Significance and Use

5.1 These test methods are part of an overall suite of related test methods that provide repeatable measures of human-system interaction capability including robotic system mobility, dexterity, inspection, remote operator proficiency, and situational awareness. In particular, the operator control unit (OCU) design and interface features may impact the operator’s ability to perform movement and inspection tasks with the robot.

5.2 The test apparatuses are low cost and easy to fabricate so they can be widely replicated. The procedure is also simple to conduct. This eases comparisons across various testing locations, dates, and times to determine best-in-class systems and operators.

5.3 Evaluation—These test methods can be used in a controlled environment to measure baseline capabilities. They can also be embedded into operational training scenarios to measure degradation due to uncontrolled variables in lighting, weather, radio communications, GPS accuracy, etc.

5.4 Procurement—These test methods 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—These test methods can be used to focus operator training, as a repeatable practice task or as an embedded task within training scenarios. The resulting measures of remote operator proficiency enable tracking of perishable skills over time, along with comparisons of performance across squads, regions, or national averages.

5.6 Innovation—These test methods 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 test methods can guide manufacturers toward implementing the combinations of capabilities necessary to perform essential mission tasks.

Scope

1.1 These test methods are intended for remotely operated ground robots operating in complex, unstructured, and often hazardous environments. They specify the apparatuses, procedures, and performance metrics necessary to measure the capability of a robot to dexterously inspect objects of interest in the environment at various heights, depths, orientations, and confinement. This standard is one of several related dexterity tests that can be used to evaluate overall system capabilities. Three test methods are included in this standard: linear dexterity, omni-directional dexterity, and combination dexterity. All test methods use the same apparatus components (Section 6), pose the same hazards (Section 7), use the same procedure (Section 8), the same precision and bias (Section 9), and the same keywords (Section 16). The combination dexterity test method uses additional apparatus components (Section 10), has its own metrics (Section 11), and report (Section 12). The linear dexterity and omni-directional dexterity test methods use additional apparatus components (Section 13), their own metrics (Section 14), and report (Section 15). Appendix X2 contains example filled out report forms for all test methods.

1.2 The robotic system typically includes a remote operator 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 these test methods for various mission requirements.

1.4 Performing Location—These test methods may be performed anywhere the specified apparatuses and environmental conditions can be implemented.

1.5 Units—The International System of Units (SI Units) and U.S. Customary Units (Imperial Units) are used throughout this test method. They are not mathematical conversions. Rather, they are approximate equivalents in each system of units to enable 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 these test methods.

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.
