1. A belt driven actuator module including:
a guide track; a carriage guided by the guide track for longitudinal movement along the guide track; and a belt having a portion thereof attached to the carriage, wherein the carriage has a first lateral support surface for supporting a first longitudinal section of the belt against lateral deflection in a first direction, wherein the belt has a second longitudinal section contiguous with the first longitudinal section, which second longitudinal section is longitudinally offset from the first lateral support surface and is laterally deflected relative to the first lateral support surface in the first direction to take up slack in the belt and/or tension the belt, wherein the carriage has a second lateral support surface longitudinally spaced apart from the first lateral support surface for supporting a third longitudinal section of the belt against lateral deflection in the first direction, and the second longitudinal section of the belt is disposed between the first and third longitudinal sections, wherein the first longitudinal section, the second longitudinal section, and the third longitudinal section are contiguous, wherein the carriage includes first and second clamps for clamping the first and third longitudinal sections of the belt to the first and second lateral support surfaces, respectively, and wherein the belt is held within the carriage such that the second longitudinal section remains laterally deflected relative to the first lateral support surface. |
