5. © 2006 Carnegie Mellon Robotics Academy Designed for use with the LEGO MINDSTORMS ® Education NXT Software and Base Set #9797 Mine Mapping What is mine mapping? –Going into old underground mines and creating maps of the tunnels Why would anyone want to map an abandoned mine? –See next page Mine Map Room-and-pillar tunnel structure appears gridlike in lower left

6. © 2006 Carnegie Mellon Robotics Academy Designed for use with the LEGO MINDSTORMS ® Education NXT Software and Base Set #9797 Mine Mapping Quecreek Mine Incident –Coal miners drilled into a flooded mine shaft from a different mine –The tunnel they drilled into was not documented by the original owner 100 years ago –Miners were barely rescued alive Quecreek Mine Entrance Nine men were trapped 240 feet below ground for 77 hours by rising toxic floodwaters.

Flooded Mine Iron residue mixes with water to create thick, acidic, orange mud. Many other hazards also hamper mine mapping operations.

9. © 2006 Carnegie Mellon Robotics Academy Designed for use with the LEGO MINDSTORMS ® Education NXT Software and Base Set #9797 Project Goal Design a robot that can gather data from an enclosed area Develop a procedure for interpreting the robot’s data to produce a usable map of the area Demonstrate and document your findings Final Demonstration The robot inside the box takes measurements while the operator interprets them to produce a map

10. © 2006 Carnegie Mellon Robotics Academy Designed for use with the LEGO MINDSTORMS ® Education NXT Software and Base Set #9797 Milestones Choose a design Submit a proposal Build a prototype Test and revise the prototype Demonstrate your robot

11. © 2006 Carnegie Mellon Robotics Academy Designed for use with the LEGO MINDSTORMS ® Education NXT Software and Base Set #9797 Engineering Process Research Phase └Choose a design Research the details of the problem in context Research different aspects of possible solutions Generate ideas for solution designs Evaluate and choose a design as a team (Internal Design Review)

12. © 2006 Carnegie Mellon Robotics Academy Designed for use with the LEGO MINDSTORMS ® Education NXT Software and Base Set #9797 Engineering Process Plan Phase └Submit a proposal Solidify a shared vision of the solution Identify the necessary tasks to complete development Schedule time for each task Assign responsibility for each task Organize your plan into a coherent proposal Submit proposal for approval (Project proposal)

13. © 2006 Carnegie Mellon Robotics Academy Designed for use with the LEGO MINDSTORMS ® Education NXT Software and Base Set #9797 Engineering Process Prototype Phase └Build a prototype Build and program the solution you proposed earlier Modify the design (only) when necessary Implement all the major functionality of the design Invite experts and supervisors to review the prototype (External design review)

14. © 2006 Carnegie Mellon Robotics Academy Designed for use with the LEGO MINDSTORMS ® Education NXT Software and Base Set #9797 Engineering Process Test Phase ├Test and revise the prototype └Demonstrate your robot Modify your design as requested by the reviewers Implement remaining functionality Test robot Revise design based on problems found during testing Repeat Test-Revise cycle Demonstrate working robot at agreed-upon time (Final demonstration)

15. © 2006 Carnegie Mellon Robotics Academy Designed for use with the LEGO MINDSTORMS ® Education NXT Software and Base Set #9797 Engineering Process Commercialize └Further improvements Examine the additional needs of the robot to be viable in the commercial marketplace Identify areas for improvement in design of robot Repeat development cycle to further improve the design

16. © 2006 Carnegie Mellon Robotics Academy Designed for use with the LEGO MINDSTORMS ® Education NXT Software and Base Set #9797 Unmapped mines pose a great danger to miners, even if they don’t work in those mines Mapping abandoned mines is highly impractical for human surveyors A robot surveyor could be the solution Summary Your robot proof-of-concept model must map a model mine shaft (box) You will use Engineering Process to guide your development Research Plan Prototype Test
