Mechatronics Practice Test

With two actuators you get two independent motions along two perpendicular axes, defining a plane. A common two-actuator pick-and-place setup uses one actuator for horizontal travel (X) and another for vertical lift (Z). This lets the gripper reach objects along the horizontal direction and lift them up or down to place them at different heights, so the movement occurs in the XZ plane. Movement along the Y axis isn’t provided with this arrangement, which is why planes involving Y aren’t the typical two-actuator configuration.
