The six axes of a robot correspond to its six independent rotational joints, which allow it to move with human-like dexterity. These are the base rotation, shoulder rotation, elbow rotation, wrist roll, wrist pitch, and wrist yaw. Each axis allows the robot to move in a specific direction, enabling it to reach around obstacles and perform complex tasks.  

IEC 60439, the standard for low-voltage switchgear and controlgear assemblies, was under restructuring from the last decade. The new series of IEC 61439 standards were published in January 2009. This standard has brought considerable clarity in technical interpretation. The new standard follows the philosophy of IEC 60947 series i.e. IEC 61439-1 is ‘General Rules’ standard to be referred to by subsidiary product parts of IEC 61439 series. (Refer Table 1) The IEC 60439 standards were ambiguous about how to assess compliance of partially type tested assemblies. As a result manufacturers and testing bodies often treated partially type-tested assemblies differently. One of the main features of IEC 61439-1 is that the discrimination between Type Tested Assemblies (TTA) and Partially Type Tested Assemblies (PTTA) has been eliminated by the verification approach. The three different but equivalent types of verification methods are introduced and these are; a) Verification by Testing. b) Verification by Calculation/ Measurement. c) Verification by Design rules. The requirements regarding short circuit performance, temperature rise, dielectric properties and rated diversity factor have been covered in more detail.
