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. 1.1.5 The required mobility capabilities include preprogrammed or autonomous movement or both from a start point to an end point. Further mobility requirements may include: sustained speeds, vehicle reconfiguration to pass through defined spaces, payload, A-UGV movement within constrained volumes, or other vehicle capabilities, or combinations thereof. This test method is designed such that a candidate A-UGV can be evaluated as to whether or not it meets a set of user application requirements. 1.1.6 Performing Location—This test method shall be performed in a location where the apparatus and environmental test conditions can be full
