Member Function Documentation

void tgCPGMGActuatorControl::assignNodeNumber ( CPGEquations &  CPGSys,
array_2D  nodeParams 
)

Can call these any time, but they'll only have the intended effect after all of the strings have been constructed.

Definition at line 103 of file tgCPGMGActuatorControl.cpp.

const CPGEquations* tgCPGMGActuatorControl::getCPGSys ( ) const
inline

Pointer to the CPG system. Owned by the higher level controller

Definition at line 80 of file tgCPGMGActuatorControl.h.

Here is the caller graph for this function:

void tgCPGMGActuatorControl::onAttach ( tgSpringCableActuator &  subject)
virtual

Notify the observers when an attach action has occurred. Will only occur once, typically before setup

Parameters
[in,out]subjectthe subject being observed

Reimplemented from tgObserver< tgSpringCableActuator >.

Definition at line 65 of file tgCPGMGActuatorControl.cpp.

virtual void tgObserver< tgSpringCableActuator >::onSetup ( tgSpringCableActuator &  subject)
inlinevirtualinherited

Notify the observers when a setup action has occurred.

Parameters
[in,out]subjectthe subject being observed

Reimplemented in tgCPGMGCableControl, and tgCPGCableControl.

Definition at line 61 of file tgObserver.h.

void tgCPGMGActuatorControl::onStep ( tgSpringCableActuator &  subject,
double  dt 
)
virtual

Notify the observers when a step action has occurred.

Parameters
[in,out]subjectthe subject being observed
[in]thenumber of seconds since the previous call; must be positive
Todo:
this fails if its attached to multiple controllers! is there a way to track global time at this level

Implements tgObserver< tgSpringCableActuator >.

Reimplemented in tgCPGMGCableControl.

Definition at line 80 of file tgCPGMGActuatorControl.cpp.

Here is the call graph for this function:

virtual void tgObserver< tgSpringCableActuator >::onTeardown ( tgSpringCableActuator &  subject)
inlinevirtualinherited

Notify the observers when a teardown action has occurred.

Parameters
[in,out]subjectthe subject being observed

Definition at line 67 of file tgObserver.h.

void tgCPGMGActuatorControl::setConnectivity ( const std::vector< tgCPGMGActuatorControl * > &  allStrings,
array_3D  edgeParams 
)

Iterate through all other tgSpringCableActuatorCPGInfos, and determine CPG network by rigid body connectivity

Definition at line 123 of file tgCPGMGActuatorControl.cpp.

Here is the call graph for this function:

Here is the caller graph for this function:

void tgBaseCPGNode::updateControlLength ( double  newControlLength)
inherited

Change the control length at runtime, sets m_controlLength to newControlLength newControlLength must be greater than or equal to zero.

Definition at line 102 of file tgBaseCPGNode.cpp.

void tgBaseCPGNode::updateTensionSetpoint ( double  newTension)
inherited

Give a new tension setpoint to the impedance controller m_pMotorControl

Member Data Documentation

const double tgCPGMGActuatorControl::m_controlStep
protected

How often this controller updates. Must be non-negative. Zero means it updates every timestep. Units are seconds

Definition at line 115 of file tgCPGMGActuatorControl.h.

double tgCPGMGActuatorControl::m_controlTime
protected

Member variable for keeping track of how long its been since the last update step

Definition at line 110 of file tgCPGMGActuatorControl.h.
