Since specific safety standards for this robotic sector are not available, they should be carried out on the base of system safety engineering that is discussed here and especially on STAMP (Systems-Theoretic Accident Model and Processes). STAMP involves the relation between manufacturer, user and organization for standardization that results from safety standards with the respective safety requirements, interface from industrial safety to humanoid safety, effect of the use of accident analysis on safety standards. In this paper, we follow the steps of STAMP methodology in order to establish safety standardization’s requirements for humanoids. These results may serve as a supplement to the standards.

The scheme, which is based on smart sensors, allows users to create and run environmental conditions control scenarios to an entirely parameterized telemetry and telecontrol system. The core of the telemetry element is a wireless sensor network (WSN), which monitors the environmental condition of a controlled environment. The purpose of this WSN is to provide data for the successful automatic management of various devices and subsystems that can be used to regulate environmental conditions. The control system is complemented by an advanced user interface to provide manual override on automatic processes. This includes a data glove (a technology taken from virtual reality), which provides the user with the ability to feed override commands using finger gestures. Under normal (fully automated) operation, the environmental conditions are regulated automatically according to user scenarios. With the use of the override subsystem, the user overrides the automatic control of all subsystems having the possibility to stop the operation of any preferred subsystem online (in real-time).

The hybrid energy system combines regenerative fuel cells, photovoltaic generators and batteries. The proposed power conditioning topology, which can be implemented at low cost, can provide bi-directional power flow with high frequency ohmic isolation, thus providing regenerative and charging capabilities. The proposed topology presents a number of advantages: 1) provides bi-directional power flow to the system, permitting the use of regenerative fuel cells and/or batteries, 2) incorporates a high frequency power transformer, thus exhibiting high power density, 3) employs a low voltage battery configuration, eliminating the necessity of a battery management system, 4) draws low ripple current from the fuel cell stack at a low switching frequency, 5) provides fuel cell start-up and battery charging through the utility grid and/or any possible renewable energy converters and 6) exhibits unity input power factor when operating in grid connected mode. Analytical as well as simulation and experimental results are presented for the proposed topology.

The present approach utilizes the shift and product operational matrices of the Fourier series for the analysis of linear systems via the Fourier operational matrix of integration. The method developed is applied to the analysis of a number of illustrative model systems.
