A robot wrist for the working hand of a robot has a connection element for connection to a robot arm along the main axis thereof, and a toolholder hinged to the connection element which has tool receiver axis and which can turn about a second axis normal to the main axis. One portion of the tool holder can pivot about a third axis parallel with the tool receiver axis and in the stretched position of the wrist in parallel with the main axis. The distances between the third axis and the tool receiver axis and between the third axis and the main axis are equal. |
