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 for the CPG's "edges"

Constructor & Destructor Documentation

JSONStatsFeedbackControl::JSONStatsFeedbackControl	(	JSONStatsFeedbackControl::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< JSONQuadCPGControl >::attach ( tgObserver< JSONQuadCPGControl > *  pObserver )

inherited

Attach an observer to the subject of the observer.

Parameters

[in,out]

pObserver

a pointer to an observer for the subject; do nothing if the pointer is NULL

void tgSubject< JSONQuadCPGControl >::notifySetup ( )

inherited

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

void tgSubject< JSONQuadCPGControl >::notifyStep ( double  dt )

inherited

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

Parameters

[in]

dt

the number of seconds since the previous call; do nothing if not positive

void tgSubject< JSONQuadCPGControl >::notifyTeardown ( )

inherited

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

virtual void tgObserver< BaseQuadModelLearning >::onAttach ( BaseQuadModelLearning &  subject )

inlinevirtualinherited

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

Parameters

[in,out]

subject

the subject being observed

Definition at line 55 of file tgObserver.h.

void JSONStatsFeedbackControl::onSetup ( BaseQuadModelLearning &  subject )

virtual

Notify the observers when a setup action has occurred.

Parameters

[in,out]

subject

the subject being observed

Reimplemented from JSONQuadCPGControl.

Definition at line 120 of file JSONStatsFeedbackControl.cpp.

Here is the call graph for this function:

void JSONStatsFeedbackControl::onStep ( BaseQuadModelLearning &  subject, double  dt  )

virtual

Notify the observers when a step action has occurred.

Parameters

[in,out]	subject	the subject being observed
[in]	the	number of seconds since the previous call; must be positive

Max and min heights added to config

Todo:

if bogus, stop trial (reset simulation)

void JSONStatsFeedbackControl::onTeardown ( BaseQuadModelLearning &  subject )

virtual

Notify the observers when a teardown action has occurred.

Parameters

[in,out]

subject

the subject being observed

Todo:

• consolidate with other controller classes.

Todo:

• return length scale as a parameter

Here is the call graph for this function:

array_4D JSONQuadCPGControl::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
