mrpt::nav::CPTG_Holo_Blend Class Reference

Detailed Description

A PTG for circular-shaped robots with holonomic kinematics.

• Compatible kinematics: Holonomic robot capable of velocity commands with a linear interpolation ("ramp "or "blending") time. See mrpt::kinematics::CVehicleSimul_Holo
• Compatible robot shape: Circular robots
• PTG parameters: Use the app ptg-configurator

maxTimeInVelCmdNOP()

double CPTG_Holo_Blend::maxTimeInVelCmdNOP ( int  path_k ) const

overridevirtual

Only for PTGs supporting supportVelCmdNOP(): this is the maximum time (in seconds) for which the path can be followed without re-issuing a new velcmd.

Note that this is only an absolute maximum duration, navigation implementations will check for many other conditions. Default method in the base virtual class returns 0.

Parameters

path_k

Queried path k index [0,N-1]

void CPTG_Holo_Blend::updateTPObstacle ( double  ox, double  oy, std::vector< double > &  tp_obstacles  ) const

Parameters

[in,out]	tp_obstacles	A vector of length getAlphaValuesCount(), initialized with initTPObstacles() (collision-free ranges, in "pseudometers", un-normalized).
[in]	ox	Obstacle point (X), relative coordinates wrt origin of the PTG.
[in]	oy	Obstacle point (Y), relative coordinates wrt origin of the PTG.

Note

The length of tp_obstacles is not checked for efficiency since this method is potentially called thousands of times per navigation timestap, so it is left to the user responsibility to provide a valid buffer.

tp_obstacles must be initialized with initTPObstacle() before call.
