Abstract

NIST has developed an antenna range that uses coordinated industrial robotic systems for measuring milli-meter wave (mmWave) antenna patterns and gain. The Configurable Robotic milli-meter Antenna (CROMMA) facility employs a multi-axis articulated serial robotic arm to place probes accurately around a test article. The positional and temporal capabilities, shown by CROMMA, has become a springboard to develop two new robotic ranges for use primarily from 0.5-30 GHz. Both of these systems are based upon commercial coordinated kinematic systems with multiple degrees of freedom. The CROMMA facility has two offshoots. The first is the dual robotic-arm Large Antenna Positioning System (LAPS). It is designed to perform large volume scanning with an emphasis on Multiple-Input Multiple Output (MIMO) and Over-the-Air (OTA) testing. The second system employs a seven-axis robotic arm to perform communication testing of Single Input Single Output (SISO) systems and will be used to establish modulated and continuous-wave field references. We will discuss the advantages, limitations and techniques employed to use these commercial robotic systems for accurate time- sensitive positioning and coordination with communications measurement equipment.
