© 2006 Carnegie Mellon Robotics Academy Designed for use with the LEGO MINDSTORMS ® Education NXT Software and Base Set #9797 Security Guards What do guards do? Protect important assets Enforce policy Monitor for suspicious or dangerous activity Handle on-site emergencies –Alert police, fire, or medical authorities if a situation arises –Security guards are generally not authorized to make arrests or administer complex medical aid without additional training or certification/authorization Night Watch Private security personnel are often responsible for keeping facilities and property safe at night

© 2006 Carnegie Mellon Robotics Academy Designed for use with the LEGO MINDSTORMS ® Education NXT Software and Base Set #9797 Security Guards Well-trained security personnel command a fairly high wage It can take many guards to watch a sizeable facility The day-to-day work of a security guard can be very repetitive and boring Security Room Even with several guards present, the amount of watching to do is huge, and potentially very monotonous Placeholder for: Security control room with many monitors

© 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
