Detailed Description

SpineFeedbackControl learns the parameters for a CPG system on a spine like tensegrity structure specified as a BaseSpineModelLearning. Parameters are generated by AnnealEvolution and used in the CPGEquations family of classes. tgImpedanceController controllers are used for the detailed muscle control. Due to the number of parameters, the learned parameters are split into one config file for the nodes and another for the CPG's "edges"

Constructor & Destructor Documentation

SpineFeedbackControl::SpineFeedbackControl ( SpineFeedbackControl::Config  config,
std::string  args,
std::string  resourcePath = "",
std::string  ec = "edgeConfig.ini",
std::string  nc = "nodeConfig.ini",
std::string  fc = "feedbackConfig.ini" 
)

Defining the adapters here assumes the controller is around and attached for the lifecycle of the learning runs. I.E. that the setup and teardown functions are used for tgModel

Member Function Documentation

void tgSubject< BaseSpineCPGControl >::attach ( tgObserver< BaseSpineCPGControl > *  pObserver)
inherited

Attach an observer to the subject of the observer.

Parameters
[in,out]pObservera pointer to an observer for the subject; do nothing if the pointer is NULL
void tgSubject< BaseSpineCPGControl >::notifySetup ( )
inherited

Call tgObserver<T>::onSetup() on all observers in the order in which they were attached.

Here is the caller graph for this function:

void tgSubject< BaseSpineCPGControl >::notifyStep ( double  dt)
inherited

Call tgObserver<T>::onStep() on all observers in the order in which they were attached.

Parameters
[in]dtthe number of seconds since the previous call; do nothing if not positive
void tgSubject< BaseSpineCPGControl >::notifyTeardown ( )
inherited

Call tgObserver<T>::onTeardown() on all observers in the order in which they were attached.

Here is the caller graph for this function:

virtual void tgObserver< BaseSpineModelLearning >::onAttach ( BaseSpineModelLearning subject)
inlinevirtualinherited

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

Parameters
[in,out]subjectthe subject being observed

Definition at line 55 of file tgObserver.h.

void SpineFeedbackControl::onSetup ( BaseSpineModelLearning subject)
virtual

Notify the observers when a setup action has occurred.

Parameters
[in,out]subjectthe subject being observed

Reimplemented from BaseSpineCPGControl.

Definition at line 122 of file SpineFeedbackControl.cpp.

void SpineFeedbackControl::onStep ( BaseSpineModelLearning 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:
add to config
Todo:
if bogus, stop trial (reset simulation)

Reimplemented from BaseSpineCPGControl.

Definition at line 159 of file SpineFeedbackControl.cpp.

void SpineFeedbackControl::onTeardown ( BaseSpineModelLearning subject)
virtual

Notify the observers when a teardown action has occurred.

Parameters
[in,out]subjectthe subject being observed
Todo:
  • consolidate with other controller classes.
Todo:
  • return length scale as a parameter

Reimplemented from BaseSpineCPGControl.

Definition at line 202 of file SpineFeedbackControl.cpp.

array_4D BaseSpineCPGControl::scaleEdgeActions ( std::vector< std::vector< double > >  actions)
protectedvirtualinherited

Takes a vector of parameters reported by learning, and then converts it into a format used to assign to the CPGEdges Note that if the CPG edges change, this will need to change
