1、Designation: E2804 11Standard Test Method forEvaluating Emergency Response Robot Capabilities:Mobility: Confined Area Obstacles: Stairs/Landings1This standard is issued under the fixed designation E2804; the number immediately following the designation indicates the year oforiginal adoption or, in t
2、he case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 Purpose:1.1.1 The purpose of this test method is to quantitativelyevaluate a teleoper
3、ated ground robots (see TerminologyE2521) capability of traversing stairs with landings in confinedareas.1.1.2 Robots shall possess a certain set of mobility capabili-ties, including negotiating obstacles, to suit critical operationssuch as emergency responses. Stairs with landings are a type ofobst
4、acle that exists in emergency response and other environ-ments. These environments often pose constraints to roboticmobility to various degrees. This test method specifies appa-ratuses, procedures, and metrics to standardize this testing.1.1.3 The test apparatuses are scalable to provide a range ofl
5、ateral dimensions to constrain the robotic mobility during taskperformance. Fig. 1 shows three apparatus sizes to test robotsintended for different emergency response scenarios.1.1.4 Emergency response ground robots shall be able tohandle many types of obstacles and terrain complexities. Therequired
6、 mobility capabilities include traversing gaps, hurdles,stairs, slopes, various types of floor surfaces or terrains, andconfined passageways. Yet additional mobility requirementsinclude sustained speeds and towing capabilities. Standard testmethods are required to evaluate whether candidate robotsme
7、et these requirements.1.1.5 ASTM Task Group E54.08.01 on Robotics specifies amobility test suite, which consists of a set of test methods forevaluating these mobility capability requirements. This con-fined area stairs/landings test method is a part of the mobilitytest suite. The apparatuses associa
8、ted with the test methodschallenge specific robot capabilities in repeatable ways tofacilitate comparison of different robot models as well asparticular configurations of similar robot models.1.1.6 The mobility test suite quantifies elemental mobilitycapabilities necessary for ground robot intended
9、for emergencyresponse applications. As such, users of this standard can useeither the entire suite or a subset based on their particularperformance requirements. Users are also allowed to weightparticular test methods or particular metrics within a testmethod differently based on their specific perf
10、ormance require-ments. The testing results should collectively represent anemergency response ground robots overall mobility perfor-mance. These performance data can be used to guide procure-ment specifications and acceptance testing for robots intendedfor emergency response applications.NOTE 1Addit
11、ional test methods within the suite are anticipated to bedeveloped to address additional or advanced robotic mobility capabilityrequirements, including newly identified requirements and even for newapplication domains.1.2 Performing LocationThis test method shall be per-formed in a testing laborator

The values given in parentheses are not precisemathematical conversions to inch-pound units. They are closeapproximate equivalents for the pur

It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2

It is designed to serve asan extension of the operator for gaining improved remotesituational awareness and for projecting her/his intent throughthe equipped capabilities. It is designed to reduce risk to theoperator while improving effectiveness and efficiency of themissio

42、est Method4.1 The task for this test method, stair traversing, is definedas the entire robot traversing from the starting flat-floor terrainelement to the landing at the top of the stairs apparatus andback. See Fig. 1 for an illustration. The test starts at the set ofstairs with the lowest slope and
43、 having dry surface. As theevaluation proceeds, the task shall be performed on all theother stair surfaces and on the increased stair inclines asspecified in Section 6.4.2 The robots stair traversing capability is defined as thesteepest stair set that the robot is able to traverse for all theselecte
44、d surface types. Further, the test sponsor can specify thestatistical reliability and confidence levels of such a capabilityand, thus, dictate the number of successful task performancerepetitions that is required.4.3 Teleoperation shall be used from the operator stationspecified by the administrator
45、 to test the robots using an OCUprovided by the operator. The operator station shall be posi-tioned and implemented in such a manner so as to insulate theoperator from the sights and sounds generated at the testapparatus.4.4 The operator is allowed to practice before the test.She/he is also allowed
46、to abstain from the test before it isstarted. Once the test begins, there shall be no verbal commu-nication between the operator and the administrator regardingthe performance of a test repetition other than instructions onwhen to start and notifications of faults and any safety relatedconditions. T
47、he operator shall have the full responsibility todetermine whether and when the robot has completed arepetition and notify the administrator accordingly. However, itis the administrators authority to judge the completeness of therepetition.NOTE 2Practice within the test apparatus could help establis
48、h theapplicability of the robot for the given test method. It allows the operatorto gain familiarity with the standard apparatus and environmental condi-tions. It also helps the test administrator to establish the initial apparatussetting for the test when applicable.4.5 The test sponsor has the aut
49、hority to select the size ofthe lateral clearance for the specified confined area apparatus.The test sponsor also has the authority to select the testmethods that constitute the test event, to select one or more testsite(s) at which the test methods are implemented, to determinethe corresponding statistical reliability and confidence levels ofthe results for each of the test methods, and to establish theparticipation rules including the testing schedules and the testenvironmental conditions.5.
