Typedefs

typedef std::shared_ptr<mrpt::kinematics ::CVehicleVelCmd_DiffDriven> Ptr

A type for the associated smart pointer.

Fields

double lin_vel {.0}

Linear velocity (m/s)

double ang_vel {.0}

Angular velocity (rad/s)

Methods

virtual const mrpt::rtti::TRuntimeClassId* GetRuntimeClass() const

Returns information about the class of an object in runtime.

virtual mrpt::rtti::CObject* clone() const

Returns a deep copy (clone) of the object, indepently of its class.

virtual size_t getVelCmdLength() const

Get number of components in each velocity command.

virtual std::string getVelCmdDescription(const int index) const

Get textual, human-readable description of each velocity command component.

virtual double getVelCmdElement(const int index) const

Get each velocity command component.

virtual void setVelCmdElement(const int index, const double val)

Set each velocity command component.

virtual bool isStopCmd() const

Returns true if the command means “do not move” / “stop”.

See also:

setToStop

virtual void setToStop()

Set to a command that means “do not move” / “stop”.

See also:

isStopCmd

virtual void cmdVel_scale(double vel_scale)

See docs of method in base class.

The implementation for differential-driven robots of this method just multiplies all the components of vel_cmd times vel_scale, which is appropriate for differential-driven kinematic models (v,w).

virtual double cmdVel_limits(
    const mrpt::kinematics::CVehicleVelCmd& prev_vel_cmd,
    const double beta,
    const TVelCmdParams& params
    )

See base class docs.

Tecognizes these parameters: robotMax_V_mps, robotMax_W_degps
