In an overhead line system, a first moving device is movable in the air between a first support post and a second support post. A first overhead line is stretched from the first moving device and connected to the first lifting device via the first support post. A second overhead line is stretched from the first moving device and connected to the second lifting device via the second support post. A second moving device is movable in the air between a third support post and a fourth support post. A third overhead line is stretched from the second moving device and connected to the third lifting device via the third support post. A fourth overhead line is stretched from the second moving device and connected to the fourth lifting device via the fourth support post. A suspension device is connected to the first moving device and the second moving device.

An aerial movement system and method for calibrating same includes, generally, registration points and wireless position transceivers proximate the registration points and the object that communicate with a computer and allow for the computer to determine the appropriate amount of support lines to draw in or release.

An aerial navigation system comprises four anchor points mounted on top of four upright members respectively at substantially same height from a ground, a carrier device coupled to a first set of four electric motors mounted at the four anchor points through a set of first wires. The set of first wires, the four upright members and the ground effectively define a volume. The carrier device is moveable in a bounded horizontal plane defined by the four anchor points. A robotic device is suspended from the carrier device using a second wire and moves vertically relative to the carrier device through activation of a fifth electric motor. A control unit is coupled to the first set of four electric motors and the fifth electric motor for controlling the three-dimensional movement of the robotic device to permit navigation from a current location to a target location inside the defined volume.

A navigation control system for an aerial robotic device suspended from a carrier device in an aerial movement volume of an aerial module. The navigation control system is configured to detect one or more stationary obstacles located in corresponding Aerial Movement Volume, create a 3D map representing the Aerial Movement Volume together with one or more bounding boxes enclosing each stationary obstacle in the Aerial Movement Volume, use an optimisation algorithm to compute an optimal route for the aerial robotic device, determine control parameters for a plurality of electric stepper motors driving the carrier device and the aerial robotic device based on the computed optimal route for the aerial robotic device, and navigate the aerial robotic device in accordance with the computed optimal route to enable the aerial robotic device to reach the required destination while avoiding intervening stationary obstacles.

In a cable-driven three-dimensional crane system, an end-effector is moved within an operating volume defined by dynamically shifting draw points. Winch assemblies pull the end-effector toward the respective draw points. Each winch assembly includes a cable router that manages travel of its drive cable through the associated draw point. Cable length encoders determine the effective length of each drive cable, from which one method of end-effector position calculations can be made. Draw point angle trackers assess the instantaneous lateral and vertical angles of each drive cable as it vectors away from its draw point toward the carrier from which another method of end-effector position calculations can be made as well as enabling self-calibration techniques. Sensitive mechanical and electrical components are sheltered in heated enclosures that wipe debris from the drive cable and track with its changing position. Multi-zone applications allow sharing of winch assemblies.
