Detailed Description

JSONFeedbackControl 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 3 for the CPG's "edges".

Constructor & Destructor Documentation

JSONMixedLearningControl::JSONMixedLearningControl ( JSONMixedLearningControl::Config  config,
std::string  args,
std::string  resourcePath = "" 
)

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< JSONCPGControl >::attach ( tgObserver< JSONCPGControl > *  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< JSONCPGControl >::notifySetup ( )
inherited

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

void tgSubject< JSONCPGControl >::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< JSONCPGControl >::notifyTeardown ( )
inherited

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

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

array_4D JSONCPGControl::scaleEdgeActions ( Json::Value  edgeParam)
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

Todo:
consider adding exception here
