    Abstract: A flood-fill method for parallel implementation includes the steps of receiving an image including first elements having a flood fill source colour to be replaced with a flood fill target colour, and second elements not having the flood fill source colour; dividing the image according to a hierarchical space-partitioning scheme to form cells at a plurality of levels in the hierarchy; detecting the occupancy of each cell by second elements; for any cell having no occupancy by second elements, set a depth elevation value for child cells of that cell to be one greater than the value for that cell, indicating that the flood fill shall navigate levels towards a root cell by the depth elevation amount of a cell whilst only occupying nodes without any second elements, thereby reaching the largest parent cell which can be flood-filled; and filling the flood fill source colour of cells having no occupancy by second elements with the flood fill target colour, thereby modifying the received image.

    Abstract: A system for controlling a robotic device in an indoor environment includes: a receiving unit of a robotic device configured to wirelessly receive, from at least a portion of a mains power line, a modulated electromagnetic signal leaked by the mains power line, the mains power line carrying a modulated alternating current signal, a demodulator of the robotic device configured to demodulate the modulated electromagnetic signal and extract one or more data signals from the demodulated electromagnetic signal, a processor configured to generate control data based on the one or more data signals, and a control unit configured to control one or more actuators of a robotic device based on the control data; and a system includes: a processor configured to generate control data for controlling one or more actuators of a robotic device, and a modulator configured to modulate an alternating current signal of a mains power line using the generated control data to create a modulated alternating current signal, thereby causing the mains power line to leak a modulated electromagnetic signal comprising the control data that is wirelessly detectable by a controlled robotic device.

    Abstract: A charging apparatus for wireless charging of one or more robotic devices includes a power transmitting unit having a plurality of conducting wires each configured to carry a respective alternating current signal and to generate a time-varying magnetic flux when the conducting wire carries the alternating current signal, a processor configured to detect a presence or an absence of an induction coil of a robotic device within a predetermined distance of a conducting wire and to generate control data based on the result of the detection, and a control unit configured to control at least one of an amplitude and a frequency of each respective alternating current signal supplied to each of the conducting wires based on the control data, where the control unit is configured to increase at least one of an amplitude and a frequency of an alternating current signal supplied to a conducting wire in response to control data indicating the presence of the induction coil within the predetermined distance of the conducting wire.
