1. A test module for testing mobile devices, the test module comprising:
a frame;
a test bed coupled to the frame;
a device platform coupled to the test bed and configured to hold a Device Under Test (DUT);
a motion system coupled to the frame and configured to move a carriage assembly horizontally along an X axis and a Y axis, the motion system comprising:
a first belt and a second belt;
a first set of pulleys and a second set of pulleys; and
a first motor and a second motor,
wherein the first belt is engaged with the first set of pulleys and the first motor, and
wherein the second belt is engaged with the second set of pulleys and the second motor;
an actuator arm coupled to the carriage assembly;
an actuator arm mount coupled to the actuator arm, the actuator arm mount configured to move vertically along a Z axis and engage the DUT; and
a controller configured to control the motion system and the actuator arm to perform various tests with respect to the DUT; and
a sliding drawer movably coupled to the frame below the test bed, the sliding drawer being configured to slide at least partially out from below the test bed,
wherein the sliding drawer is movable relative to the test bed, and
wherein the controller is mounted on the sliding drawer.
