Standard Test Method for Evaluating Emergency Response Robot Capabilities: Mobility: Confined Area Obstacles: Stairs/Landings
SIGNIFICANCE AND USE
5.1 A main purpose of using robots in emergency response operations is to enhance the safety and effectiveness of emergency responders operating in hazardous or inaccessible environments. The testing results of the candidate robot shall describe, in a statistically significant way, how reliably the robot is able to negotiate various types of obstacles, including the specified one, and thus provide emergency responders sufficiently high levels of confidence to determine the applicability of the robot.
5.2 This test method addresses robot performance requirements expressed by emergency responders and representatives from other interested organizations. The performance data captured within this test method are indicative of the testing robot’s capabilities. Having available a roster of successfully tested robots with associated performance data to guide procurement and deployment decisions for emergency responders is consistent with the guideline of “Governments at all levels have a responsibility to develop detailed, robust, all-hazards response plans” as stated in National Response Framework.
5.3 The test apparatuses are scalable to constrain robot maneuverability during task performance for a range of robot sizes in confined areas associated with emergency response operations. Variants of the apparatus provide minimum lateral clearance of 2.4 m (8 ft) for robots expected to operate around environments such as cluttered city streets, parking lots, and building lobbies; minimum lateral clearance of 1.2 m (4 ft) for robots expected to operate in and around environments such as large buildings, stairwells, and urban sidewalks; minimum lateral clearance of 0.6 m (2 ft) for robots expected to operate within environments such as dwellings and work spaces, buses and airplanes, and semi-collapsed structures; minimum lateral clearance of less than 0.6 m (2 ft) with a minimum vertical clearance adjustable from 0.6 m (2 ft) to 10 cm (4 in) for robots expected to deploy th...
SCOPE
1.1 Purpose:
1.1.1 The purpose of this test method is to quantitatively evaluate a teleoperated ground robot’s (see Terminology E2521) capability of traversing stairs with landings in confined areas.
1.1.2 Robots shall possess a certain set of mobility capabilities, including negotiating obstacles, to suit critical operations such as emergency responses. Stairs with landings are a type of obstacle that exists in emergency response and other environments. These environments often pose constraints to robotic mobility to various degrees. This test method specifies apparatuses, procedures, and metrics to standardize this testing.
1.1.3 The test apparatuses are scalable to provide a range of lateral dimensions to constrain the robotic mobility during task performance. Fig. 1 shows three apparatus sizes to test robots intended for different emergency response scenarios.
FIG. 1 Mobility: Confined Area Obstacles: Stairs/Landings Apparatuses
1.1.4 Emergency response ground robots shall be able to handle many types of obstacles and terrain complexities. The required mobility capabilities include traversing gaps, hurdles, stairs, slopes, various types of floor surfaces or terrains, and confined passageways. Yet additional mobility requirements include sustained speeds and towing capabilities. Standard test methods are required to evaluate whether candidate robots meet these requirements.
1.1.5 ASTM Task Group E54.08.01 on Robotics specifies a mobility test suite, which consists of a set of test methods for evaluating these mobility capability requirements. This confined area stairs/landings test method is a part of the mobility test suite. The apparatuses associated with the test methods challenge specific robot capabilities in repeatable ways to facilitate comparison of different robot models as well as particular configurations of similar robot models.
1.1.6 The mobility test suite quantifies elemental mobil...
