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

© 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)

© 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)

© 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)

© 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)

© 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

© 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
