mrpt::nav::CHolonomicVFF Class Reference

Detailed Description

A holonomic reactive navigation method, based on Virtual Force Fields (VFF).

These are the optional parameters of the method which can be set by means of a configuration file passed to the constructor or to CHolonomicND::initialize (see also the field CHolonomicVFF::options).

# Section name can be changed via setConfigFileSectionName()
[VFF_CONFIG]
TARGET_SLOW_APPROACHING_DISTANCE = 0.10 // For stopping gradually
TARGET_ATTRACTIVE_FORCE = 20 // Dimension-less (may have to be tuned depending on the density of obstacle sampling)

Introduces a pure virtual method responsible for writing to a mxArray Matlab object, typically a MATLAB struct whose contents are documented in each derived class.

Introduces a pure virtual method responsible for writing to a CStream.

This can not be used directly be users, instead use "stream << object;" for writing it to a stream.

Parameters
outThe output binary stream where object must be dumped.
getVersionIf NULL, the object must be dumped. If not, only the version of the object dump must be returned in this pointer. This enables the versioning of objects dumping and backward compatibility with previously stored data.
