Abstract: An apparatus comprises a first electronic device module that comprises a structural stackable rack component that is attached to and supports an electronic device. A second electronic device module that comprises a stackable rack component that is attached to and supports an electronic device is stackable on and detachably coupled to the first electronic device module.

Abstract: A modular robotic welding station comprises a base skid to which is mounted robotic welding equipment. The base skid defines one or more docking stations. Satellite modules can have either stationary tables or turn tables that hold the workpieces to be welded. The satellite modules are detachably and interchangeably docked to selected base skid docking stations to thereby create customized workstations for the workpieces. The docking stations, satellite modules, and tables are designed to accurately locate the workpieces relative to the welding equipment. By detaching the satellite modules from the skid base, the satellite modules and skid base are easily transported individually from one location to another. A safety fence secured to the skid base can be arranged in different configurations to suit whether or not a satellite module is docked at a docking station.
