Ground control of space station robotics systems, unmanned space platform servicing, earth-based control of lunar and planetary rover missions, and planetary balloon missions.
Planetary surface mobility has to date been limited to benign locations. If rover systems could be developed for more challenging terrain, e.g., sloped and irregularly feathered areas, then planetary science opportunities would be greatly expanded.
This paper describes recent work undertaken at the Jet Propulsion Laboratory in Pasadena, CA in the area of increased rover autonomy for planetary surface operations.
This chapter describes fundamental research aimed at achieving such long-term objectives through application of soft computing techniques for safe and reliable autonomous rover navigation.
This paper describes a dynamic planning system for coordinating multiple rovers in collecting planetary surface data.
Current rover designs use on-board manipulators to enhance their capabilities for planetary exploration and in-situ science. In this paper, we describe how these manipulators can be used to perform two types of operations: rock sample aquisition for return to earth and instrument placement for in-situ science meausrements.
Recently, significant advances have been made in enabling autonomous rovers and robotic vehicles.
In this paper, we describe how rover command generation can be automated to help relieve some of the burden on human operators.
In this paper we describe the Visual Odometry algorithm used on the Mars Exploration Rovers, and summarize the results obtained by running this processing onboard during the first year of operations on Mars.
The Imaging System on the Mars Exploration Rovers has successfully operated on the surface of Mars for over one Earth year. An overview of the surface imaging activities is provided, along with a summary of the image data acquired to date.
The Mars Exploration Rovers (MER) Flight Software (FSW) is possibly the most complex software implmentation to be deployed on another planet. This paper provides an overview of the function and structure of the MER flight software.
This paper describes recent efforts of the Mars Technology Program (MTP) to develop, integrate, and validate new rover technologies for upcoming missions.
This paper describes recent efforts of the Mars Technology Program (MTP) to develop, integrate, and validate new rover technologies for upcoming missions.
Key to the success of the rovers was the development of their advanced mobility system. In this paper the mobility assembly, the mechanical hardware that determines the vehicles mobility capability, is described.
In January of 2004, NASA landed two mobile robotic spacecraft on the surface of Mars as part of the Mars Exploration Rover (MER) project. The results and lessons learned of the test and dynamic simulation of the MER vehicles is provided in this paper.
This paper presents an introduction to the CLEAR system which performs rover command generation and re-planning, the challenges faced maintaining domain specific information in an uncertain environment, and the successes demonstrated with several methods of system testing.
This paper describes the design, implementation, and experimental results of an integrated system that enables Mars rover to navigate in a high slip environment.
This paper will discuss the system level verfication and validation test program for the surface capability of the Mars Exploration Rovers (MER).
