The article discusses how economical misalignment-compensation techniques prevent bearing overload and premature gantry failure. Topics mentioned include the accepted notion that misalignment leads to problems, basic information about misalignment, and how a misalignment compensator works. It also reviews two misalignment-compensator designs including a compounded revolute joint for a 3D gantry configuration and an integrated revolute joint for a 2D gantry configuration.

The article discusses configurable products that can be used in linear-motion-guided gantry configurations for factory-floor automation instead of multi-axis robots. Topics covered include basic gantry concepts such as low to medium precision and heavy duty Z-axis, factors to consider when designing automated machinery, and custom design configurations. Also mentioned are gantry alternatives such as the cantilever axis, ballscrew actuator, and heavy-duty compact ballscrew system.

The article discusses the expansion of the scope of non-contact ultrasound imaging by improved transducers and inexpensive high-accuracy gantries. The features and capabilities of ultrasound imagers from SecondWave Systems are described. Information is presented on the typical uses for non-contact ultrasound imaging.
