Industrial robot

An industrial robot, comprising:

• a manipulator comprising a plurality of moveable members;
• a control unit comprising means for automatically operating the manipulator and receiving means for wireless information;
• and
• a portable operating unit comprising sending means for wireless information, wherein said information is divided into time slots, each comprising a data package, wherein the receiving means comprises detecting means for detecting in a time part of a time slot the presence of said data package and calculating means for calculating the number of time parts having no presence of said data package following a time slot with presence of said data package, whereupon the control unit on presence of an enabling signal in the data package exercises a control command when a data package has been received within watch-time comprising a number of time parts just exceeding a full time slot.

A method for safe wireless control of an industrial robot comprising a manipulator, a control unit having means for automatically operating the manipulator and a portable operating unit, comprising the operation unit sending information to the control unit, wherein said information is divided in time slots, each containing a data package, the method comprising:

• dividing each time slot into time parts,
• determining the presence of a data package received by the control unit within each of said time part,
• calculating upon reception failure the number of time parts with no presence of said data package following a time slot with presence of said data package, and
• exercising the control of the manipulator upon reception of said data package within a watch-time comprising a number of time parts exceeding a full time slot.
