Abstract: Apparatus, methods, and systems for adjusting a center of mass of a drone may include a balance track and a repositionable weight. The balance track may be configured to extend outwardly from a central region of the drone. The balance track may include a plurality of weight-balance fixation positions. The repositionable weight may be configured to be secured at any one of the plurality of weight-balance fixation positions. In various embodiments the repositionable weight may include an electronic component. Various embodiments may include a another balance track configured to extend outwardly from the central region along a second axis that is different from a first axis of the other balance track.

Abstract: According to some embodiments, there is provided a tether system for coupling an unmanned aerial vehicle (UAV) to an anchor location, the tether system comprising a tether line configured to couple the UAV to the anchor location during flight of the UAV, and an anti-entanglement (AE) member extending along a section of the tether line, the AE member having a first end proximate the UAV and a second end opposite the first end, proximate the anchor location.

The balance track may extend outwardly from a central region of the drone. The balance track may include a plurality of weight-balance fixation positions. The repositionable weight may be configured to be secured at any one of the plurality of weight-balance fixation positions. Various embodiments may include receiving a weight-distribution input relating to balancing the drone. A weight-distribution balance profile may be determined, based on the weight-distribution input, for determining whether a repositionable weight should be repositioned among a plurality of weight-balance fixation positions on a balance track extending outwardly from a central region of the drone. The repositionable weight may be repositioned according to the weight-distribution balance profile.
