Tabletop robots, error-proof fastening tools and a manufacturing app for the Google Glass were among the myriad new technologies that dazzled manufacturing engineers and managers attending the second annual ASSEMBLY Show.

Some 205 technology suppliers—55 more than last year’s event—exhibited at the show, which was held Oct. 28-30 at the Donald E. Stephens Convention Center in Rosemont, IL. The exhibits spanned more than 50,000 net square feet, a 41 percent increase over 2013.
