This paper describes recent developments in the ROAMS physics-based simulator for planetary surface exploration rover vehicles. ROAMS includes models for various subsystems and components of the vehicle including its mechanical subsystem, sensors, on-board resources, on-board control software, the terrain environment and terrain/vehicle interactions. The(More)
Planetary space mission applications involving landers and surface exploration vehicles make extensive use of terrain models within their simulation testbeds. Such terrain models are large, complex and have a variety of attributes including topography, reflectivity, soil mechanics, and hazard information. Sources for the terrain models include planetary(More)
This paper presents a rover execution architecture for controlling multiple, cooperating rovers. The overall goal of this architecture is to coordinate multiple rovers in performing complex tasks for planetary science. This architecture integrates a number of systems and research efforts on single rovers and extends them for multiple rover operations.(More)
YaM is a software development framework with tools for facilitating the rapid development of software in a concurrent software development environment. YaM provides solutions for thorny development challenges associated with software reuse, managing multiple software configurations, developing of software product-lines, and multiple platform development and(More)
This paper describes the ongoing development of the Roams physics-based simulator for planetary surface exploration rover vehicles. Roams includes models for various subsystems and components of the robotic vehicle including its mechanical subsystem, an electrical subsystem, internal and external sensors, on-board resources, on-board control software, the(More)
The Science Operations On Planetary Surfaces (SOOPS) task was created with the goal of evaluating, developing and validating methods for increasing the productivity of science operations on planetary surfaces. The highly integrated spacecraft-instrument payload systems of planetary surface missions create operational constraints (e.g. power, data volume,(More)
Economic load dispatch (ELD) problem is very important part of the power system. The purpose of economic dispatch is to determine the generation of different units in a plant such that the total fuel cost is minimum and at the same time the total demand and losses at any instant must be equal to the total generation. Many traditional methods such as lambda(More)
