The Autonomy and Robotics Area (ARA) at NASA Ames Research Center has investigated the use of various types of Virtual Reality-based operator interfaces to remotely control complex robotic mechanisms. In this paper, we describe the major accomplishments and technology applications of the ARA in this area, and highlight the advantages and issues related to… (More)
Longitudinal study designs in biomedical research are motivated by the need or desire of a researcher to assess the change over time of an outcome and what risk factors may be associated with the outcome. The outcome is measured repeatedly over time for every individual in the study, and risk factors may be measured repeatedly over time or they may be… (More)
In Summer 2007, we field-tested a robotic survey system at Haughton Crater (Devon Island, Canada). Two NASA Ames K10 planetary rovers performed systematic surveys of several simulated lunar sites, including a roughly 700m x 700m region called Drill Hill. The rovers carried a 3D scanning lidar for topog-raphic mapping and ground penetrating radar to map… (More)
This paper describes the K9 rover operations at the Jet Propulsion Laboratory (JPL) during a dual-rover field experiment involving the NASA Ames Research Center's K9 rover and JPL's FIDO rover in May of 2000. We will describe the use of various ground tools used for sequence generation and the onboard conditional executive.
Since 2004, NASA has been working to return to the Moon. In contrast to the Apollo missions, two key objectives of the current exploration program are to establish surface infrastructure and an outpost. Achieving these objectives will enable long-duration stays and long-distance exploration of the Moon. To do this, robotic systems will be needed to perform… (More)
Modern NASA planetary exploration missions employ complex systems of hardware and software managed by large teams of engineers and scientists in order to study remote environments. The most complex and successful of these recent projects is the Mars Exploration Rover mission. The Computational Sciences Division at NASA Ames Research Center delivered a 3D… (More)
Simulation and visualization of rover behavior are critical capabilities for scientists and rover operators to construct, test, and validate plans for commanding a remote rover. The VIPER system links these capabilities , using a high-fidelity virtual-reality (VR) environment, a kinematically accurate simulator, and a flexible plan executive to allow users… (More)
In this paper, we describe NASA Ames Research Center's K10 rover as used in the 2006 Coordinated Field Demonstration at Meteor Crater, Arizona. We briefly discuss the control software architecture and describe a high dynamic range imaging system and panoramic display system used for the remote inspection of an EVA crew vehicle.
This paper introduces an advanced rover localization system suitable for autonomous planetary exploration in the absence of Global Positioning System (GPS) infrastructure. Given an existing terrain map (image and elevation) obtained from satellite imagery and the images provided by the rover stereo camera system, the proposed method determines the best… (More)
NASA is planning to send humans and robots back to the Moon before 2020. In order for extended missions to be productive, high quality maps of lunar terrain and resources are required. Although orbital images can provide much information, many features (local topography, resources, etc) will have to be characterized directly on the surface. To address this… (More)
