The device may be used for any lift or lifts, but is especially suited to powerlifting movements such as squat, bench press, and deadlift.

Abstract: The present invention recites a scissor arm for an unmanned robotic system such as a UAV, also known as a drone. This arm would typically be installed on the underside of a UAV with hover capability. The arm is designed to simultaneously vertically lower and horizontally extend a payload, permitting a person to interact with the payload without risk of injury by the UAV's propellers. This arm is practical for applications such as a routine police traffic stop, wherein an officer can safely remain in their vehicle and interact with the driver via a drone equipped with communication equipment and such an arm. The drone's arm can present the driver with a box for gathering documents from the driver without risk of injuring the driver or damaging the driver's vehicle. This is accomplished by two inventive “L”-shaped trusses that offset the arm's payload horizontally as the arm is extended downward.
