Teach pendant for an industrial robot

A control unit for use with a programmable industrial robot, the control unit comprising:

• a processing unit for receiving, processing, and outputting data;
• a body;
• a display screen mounted on the body and having a screen surface that is sensitive to movement of a pointing device over the screen surface, the display screen operable to present graphical information items, on which an operator may make selections of the items presented on the display screen, capable of producing a screen output, and coupled in data transmission relation to the processing unit;
• a joystick ball mounted on the body for controlling the robot during a programming phase during which the robot is taught to follow an operating path, the joystick ball having a joystick mounting means, for producing a joystick ball output, and coupled in data transmission relation to the processing unit;
• and
• a pointing device removably mounted to the joystick mounting means and for being used to make selections on the display screen.

A programmable industrial robot comprising

• a main body;
• a robot arm coupled to the main body;
• data input means coupled in data transmission relation to the programmable industrial robot;
• and
• a control unit including:
• a processing unit for receiving, processing, and outputting data, and coupled in data transmission relation to the data input means;
• a body;
• a display screen mounted on the body and having a screen surface sensitive to the movement of a pointing device over the screen surface, operable to present graphical information items, on which an operator may make selections of the items presented on the display screen, for producing a screen output, and coupled in data transmission relation to the processing unit;
• a joystick ball mounted on the body for controlling the robot during a programming phase during which the robot is taught to follow an operating path, the joystick ball having a joystick mounting means, for producing a joystick ball output, and coupled in data transmission relation to the processing unit;
• and
• a pointing device removably mounted to the joystick mounting means and for being used to make selections on the display screen.

A method of programming a programmable industrial robot, the robot having a an operating unit which includes:

• a body;
• a display screen having a screen surface and mounted on the body, operable to graphically display information items, on which an operator may make selections of the items presented on the display screen, and capable of producing a screen output;
• a joystick ball mounted on the body for controlling the robot during a programming phase during which the robot is taught to follow an operating path, the joystick ball having a joystick mounting means and capable of producing a joystick ball output;
• and a pointing device removably mounted to the joystick mounting means and capable of being used to make selections on the display screen;
• the method comprising the steps of:
• creating a mechanical input to the joystick ball by moving the pointing device, the mechanical input being converted into a processable data signal, in order to control the movement of the robot;
• and
• making selections on the display screen with the pointing device by removing the pointing device from the joystick ball and moving it over the screen surface.

An operating unit for a programmable industrial robot that is coupled in data communication to a processing unit, the operating unit comprising:

• a body;
• a display screen for being coupled in data communication to the processing unit, having a screen surface that is sensitive to movement of a pointing device over it, and mounted on the body, the display screen operable to graphically display information items, on which an operator may make selections of the items presented on the display screen, and to produce a screen output;
• a joystick ball mounted on the body and coupled in data communication to the processing unit, the joystick ball for producing a joystick ball output and controlling the robot during a programming phase during which the robot is taught to follow an operating path, the joystick ball having a joystick mounting means;
• a pointing device removably mounted to the joystick mounting means and for making selections on the display screen;
• and
• means for sensing whether the pointing device is mounted to the joystick mounting means;
• wherein the screen output, the joystick ball output, or both the screen output and joystick output are transmitted to the processing unit.

An operating unit for a programmable industrial robot that is coupled to a processing unit, the operating unit comprising:
