1.1Purpose:
1.1.1The 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.
1.1.2A-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.
1.1.3This test method is scalable to provide a range of dimensions to constrain the A-UGV mobility during task performance.
1.1.4A-UGVs shall be able to handle many types of open and defined area complexities with appropriate precision and accuracy to perform a particular task.
1.1.5The 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.
1.1.6Performing Location—This test method shall be performed in a location where the apparatus and environmental test conditions can be fully implemented. Environmental conditions are specified and recorded.
1.1.7Additional test methods within Committee F45 are anticipated to be developed to address additional or advanced mobility capability requirements.
1.2Units—The values stated in SI units are to be regarded as the standard. The values given in parentheses are not precise mathematical conversions to inch-pound units. They are close approximate equivalents for the purpose of specifying material dimensions or quantities that are readily available to avoid excessive fabrication costs of test apparatuses while maintaining repeatability and reproducibility of the test method results. These values given in parentheses are provided for information only and are not considered standard.
1.3This standard does not purport to address all of the safety concerns, if any, associated with its use. Safety standards such as ANSI/ITSDF B56.5, BS EN 1525, or other safety standards should be followed. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.4This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
