This paper reports some of the ongoing work at JPL in the areas of autonomous sensory fusion of both raw and derived inputs for better localization during long traverses, precision rendezvous operations with both labeled and unlabeled targets, and precision manipulation of targets.
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 paper describes the development of a two-tier state estimation approach for NASA/JPL's FIDO Rover that utilizes wheel odometry, inertial measurement sensors, and a sun sensor to generate accurate estimates of the rover's position and attitude throughout a rover traverse.

We overview our recent research on planetary mobility.
We overview or recent development and testing of the FIDO rover, an advanced technology prototype for long range mobile planetary science.
While significant recent progress has been made in development of mobile robots for planetary suface exploration,there remain major challenges. These include increased autonomy of operation, traverse of challenging terrain, and fault-tolerance under long, unattended periods of use.
Results of May 2000 field testing of the FIDO prototype Mars rover are summarized. Tests included remote science operations and simulated aspects of the Athena payload for 2003 MER (Mars Exploration Rovers). Additional information is contained in the original extended abstract.
This paper describes the means for generating rover localization information for NASA/JPL's FIDO rover. This is accomplished using a sensor fusion framework which combines wheel odometry with sun sensor and intertial navigation sensors to provide an integrated state estimate for the vehicle's position and oreintation relative to some fixed reference frame.
This paper will describe a NASA/JPL rover system that has been focused on developing technologies required for the in-situ exploration of Mars. In particular, JPL has been developing a class of rovers that carrry significant payloads that address geological exploration and discovery along with the ability to acquire samples from soils and rocks.
The Mars 2003 Mission may include a rover to acquire remote sensing and in-situ measurements of surface materials, including rock surfaces that have been cleared of dust and coatings by use of an abrasion tool. Mars Sample Return Missions for 2005 and beyond may include rovers with remote sensing and in-situ measurement capabilities. Further, these mobility platforms may have systems to drill into rocks and collect cores, acquire soil samples, and place the rock and soil samples in ascent vehicles. The point of this abstract is to document that these operations have already been shown to be tractable based on continuing field trials of the FIDO Mars prototype rover.
An integrated team of students and teachers from four high schools across the country developed and implemented their own mission of exploration and discovery using the Mars Sample Return prototype rover, FIDO, at Silver Lake in the Mojave Desert.
During field trials in the Mojave Desert, the Mars Sample Return (MSR) prototype rover, FIDO, simulated sampling and exploration activities with a science payload similar to what will be on the MSR rover, validating the mission operations approach.
