5. April 21, 2006 PRE-DECISIONAL DRAFT: For Planning and Discussion Purposes Only 5 Past Period Accomplishments Jan 12, 2005 to Apr 13, 2005 Deliver final version of GESTALT navigator w/ ROAMS for LT validation Prepare delivery of tracking with Navigation to Hazard camera hand-off Complete sun sensor error model Complete generalized version of DriveMaps Navigator Continue prototyping of mechanism model Re-film the end-to-end single cycle instrument placement Continue repository clean-up and documentation Complete FIDO-2 stack battery discharge test Complete Delivery is on schedule Complete Work ongoing - was postponed to fix identified bugs in Morphin navigator Work ongoing - new mechanism model infrastructure developed SCIP now working on Rocky 8 Continuing - large number of improvements made Complete

6. April 21, 2006 PRE-DECISIONAL DRAFT: For Planning and Discussion Purposes Only 6 Significant Event � MER Navigation in CLARAty/ROAMS Delivered to MSL Long Range Validation Task MER navigation (GESTALT) integrated with CLARAty and ROAMS simulation GESTALT navigation provides: Rover capabilities for obstacle detection, obstacle avoidance, and navigation A local traversability map of surrounding terrain Technology maturation of MER navigation � integration of GESTALT with CLARAty Enables deployment on JPL research rovers Enables deployment with ROAMS high-fidelity simulation Enables component-level validation Importance: Navigation is necessary for long-range traverses Integration with CLARAty enables comparison against other algorithms Integration with ROAMS enables controlled experiments with varying pose estimates and terrain difficulty Integration and validation mature algorithm for MSL infusion.

7. April 21, 2006 PRE-DECISIONAL DRAFT: For Planning and Discussion Purposes Only 7 Technical Status (1/4) General Refactored r8_rover module to allow use with both Rocky 8 hardware and ROAMS simulation. (Shu) Eliminates code duplication and allows all CLARAty Rocky 8 users (sim and hardware) to leverage most recent R8 software updates and fixes Work being performed in cooperation with RoverWare Task (Norris) Continued debugging single-cycle instrument placement. (Kim, Simmons) Identified problems in Morphin. Provided navigation data sets to CMU. CMU is in process of fixing identified problems. Current fixes incorporated into SCIP demo SCIP is now operational on Rocky 8 and ready to refilm Met with International Affairs and obtained agreement that CLARAty could keep its current ITAR process of clearing people (vs. adopting new ISIS ITAR process of clearing documents and websites) Supporting new NRA work from MIT, Stanford, CMU, and Ames Started to define how K10 rover will use CLARAty CLARAty website can now be accessed with password from outside (vs. supplying machine IP address)

8. April 21, 2006 PRE-DECISIONAL DRAFT: For Planning and Discussion Purposes Only 8 Technical Status (2/4) Development Process Updated CLARAty code development process based on team feedback Distributed to team new policy for CLARAty naming conventions and coding standards. Developed and began regular use of autobuild system (Sapir, Gaines) Build creates nighyly HTML report which includes builds for all targets, success/fail report, and build times Build working on large number of core modules. 121 of these now build cleanly for both x86 VxWorks and Linux Developed design and began implementation of regression testing plan Added support for unit testing and baseline testing in CLARAty make system on Linux platform (Gaines) Hooks in place for VxWorks support Vision Worked with IP validation task to extend delivery for camera panoramic tracking with hand-off to navigations cameras (Madison, Kim) Revised camera hand-off to hazard cameras Incorporated changes from IP validation task into delivery code Currently working on second delivery of navigation camera tracking with hand-off to hazard cameras (Madison) Worked with IP validation task to complete plan for second delivery Delivery currently on schedule Added documentation to CLARAty web site for Ames stereo (Kunz)

9. April 21, 2006 PRE-DECISIONAL DRAFT: For Planning and Discussion Purposes Only 9 Locomotion & Navigation Delivered the MER GESTALT Navigation flight code integrated in CLARAty and running with ROAMS (McHenry) MER 9.0 version of GESTALT (with current bug fixes) Delivery used latest version of ROAMS Working with LT validation task to help with delivery installation and use Adapted GESTALT parameter settings according to R8/ROAMS configuration Updated GESTALT FDD Identified several bugs in Morphin Navigator, including problems with viewer and goodness calculations. CMU has fixed a number of problems. Still working on a few remaining issues. (Simmons) Contract in place with CMU for generalizing Drivemaps to support all rovers and enable mix and match of navigation components (Simmons) Work in progress on generalizing Drivemaps modules Mechanisms and Manipulation Completed Mechanism Models Requirements document (Nesnas, Nayar, Kim) Feedback has been collected New mechanism model infrastructure (Nayar) Implemented capability for reading multiple XML model files to create a single Mechanism_Model Implemented unit test for Tree class Began implementation of thread-safe and re-entrant features using CLARAty semaphore class (Nayar) Technical Status (3/4)

10. April 21, 2006 PRE-DECISIONAL DRAFT: For Planning and Discussion Purposes Only 10 Rover Position Estimation Contract in place with Univ. of Minnesota for continuing work on 6DOF EKF pose estimator. Completed sun sensor error model for the 6DOF EKF pose estimator (Diaz-Calderon) Resolved numerical problems with sun sensor update function and deriving a measurement model for 6DOF EKF (Roumeliotis) Simulation and Visualization Enabled CLARAty to run with latest version of ROAMS (Shu) Support CMU for testing TEMPEST with CLARAty and ROAMS Test bed FIDO II Stack delivery (Guineau) Demonstrated to management FIDO II stack controlling 3 motors and acquiring frame rate images Delivered configuration information to Rover Maintenance task Will enable upgrade of FIDO avionics and deployment of CLARAty on new hardware Provided rover usage plan to Eric Baumgartner Installed new version of Perl into AFS Technical Status (4/4)

11. April 21, 2006 PRE-DECISIONAL DRAFT: For Planning and Discussion Purposes Only 11 Planned Accomplishments April 12, 2005 to July 13, 2005 Complete delivery of MER GESTALT Navigation on FIDO rover Complete tracking delivery with Navigation to Hazard camera hand-off Finish filming of integrated single-cycle instrument placement Implement forward kinematics for mechanism model Implement regression testing plan for VxWorks Continue clean up of estimation code, infrastructure classes, and timing classes. Continue repository clean-up and documentation Complete sun sensor update function for 6DOF EKF and refactor into CLARAty
