Aerial navigation system

A method for operating an aerial navigation system to control aerial movement of a robotic device therein, the method comprising:

• providing a plurality of upright members supported by a ground surface and mounting top portions of the plurality of upright members with anchor points at a substantially same height from the ground surface;
• providing an electric motor and a first wire to each anchor point to operably support movement of a carrier device in a horizontal plane co-planar with the anchor points corresponding to the plurality of upright members;
• suspending the robotic device from the carrier device using a second wire such that the robotic device is moveable within a volume defined between the ground surface and the horizontal plane by at least one other electric motor of the carrier device;
• and
• synchronising operations of the electric motors at the anchor points and the carrier device to permit the robotic device to be moved from a current location to a target location within the volume.

A non-transitory computer readable medium having stored thereon computer-executable instructions which, when executed by a processor, cause the processor to:

• determine a current location of a robotic device within a volume;
• calculate a route between the current location of the robotic device and a target location based on depth related obstacle information output by a depth detecting sensor;
• compute parameters including a number of rotation steps (nrot), a direction of rotation (dir), and a speed of rotation (θ) for a plurality of electric motors provided at a plurality of anchor points on a plurality of upright support members and at least one other electric motor of a carrier device moveably connected to the electric motors provided at the plurality of anchor points;
• and
• move the robotic device from the current location to the target location within the volume by synchronising operations of the electric motors provided at the anchor points and the carrier device based, at least in part, on the depth related obstacle information and the computed parameters for each of the electric motors.
