Standard Test Method for Evaluating Response Robot Mobility Using Variable Diagonal Rail Obstacles
SIGNIFICANCE AND USE
5.1 This test method is part of an overall suite of related test methods that provide repeatable measures of robotic system mobility and remote operator proficiency. The variable diagonal rail obstacle challenges robotic system locomotion, suspension systems to maintain traction, rollover tendencies, high-centering tendencies, self-righting (if necessary), chassis shape variability (if available), and remote situational awareness by the operator. As such, the variable diagonal rail obstacle can be used to represent obstacles in the environment, such as railroad tracks, curbs, and debris.
5.2 The scale of the apparatus can vary to provide different constraints representative of typical obstacle spacing in the intended deployment environment. For example, the three configurations can be representative of repeatable complexity for unobstructed obstacles (open configuration), relatively open parking lots with spaces between cars (rectangular confinement configuration), or within bus, train, or plane aisles, or dwellings with hallways and doorways (square confinement configuration).
5.3 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 and dates to determine best-in-class systems and operators.
5.4 Evaluation—This test method can be used in a controlled environment to measure baseline capabilities. The variable diagonal rail obstacle can also be embedded into operational training scenarios to measure degradation due to uncontrolled variables in lighting, weather, radio communications, GPS accuracy, etc.
5.5 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.
5.6 Training—This test method can be used to...
SCOPE
1.1 This test method is intended for remotely operated ground robots operating in complex, unstructured, and often hazardous environments. It specifies the apparatuses, procedures, and performance metrics necessary to measure the capability of a robot to negotiate an obstacle in the form of variable diagonal rail. This test method is one of several related mobility tests that can be used to evaluate overall system capabilities.
1.2 The robotic system includes a remote operator in control of most functionality, so an onboard camera and remote operator display are typically required. This test method can be used to evaluate assistive or autonomous behaviors intended to improve the effectiveness or efficiency of remotely operated systems.
1.3 Different user communities can set their own thresholds of acceptable performance within this test method for 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 Units—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 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 w...

INTRODUCTION
Theroboticscommunityneedswaystomeasurewhetheraparticularrobotiscapableofperforming
specific missions in complex, unstructured, and often hazardous, environments. These missions
require various combinations of elemental robot capabilities. Each capability can be represented as a
test method with an associated apparatus to provide tangible challenges for various mission
requirements and performance metrics to communicate results. These test methods can then be
combined and sequenced to evaluate essential robot capabilities and remote operator proficiencies
necessary to successfully perform intended missions.
TheASTM International Standards Committee on Homeland SecurityApplications (E54) specifies
these standard test methods to facilitate comparisons across different testing locations and dates for
diverse robot sizes and configurations.These standards support robot researchers, manufacturers, and
user organizations in different ways. Researchers use the standards to understand mission
requirements, encourage innovation, and demonstrate break-through capabilities. Manufacturers use
the standards to evaluate design decisions, integrate emerging technologies, and harden systems.
Emergency responders and soldiers use them to guide purchasing decisions, align deployment
expectations, and focus training with standard measures of operator proficiency. Associated usage
guides describe how these standards can be applied to support various objectives.
Several suites of standards address these elemental capabilities including maneuvering, mobility,
dexterity, sensing, energy, communications, durability, proficiency, autonomy, and logistics. This
standard is part of the Mobility suite of test methods.
