Abstract: An adjustable zero voltage to high voltage power supply electrically receives a voltage source and electronically receives a control signal. The adjustable zero voltage to high voltage power supply includes a first modulator generator, which provides an adjustable voltage signal equivalent to the operating range of the first modulator generator. A second modulator generator receives the adjustable voltage signal and produces a modulated signal. An adjustable pulse width modulator transmits a clock signal to the second modulator generator to control a frequency of the adjustable voltage signal and cause the second modulator generator to produce a modulated signal. A plurality of integrated circuits is configured to receive a control signal and feedback a signal to the first modulator generator and the adjustable pulse width modulator to change from a fixed frequency to a variable increasing frequency.

Abstract: A robotic apparatus for traversing a selected area autonomously that senses orientation relative to the Earth's magnetic field. The robotic apparatus is provided in two models, a master that can record directive and compass readings to provide at least one command recorded on a machine-readable medium representing an instruction for traversing an area of interest, and a slave that lacks the recording capability. Both master and slave models can replay recorded commands, and compare the expected orientation from the command with an actual orientation sensed during autonomous operation. If an error exceeding a predetermined value is observed, a corrective action is taken. The robotic apparatus is able to utilize a tool to perform a task at one or more locations, such as cutting, shoveling and digging. In one embodiment, the robotic apparatus is a lawn mower.
