mrpt::obs::CActionRobotMovement2D Class Reference

Detailed Description

Represents a probabilistic 2D movement of the robot mobile base.

See docs: https://www.mrpt.org/tutorials/programming/odometry-and-motion-models/probabilistic_motion_models/

Note
[New in MRPT 1.5.0] Velocity is now encoded as mrpt::math::TTwist2D as a more general version of the old (linVel, angVel).
