ABSTRACT:
A manipulator apparatus for supporting and orienting the test head (11) of an automatic test equipment. A column assembly (14) has a sheath (26) which moves vertically and which is connected via a cable to a manually adjustable counterbalancing device (41) for supporting the weight of the test head (11). A ring (54) is mounted for rotation on the sheath (26) with a side portion (63) slidably receiving an arm (64). A block (81) is mounted for rotation about a vertical axis (theta-z) at the end of arm (64). Orienting means (16) are mounted in block (81) to rotate about a horizontal axis (theta-x), the test head having a radially extending arm (12) mounted for rotation about an additional axis (theta-y). Adjustment means are disposed between block (81) and orienting means (16) to prevent the head (11) from tilting about horizontal axis (theta-x).
