An example test system includes robotics configured to operate on devices at a first level of precision, and stages configured to operate at levels of precision that are less than the first level of precision. Each of the stages may include parallel paths that are configured to pass the devices between adjacent stages.

Automated test system employing robotics

An example test system includes a test carrier to hold devices for test; a device shuttle to transport the devices; and a robot to move the devices between the test carrier and the device shuttle. The device shuttle is configured to move, towards a stage of the test system containing the robot, a first device among the devices that has not been tested. The device shuttle is configured to move in a first dimension. The robot is configured to move the first device from the device shuttle to the test carrier. The robot is configured to move in a second dimension that is different from the first dimension.

Automated test system having orthogonal robots

An example test system includes: a test rack including test slots; first and second shuttles that are configured to move contemporaneously to transport devices towards and away from trays, with at least some of the devices having been tested and at least some of the devices to be tested; first and second robots that are configured to move contemporaneously to move the devices that have been tested from test sockets in test carriers to the first and second shuttles, and to move the devices to be tested from the first and second shuttles to the test sockets in test carriers; and first and second test arms that are configured to move contemporaneously to move the test carriers between the first and second robots and the test rack.
