Abstract:
1. An anti-twist joint comprising: a base; a rotating member rotatably mounted to the base such that the rotating member rotates about a first axis; a pivoting member pivotably mounted to the rotating member such that the pivoting member pivots about a second axis; an anti-twist member rotatably mounted to the pivoting member; a coupling apparatus having one or more features on the anti-twist member that contact one or more features on the base to rotationally couple the anti-twist member to the base such that the rotational orientation of the anti-twist member relative to the base remains constant regardless of a rotational orientation or a pivoting orientation of the pivoting member relative to the base; and a pivot actuator coupled between the pivoting member and the rotating member to control a pivot angle therebetween.
