Abstract

A portable articulated arm coordinate measuring machine is provided having a base. A cover is rotatably coupled to the base to move between a closed position and an open position. A display is arranged within the cover. The display includes a screen surface, such as a touch sensitive screen surface, disposed on one side of the housing. The screen surface being adjacent the base in the closed position and disposed on an angle to the base in the open position.

Claims

1. A method for operating a portable articulated arm coordinate measuring machine (AACMM) as a standalone measurement device, with steps comprising:

providing a base;

providing a manually positionable articulated arm having opposed first and second ends, the arm being rotationally coupled to the base on the second end, the arm including a plurality of connected arm segments, each arm segment including at least one position transducer for producing a position signal;

providing a measurement device attached to the first end;

providing an electronic circuit disposed internal to the AACMM having a processor and memory configured to execute a computer program, the electronic circuit configured to receive the position signals from the transducers and determine a position of the measurement device;

providing a display directly attached to the base and electrically coupled to the electronic circuit, the display having a programmable user interface;

providing the computer program having computer-readable program code resident in the memory, which when executed by the processor causes the electronic circuit, display, and user interface to operate the AACMM as a standalone measurement device;

attaching the base to a stationary object;

executing the computer program;

entering a first instruction by an operator using the user interface;

moving the measurement device to a first position by the operator;

measuring one or more coordinates of the first position; and

displaying the first position coordinates on the display.

2. A method for operating a portable articulated arm coordinate measuring machine (AACMM) as a standalone measurement device, with steps comprising:

providing a base;

providing a manually positionable articulated arm having opposed first and second ends, the arm being rotationally coupled to the base on the second end, the arm including a plurality of connected arm segments, each arm segment including at least one position transducer for producing a position signal;

providing a measurement device attached to the first end;

providing an electronic circuit housed internal to the AACMM having a processor and memory configured to execute a computer program, the electronic circuit configured to receive the position signals from the transducers and determine a position of the measurement device;

providing a display attached to the base and electrically coupled to the electronic circuit, the display having a programmable user interface which is responsive to a touch from an operator;

providing the computer program having computer-readable program code resident in the memory, which when executed by the processor causes the electronic circuit, display, and user interface to operate the AACMM;

executing the computer program;

entering a first instruction with the user interface;

moving the measurement device to a first position;

measuring one or more coordinates of the first position; and

displaying the first position coordinates on the display.

3. The method of claim 2 further comprising moving the display from a closed position to an open position prior to entering the first instruction.

4. The method of claim 2 further comprising providing a port electrically coupled to the electronic circuit adjacent the display and coupling an external device to the port.

5. The method of claim 4 wherein the external device is selected from a group comprising:

a bar code scanner, a digital camera, a digital video camera, a keyboard, a mouse, a printer and a cellular device.

6. The method of claim 2 wherein:

the plurality of connected arm segments are configured to define a path of travel for the measurement device; and

the display is separated from the path of travel by a gap.

7. The method of claim 6 wherein the step of moving the measurement device is a movement along the path of travel.

8. A method for operating a portable articulated arm coordinate measuring machine (AACMM) as a standalone measurement device, with steps comprising:

providing a base;

providing a manually positionable articulated arm having opposed first and second ends, the arm being rotationally coupled to the base on the second end, the arm including a plurality of connected arm segments, each arm segment including at least one position transducer for producing a position signal;

providing a first measurement device configured to be attached to the first end;

providing an electronic circuit arranged internal to the AACMM having a processor and memory configured to execute a computer program, the electronic circuit configured to receive the position signals from the transducers and determine a position of a plurality of measurement devices;

providing a display affixed to the base and electrically coupled to the electronic circuit, the display having a programmable user interface;

providing the computer program having computer-readable program code resident in the memory, which when executed by the processor causes the electronic circuit, display, and user interface to operate the AACMM, the computer program configured to;

display the programmable user interface on the display;

receive a first instruction from an operator via the programmable user interface;

process the first instruction;

receive the position signals from the transducers and determining the first position in response to the measurement device being moved; and

display the first position coordinates on the display in response at least in part on the first instruction.

9. The method of claim 8 further comprising:

providing a second measurement device configured to be attached to the first end;

detaching the first measurement device from the first end;

attaching the second measurement device to the first end;

wherein the computer program is further configured to;

receive a second instruction from the operator via the programmable user interface;

receive the position signals from the transducers and determining a second position in response to movement of the second measurement device; and

displaying the second position coordinates on the display in response at least in part on the second instruction.

10. The method of claim 9 further comprising moving the display from a closed position to an open position prior to entering the first instruction.

11. The method of claim 10 wherein in the step of providing the manually positionable articulated arm, the plurality of arm segments are configured to limit motions of the first measurement device to a first volume, and wherein in the step of providing the display, the display is configured to be outside the first volume.

12. The method of claim 8 wherein in the step of providing the display, the display is a touch sensitive display.

13. The method of claim 8 further comprising:

rotating the display by the operator from the open position to a first position, the open position being between the first position and the closed position.

14. The method of claim 8 further comprising providing a battery electrically coupled to the electronic circuit, and operating the portable articulated arm coordinate measuring machine solely on the battery.
