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.
Using a three-dimensional map preloaded into the robot, a set of laser rangefinders, and sophisticated odometry algorithms, robots can self-localize within the building in reference to the map.
The scaled vehicle was complementary equipped with ultrasonic sensor clusters for the object identification in range of up to 700 [mm], a PC-104 unit interface for computing the real time embedded algorithms using the xPC tool from Matlab and odometry sensors as represented in the figure below.
It is important to remark that the original wheelchair has undergone minimal modifications: two encoders have been connected to the motors' axis to estimate the wheelchair odometry and the original battery's voltmeter, as well as the joystick line, have been bypassed to several microcontrollers placed bellow the batteries' cage.
The standard GPS receiver position has been improved using inertial measurements, odometry, and optimal filtering.
Finally, the robot is able to accumulate the reconstruction of the visited environment (in the form of a 3D map) as it navigates, using odometry and tracking.
Nurses are now required to undertake odometry testing, blood testing, cholesterol testing as well as providing sickness absence management.
The vehicle is able to travel a short distance off the guide wire and return to another path, using the vehicle's on-board programming and odometry for guidance.
