Yes they're plastic, no they aren't milk crates. They aren't new, either, they've been making Rams better for years.

This paper presents a novel learning control method for ball-screw-driven stages. In recent years, many types of friction models that are based on complicated equations have been studied. However, it ...

When pickleball exploded in recent years as America’s favorite sport, the pastime came with collateral damage — plastic neon-colored balls piling up in landfills. More than 500 million ...

Ball-screw-driven stages are widely used in industry for long-range and high-precision fabrication. One of the main difficulties in dealing with high-precision motion control is the nonlinear friction ...
