A single-handed hand held remote control for unmanned aerial vehicles (UAVs) is disclosed. The remote control includes a throttle control and a motion sensor(s) to detect various hand movements that can be mapped to various degrees of freedom. As the user moves the remote control, a micro-processor takes sampled data from the motion sensor(s) and determines a hand gesture which is used to identify a control instruction for the UAV. The control instruction is then transmitted via radio signal to the UAV to move the UAV accordingly. Some embodiments include a wrist member with its own motion sensor to improve on the movement sensing and provide enhanced control features.

1. A remote control system for an unmanned aerial vehicle (UAV), comprising a single-handed, hand held control housing;a push button throttle control in the control housing;a first motion sensor integrated into the hand held control housing;a radio transmitter in the hand held control housing;a micro-processor coupled to the push button throttle control, the radio transmitter, and the first motion sensor, wherein the micro-processor is configured to: detect a hand based movement by the first motion sensor;determine a type of the detected hand based movement;determine a mapped control instruction based on the determined type of hand based movement; andtransmit the mapped control instruction to the UAV through the radio transmitter; anda wrist member coupled to the hand held control housing, the wrist member further comprising a second motion sensor configured to detect motion of a user's arm, wherein the wrist member is electrically tethered to the hand held control housing and data from the first motion sensor and the second motion sensor are shared to the micro-processor for determining the mapped control instruction. 2. The remote control system of claim 1, wherein the push button throttle control is spring biased and wherein a length of travel in a spring of the push button control is used to determine throttle of the UAV. 3. The remote control system of claim 1, further comprising: a third motion sensor integrated into the wrist member, whereinthe second motion sensor and the third motion sensor are positioned axially symmetric around a wrist on which the wrist member is worn, the second motion sensor being attached to an outer surface of the wrist member and the third motion sensor being attached to an inner surface of the wrist member. 4. The remote control system of claim 3, wherein the detected hand based movement is one of radial/ulnar deviation, flexion/extension, and pronation/supination. 5. The remote control system of claim 4, wherein the radial/ulnar deviation, flexion/extension, and pronation/supination hand movements are each mapped to one of yaw, pitch, or roll control of the UAV. 6. The remote control system of claim 1, further comprising a gesture differentiator module configured to: calculate the relative space position of the user's hand to the user's arm, based on the estimated attitudes of the user's hand and the user's arm, anddetermine the UAV attitude based on the calculated relative space position of the user's hand to the user's arm, independent of the user's distance from the UAV. 7. The remote control system of claim 1, further comprising a module configured to: determine whether the single-handed, hand held control housing has been released from the user's grasp, andtransmit a signal to the UAV indicating a transition status for the UAV. 8. The remote control system of claim 1, further comprising a module configured to: determine whether the user's hand has returned to a default center position while grasping the single-handed, hand held control housing, andtrigger an alarm to the user based on the determination. 9. The remote control system of claim 1, further comprising a throttle rate detector module configured to: determine whether the throttle control of the single-handed, hand held control housing has been released from the user's grasp, andtransmit a signal to the UAV indicating a transition status for the UAV.
