1.1 Purpose: 1.1.1 The purpose of this test method is to evaluate an A-unmanned ground vehicle’s (A-UGV) capability of traversing through a defined space with limited A-UGV clearance. This test method is intended for use by A-UGV manufacturers, installers, and users. This test method defines a set of generic 2D area shapes representative of user applications and for different A-UGV types. 1.1.2 A-UGVs shall possess a certain set of navigation capabilities appropriate to A-UGV operations such as A-UGV movement between structures that define the vehicle path. A navigation system is the monitoring and controlling functions of the A-UGV, providing frequent A-UGV updates of vehicle movement from one place to another. A-UGV environments often include various constraints to A-UGV mobility. In this test method, apparatuses, procedures, tasks, and metrics are specified that apply constraints and thereby, standard test methods for determining an A-UGV’s navigation capabilities are defined. 1.1.3 This test method is scalable to provide a range of dimensions to constrain the A-UGV mobility during task performance. 1.1.4 A-UGVs shall be able to handle many types of open and defined area complexities with appropriate precision and accuracy to perform a particular task.
