<div class="SectionLevel2"> <p class="subsec1 cdone2"><span class="Head3 cdone">1.1</span> This test method is intended for remotely operated ground robots using radio communications to transmit real-time data between a robot and its remote operator interface. This test method measures the maximum line-of-sight radio communications distance at which a robot can maintain omnidirectional steering, speed control, precise stopping, visual acuity, and other functionality. This test method is one of several related radio communication tests that can be used to evaluate overall system capabilities.

</div> <div class="SectionLevel2"> <p class="subsec1 cdone2"><span class="Head3 cdone">1.2</span> A remote operator is 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.

Imperial Units) are used throughout this document. They are not mathematical conversions. Rather, they are approximate equivalents in each system of units to enable the 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.

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.
