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.

Multisensors system fuses a stereo-camera sensor, inertial measurement units (IMU), and LRF odometry with an EKF algorithm to ensure robust, low-latency performance of SLAM.
Previously, most existing 3D mapping solutions either eliminate sensor motion by taking a stop-and-scan approach or attempt to correct the motion using odometric sensors, such as wheel or visual odometry. Many researchers take the approach of frequently stopping the platform in order to take a stationary scan [19].
To develop the robot, the team used off-the-shelf hardware, including a laser scanner for localisation and to collect data points of the environment, a camera looking for eggs, and odometry that guides velocity, acceleration and directional changes.

This is done by implementing the entire localization and mapping process, in which the LIDAR/Inertial Odometry algorithm presented in [52] is in charge of the localization step.
