Are the turtlesim examples of moving in a straight line and rotating considered dead-reckoning?
I am not yet very familiar with the concepts in robotics. However, it seems to me that the examples described at http://wiki.ros.org/turtlesim/Tutorials/Moving%20in%20a%20Straight%20Line and http://wiki.ros.org/turtlesim/Tutorials/Rotating%20Left%20and%20Right are examples of dead-reckoning, given that we are basically estimating the traveled distance and the turned angle based respectively on an assumed linear and angular speeds and given a certain time has passed.
Is this correct?
