odometry

(robotics)
The use of motion sensors to determine a robot's change in position relative to some known position. For example, if a robot is traveling in a straight line and if it knows the diameter of its wheels, then by counting the number of wheel revolutions it can determine how far it has traveled. Robots will often have shaft encoders attached to their drive wheels which emit a fixed number of pulses per revolution. By counting these pulses, the processor can estimate the distance traveled.

The hardware framework also includes two encoders assembled on the wheels (allowing the tools to measure distance, speed, and position) and a webcam to re ad artificial landmarks and refine the odometry.
MTM inspection is unique to ECDA techniques because it passively measures the magnetic flux of a pipeline while simultaneously recording odometry.
