1、Designation: E2827 11Standard Test Method forEvaluating Emergency Response Robot Capabilities:Mobility: Confined Area Terrains: Crossing Pitch/RollRamps1This standard is issued under the fixed designation E2827; the number immediately following the designation indicates the year oforiginal adoption
2、or, in the 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, as a part of a suite ofmobilit
3、y test methods, is to quantitatively evaluate a teleoper-ated ground robots (see Terminology E2521) capability oftraversing complex terrain composed of crossing pitch/rollramps in confined areas.1.1.2 Robots shall possess a certain set of mobility capabili-ties, including negotiating complex terrain
4、s, to suit criticaloperations such as emergency responses. A part of the com-plexity is that the environments often pose constraints torobotic mobility to various degrees. This test method specifiesapparatuses to standardize a confined areas terrain that iscomposed of crossing pitch/roll ramps and t
5、hat notionallyrepresents types of terrains containing moderate discontinui-ties, existent in emergency response and other environments.This test method also specifies procedures and metrics tostandardize testing using the apparatus.1.1.3 The test apparatuses are scalable to provide a range oflateral
6、 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 ground robots shall be able to handlemany types of obstacles and terrains. The required mobilitycapabilities incl
7、ude traversing gaps, hurdles, stairs, slopes,various types of floor surfaces or terrains, and confinedpassageways. Yet additional mobility requirements includesustained speeds and towing capabilities. Standard test meth-ods are required to evaluate whether candidate robots meetthese requirements.1.1
8、.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 terrain with crossing pitch/roll ramps is a part of themobility test suite. Fig. 2 shows examples of other confin
9、edarea terrains, along with the traversing paths. The apparatusesassociated with the test methods challenge specific robotcapabilities in repeatable ways to facilitate comparison ofdifferent robot models as well as particular configurations ofsimilar robot models.1.1.6 The test methods quantify elem
10、ental mobility capa-bilities necessary for ground robots intended 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 me
11、trics within a testmethod differently based on their specific performance require-ments. The testing results should collectively represent anemergency response ground robots overall mobility perfor-mance as required. These performance data can be used toguide procurement specifications and acceptanc

24、ation.3.2.3.1 DiscussionA response robot is a deployable de-vice intended to perform operational tasks at operationaltempos during emergency responses. It is designed to serve asan extension of the operator for gaining improved remotesituational awareness and for projecting her/his intent throughthe
25、 equipped capabilities. It is designed to reduce risk to theoperator while improving effectiveness and efficiency of themission. The desired features of a response robot include: rapiddeployment; remote operation from an appropriate standoffdistance; mobility in complex environments; sufficient hard
26、en-ing against harsh environments; reliable and field serviceable;durable or cost effectively disposable, or both; and equippedwith operational safeguards.3.2.4 fault condition, nduring the performance of thetask(s) as specified by the test method, a certain condition mayoccur that renders the task
27、execution to be failed and such acondition is called a fault condition. Fault conditions result ina loss of credit for the partially completed repetition. The testtime continues until the operator determines that she/he can notcontinue and notifies the administrator. The administrator shall,then, pa

Summary of Test Method4.1 The task for this test method, crossing pitch/roll rampterrain traversing, is defined as the robot traversing from theSTART point along the specified path which ends back at theSTART point, thus enabling continuous repetitions. The defaultp

The START and END points are the same, locatedbeside the first pylon upon entering the gate. See Fig. 3 for anillustration.4.2 The robots traversing capability of this
48、 type of terrain isdefined as the robots ability to complete the task and theassociated effective speed. Further, the test sponsor can specifythe statistical reliability and confidence levels of such acapability and, thus, dictate the number of successful taskperformance repetitions that is required
49、. In such a case, theaverage effective speed shall be used, instead, as the robotscapability.4.3 Teleoperation shall be used from the operator stationspecified by the administrator 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 to abstain from the test before it isstarted.
