Robot arm accelerates laser inspection

Designed to hasten repetitive 3D inspection duties, Metris̵7; RCA combines the automation capability of a traditional Coordinate Measuring Machine (CMM) with the mobility and part accessibility of an articulated arm. 

The Robot CMM Arm combines a highly accurate internal seven axis articulated arm with an external skeleton driven by electric motors. This unique concept creates a measuring robot that drives a Metris MMD laser scanner along the programmed motion path.

Thanks to premium encoder technology and stiff carbon fibre axes, RCA intrinsically offers truly absolute measurement accuracy within an inspection volume of 4.2m diameter today, and with larger models to come later.

With seven degrees of freedom, the RCA has infinite options available to access any inspection location. The RCA is capable of accessing inner cavity locations of specimens, such as vehicle body shells.

Unlimited accessibility is a major leap forward compared to traditional CMMs that face difficulty reaching enclosed part surfaces. In addition, RCA supports continuous adaptation of scanner orientation in order to consequently maintain optimal scanning conditions.
