Member Function Documentation

◆ computeInstruments()

std::vector< TrackingInstrument > computeInstruments ( const RobotState & robotState) const
overrideprotectedvirtual

Convert robot state into tracking instruments.

Returns
tracking instruments for the flange and end-effector, with fallback mechanism. Retrieve the flange-to-world transformation or fall back to retrieving the flange name from the robot model. Then, retrieve the named-link transformation based on the obtained flange name.
Note
Return empty vector if both fail. Retrieve the effector-to-world transformation or fall back to forward kinematic calculation.
Otherwise log an error.

Reimplemented from RobotTrackingStream.
