Comparison of a single- and dual-arm collaborative robots used for precision assembly

The aim of these studies is to evaluate ABB YuMi collaborative robots in single- and dual-arm variants for precise assembly of a computer motherboard. The characteristics of the object intended for assembly and the RobotStudio environment are presented. The tool path, assembly times, accelerations and speeds of the robot arms were analyzed, as well as cost estimation and energy consumption. A multi-criteria comparative evaluation of collaborative robots can allow for their accurate selection in industrial applications. The presented simulation tests and analyzes can be used at the initial design stage of robotic cell for the assembly of selected components of the PC motherboard.
