An industrial robot (10) comprises a base (20) configured to be stationary, a carousel (30) rotatable in relation to the base (20) about a first axis (210), a lower arm (40) rotatable in relation to the carousel (30) about a second axis (80), and an upper arm (50) rotatable in relation to the lower arm (40) about a third axis (140). The lower arm (40) comprises a first branch (220) and a second branch (230). There are a first bearing arrangement (120) between the carousel (30) and the first branch (220), a second bearing arrangement (180) between the first branch (220) and the upper arm (50), a third bearing arrangement (240) between the carousel (30) and the second branch (230), and a fourth bearing arrangement (250) between the second branch (230) and the upper arm (50). The robot (10) is configured to be fully functional in absence of the second branch (230), although the precision of the robot is improved when the second branch (230) is present. The second branch (230) is thereby optional, and the precision of the robot (10) can be improved when necessary while keeping existing bearing arrangements of the robot (10) intact.

A method for analysing a power electronics module (10) based on acoustic emissions comprises: generating a current pulse (38) through the power electronics module (10); receiving an acoustic signal (v(t)) from an acoustic sensor (28) adapted for acquiring acoustic emissions from the power electronics module (10); determining at least one characteristic value (50, 52) from the acoustic signal (v(t)), wherein the characteristic value (50, 52) is based on the acoustic signal acquired at different time points during and/or after the current pulse (38); and determining, whether the power electronics module (10) is fatigued, by comparing the at least one characteristic value (50, 52) with a threshold value (54, 56).


A monitoring arrangement (5) for monitoring a surge arrester (3) which is connected to a live wire (1) of a power network at a connection point (P2) in order to protect an electrical apparatus (2) against incoming surges, the monitoring arrangement comprising:- an analogue measuring circuit (25, 26) for sensing a current impulse through the surge arrester caused by an incoming surge in the live wire and producing a corresponding analogue measuring signal;- an analog-to-digital converter (42) for converting said measuring signal into digital signals; and- an electronic processing device (43) configured: to establish, based on said digital signals, a voltage peak value representing the highest voltage at said connection point during the incoming surge; and to establish, based on said voltage peak value and by means of a calculation model or look-up table, a maximum-voltage value representing an estimated maximum voltage across the electrical apparatus during the incoming surge.


A system and method for operating at least one stowable automated robotic pod in a workplace having a workpiece is disclosed. The pod includes a robot on a base that can also include one or both of a tool nest and process equipment. A door to subfloor storage allows the pod to raise its base vertical, placing the robot into the desired vertical position in the workspace. Once operations on the workpiece are complete, the pod withdraws back to the subfloor storage and the doors to the storage volume close.
