Robotic device tester
View Patent ↗A system, method, and device may include software and hardware which simplify and quicken configuration of the system for testing a device, enhance testing procedures which may be performed, and provide data via which to easily discern a cause and nature of an error which may result during testing. A camera may capture still images of a display screen of a tested device and another camera may capture video images of the tested device and a partner device. A wizard may be used to generate a configuration file based on one previously generated for a similar device. A mount for a tested device may be structured so that: it is suitable for mounting thereon a plurality of differently structured devices; and adjustments in a vertical direction and a horizontal direction in a plane and adjustments of an angle of the device relative to the plane may be easily made.
1. A system, comprising:
a first camera that has a first field of view and a first axis corresponding to the first field of view;
a second camera that has a second field of view and a second axis corresponding to the second field of view, wherein the second field of view is wider than the first field of view;
a memory storing expected testing results data;
a platform supporting a tested handheld-communication device and a partner communication device, wherein at least a portion of a display screen of the tested handheld-communication device is in the first field of view of the first camera, wherein the first axis is approximately perpendicular with the display screen of the tested handheld-communication device, and wherein the second axis is non-perpendicular with the display screen;
a robot arm to manipulate input hardware of the tested handheld-communication device; and
a processor configured to:
cause the robot arm to operate the tested handheld-communication device by manipulating the input hardware while the tested handheld-communication device is supported on the platform, wherein the manipulating the input hardware of the tested handheld-communication device causes the tested handheld-communication device to transmit a communication to the partner communication device;
receive first images taken by the first camera during operation of the tested handheld-communication device;
perform a comparison of the first images with the expected testing results;
determine, based on the comparison, whether an error has occurred; and
cause the memory to store second images, received from the second camera, of the tested handheld-communication device corresponding to a time period during which the error occurred.
2. The system of claim 1 , wherein the second field of view of the second camera includes all of the display screen of the tested handheld-communication device.
3. The system of claim 1 , wherein the display screen of the tested handheld-communication device is in better focus by the first camera compared with the second camera.
4. The system of claim 1 , the processor further configured to perform optical character recognition (OCR) of one or more images of the display screen of the tested handheld-communication device to make a determination that the error has occurred.
5. The system of claim 1 , wherein the tested handheld-communication device is positioned such that the display screen of the tested handheld-communication device is laterally shifted from the second axis extending through the lens of the second camera.
6. The system of claim 1 , wherein the processor is further configured to:
process at least one image received from at least one of the first camera or the second camera to identify a test sequence, and
cause the robot arm to operate the tested handheld-communication device according to the test sequence.
7. The system of claim 1 , wherein the processor is further configured to operate at least one light at a plurality of illumination levels during operation of at least one of the first camera and the second camera.
8. The system of claim 7 , wherein the processor is further configured to identify at least one of a position of the display screen or a perimeter of the display screen based on a contrast between light produced by the display screen and ambient light.
9. The system of claim 1 , wherein the system further comprises a compartment to enclose the tested handheld-communication device, the first camera, the second camera, the platform, and the robot arm.
10. The system of claim 1 , wherein the tested handheld-communication device is fixedly mounted to the platform such that the tested handheld-communication device is provided substantially in a same initial position for each test.
11. A non-transitory computer-readable medium having stored program instructions that, when executed, cause a processor to perform a method to test a first handheld-communication device, the method comprising operations of:
operating the first handheld-communication device and a second handheld-communication device according to a test sequence that causes communication between the first handheld-communication device and the second handheld-communication device;
capturing, using a first camera, first images of at least one of the first handheld-communication device;
capturing, using the second camera, second images of at least the first handheld-communication device and the second handheld-communication device, wherein a field of view of the second camera is greater than a field of view of the first camera;
comparing the first images with baseline images to make a determination that an error has occurred;
based on the determination that the error has occurred, storing at least a portion of the second images, the portion of the second images corresponding to a time period during which the error occurred;
wherein the first handheld-communication device is provided on a platform and a first axis extends through a lens of the first camera and approximately perpendicularly through the platform and a second axis extends through a lens of the second camera and non-perpendicularly through the platform.
12. The non-transitory computer-readable medium of claim 11 , wherein the method further comprises performing optical character recognition (OCR) of at least one of the first images or the second images.
13. The non-transitory computer-readable medium of claim 11 , wherein the first handheld-communication device is positioned such that a display screen of the first handheld-communication device is laterally shifted from the second axis extending through the lens of the second camera.
14. The non-transitory computer-readable medium of claim 11 , wherein the method further comprises:
processing at least one image received from at least one of the first camera or the second camera to identify a test sequence; and
causing a robot arm to operate the first handheld-communication device according to the test sequence.
15. The non-transitory computer-readable medium of claim 10 , wherein the method further comprises operating at least one light at a plurality of illumination levels during operation of at least one of the first camera and the second camera.
16. The non-transitory computer-readable medium of claim 15 , wherein the method further comprises identifying at least one of a position and a perimeter of a display screen of the first handheld-communication device based on a contrast between light produced by the display screen and ambient light.
17. The non-transitory computer-readable medium of claim 11 , wherein the first handheld-communication device is fixedly mounted to the platform such that the first handheld-communication device is provided substantially in a same initial position for each test.
