd

)

Set the joint velocity.

If supported, this sets the joint velocity. The velocity is NOT clipped to the velocity limit.

Parameters

qd	The new joint angular or linear velocity.

virtual robJoint::Errno robJoint::Write ( std::ostream &  os ) const

virtual

Read from an input stream.

Use this method to write the parameters of the joints to an output stream. This method can be overloaded for more specific joints.

Parameters

os[in]

The output stream

Reimplemented in robKinematics.
