Abstract: A method of controlling an operator display arranged to display a model of an object being processed by a manually operated tool is provided. The displayed model is part of an operator instruction of how to process the object using the tool. The method comprises determining a position of the tool in relation to the object; and, based on the determined position of the tool in relation to the object, automatically selecting a viewing direction of the model of the object to be displayed on the operator display. The operator may then not have to manually select a picture/viewing angle of the model. Instead, the selection is made automatically depending on where the operator holding the tool is located in relation to the object. Hence, usage of the operator instructions is facilitated for the operator and time consuming manual handing can be reduced.

Abstract: A system comprising: an industrial robot comprising a robot arm end portion and a power supply circuit arranged to supply current to the robot arm end portion, and an end effector comprising a power tool and an accumulator module (such as a battery) arranged to power operation of the power tool, the end effector being attached to the robot arm end portion, the end effector further comprising a charger arranged to draw current from the power supply circuit at the robot arm end portion and to supply charging current to the accumulator module. Charging of the accumulator module for the power tool is facilitated and the efficiency of the manufacturing process is increased.
