Also provided is a method for controlling the relative rotation between a UAV and a device, where the device is attached to said UAV via at least two cords, said method comprising the steps of: a. determining a reference rotational position of said device relative to said UAV, b. detecting an angular rotation R in a horizontal plane of said device relative to said reference position, c. compensating said angular rotation in said horizontal plane of said device by rotating said UAV in said horizontal plane in the same direction and by the same angular rotation R as said device for prohibiting twisting of said cords.

A remote-operated palm tree trimming system and apparatus, configured to ascend a palm tree safely via treaded tires and trim the tree via at least one saw blade. The tires are disposed in communication with actuators which apply pressure against the trunk of the tree, ensuring that the tires maintain adequate grip to overcome gravity during ascent. A remote control, operated by user on the ground, enables control of the wheels, actuators, and saw blade, facilitating manipulation of the device to effectively trim the tree remotely, ensuring the safety of the operator.

An airborne grapple saw system includes a suspension assembly, a hydraulic power pack assembly, and a grapple saw head assembly. The suspension assembly is configured to be suspended from an aerial vehicle. The hydraulic power pack assembly is operatively coupled with the suspension assembly. The grapple saw head assembly is operatively coupled with the hydraulic power pack assembly. The grapple saw head assembly is configured to freely rotate about a vertical axis an unlimited number of revolutions. The grapple saw head assembly includes a saw and first and second grapple arms. The grapple arms are pivotable between an open configuration, where the grapple arms are configured to obtain and release the vegetation, and a closed configuration, where the grapple arms are configured to securely retain the vegetation.
