The stripe can be divided into several image points and the range can be calculated for each point. Sensor - Instruments used as input devices for robots which enable it to determine aspects regarding the robot's environment, as well as the robot's own positioning. Sensors are used for robot information, and robot control. Path Planning - A method of path planning for a robot which uses a dynamic world model. The robot uses sensors to evaluate it's environment.
Computer simulation is executed by a computer program to test and plan the robots actions.
Several simulations may be needed to successfully plan the robots actions before the robot is allowed to execute it's procedure. See Model Based Path Planning. Sensor Fusion - Determining many different attributes of an object using different sensors together. See Correlation, and Entitizing. The controller sends an error signal to the robot.
