1.1 This test method is intended for remotely operated ground robots using radio communications to transmit real-time data between a robot and its remote operator interface. This test method measures the maximum line-of-sight radio communications distance at which a robot can maintain omnidirectional steering, speed control, precise stopping, visual acuity, and other functionality. This test method is one of several related radio communication tests that can be used to evaluate overall system capabilities. 1.2 A remote operator is in control of all functionality, so an onboard camera and remote operator display are typically required. Assistive features or autonomous behaviors may improve the effectiveness or efficiency of the overall system. 1.3 Different user communities can set their own thresholds of acceptable performance within this test method to address various mission requirements. 1.4 Performing Location— This test method may be performed anywhere the specified apparatuses and environmental conditions can be implemented. 1.5 The International System of Units (a.k.a. SI Units) and U.S. Customary Units (a.k.a. Imperial Units) are used throughout this document. They are not mathematical conversions. Rather, they are approximate equivalents in each system of units to enable the use of readily available materials in different countries. The differences between the stated dimensions in each system of units are insignificant for the purposes of comparing test method results, so each system of units is separately considered standard within this test method. 1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. 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. 1.7 This 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. ====== Significance And Use ====== 5.1 This test method is part of an overall suite of related tests that provide reproducible measures of radio communications for remotely operated robots. It measures the maximum line-of-sight radio communications range between a robot and its remote operator interface using omnidirectional robot maneuvering and visual acuity tasks to evaluate the degradation of essential mission capabilities due to communications latency and loss. 5.2 This test method is inexpensive, easy to fabricate, and simple to conduct so it can be replicated widely. This enables comparisons across various testing locations and dates to determine best-in-class system capabilities and remote operator proficiency. 5.3 Evaluations— This test method can be conducted in a controlled environment with no radio frequency interference and minimal radio propagation effects to measure baseline capabilities that can be compared widely across robotic systems. It also can be embedded into any operational training scenario as a practical measure of line-of-sight radio communications range with additional degradation due to uncontrolled variables such as radio frequency interference, weather, etc. The results of these scenario tests can be compared across robotic systems only when conducted in the same environment in similar conditions. However, the results cannot be compared reliably to results from other venues or environmental conditions due to the uncontrolled variables. 5.4 Procurement— This test method can be used to identify inherent capability trade-offs in systems, make informed purchasing decisions, and verify performance during acceptance testing. This aligns requirement specifications and user expectations with existing capability limits. 5.5 Training— This test method can be used to focus operator training as a repeatable practice task or as an embedded task within training scenarios. Operators can learn system behaviors during radio communication degradation and refine techniques to mitigate issues while performing tasks. The resulting measures of remote operator proficiency enable tracking of perishable skills over time, along with comparisons of performance across organizations, regions, or national averages. 5.6 Innovation— This test method can be used to inspire technical innovation, demonstrate break-through capabilities, and measure the reliability of systems performing specific tasks within an overall mission sequence. Combining or sequencing multiple tests can guide manufacturers toward implementing the combinations of capabilities necessary to perform essential mission tasks.
