About
The Hollywood "H" DDM is designed and made for "destroying" the Hollywood Sign in Los Angeles, California. The designers of "H" from ME218 are kidnapped by DrEd, an evil man, to participate in his "Big Plan" to dominate the world. The designers are smart Stanford students and come up with a hidden back door system inside the "H" device to disarm the DDM. Two people are required to accomplish several tasks to SAVE Hollywood! You are the heroes of the world!

Tasks:
A Distributed Destruction Mechanism (DDM) should be designed and made by Team 9 forced by DrEd for "destroying" one of the landmark around the world. The device must be camouflaged to blend into the landscape and avoid detection. Team 9 has to design a back-door into the device to be able to disARM the device and thwart DrEd’s nefarious plan. DrEd wishes to take the world by surprise so the device will be networked to show its status on DrEd’s Giant Red Button of Destruction. The device needs to be attractive enough to inspire everyday people to become Heroes by disARMing the DDM. Because there is a hero deep inside each of us, the device must be able to be disARMed by common civilians (including children, 218 alumni, and random people off the street) who may know little of the technology involved. The design should be suitable and appropriate for viewing and use by a multitude of interested potential Heroes of all ages. |
Requirements & Matched Functionalities:
- The DDM will power up into an ARMed mode. Whenever the device is in this mode it should create a display to maximize Fear and Panic: -When in theARMed state, the device emits red light and waves a sparking bomb flag on the top of the "H" to spread DrEd's anger to the world.
- Team 9 knows that the attention span of the average Hero is very limited, so the average Hero should take approximately 45 seconds to interact with its DDM in order to disarm it. No one except Sean Connery’s James Bond should be able to complete the process in less than 30 seconds: -So the wire sequence will be limited to 2 colors to make sure average heroes can disarm the DDM in around 45 seconds.
- The DDM should include a creative display of the passage of time since the Heroes have started to disARM the device. 7-segment displays don’t count: -A blinking red light shows the passage of time with increasing rate of blinking every 10 seconds while a timer counts down for 60 seconds in disarming state.
- In order to avoid distracting the Heroes while they are disARMing the DDM, the display inspiring Fear and Panic should stop: -The device flashes the red-light as a timer and switches sparking bomb flag into a cutting bomb fuse flag.
- In true Evil Villain fashion, the DDM should re-ARM if not completely disARMed within 60 seconds: -The device will stop spreading fear for 60 seconds when it is in disarming state. Then it switches back to the armed state.
- To insure that DrEd does not discover your back-door, disARMing a DDM should include interactions with two users. It should be impossible for DrEd to disARM the device by himself: -The "H" device has two interfaces for the two heroes on its two sides and the heroes need to communicate with each other to disARM the device together. Specifically, side A requires Hero A to keep spinning the wheel to power the device in disarming state while the hero on side B is moving a rod. It is impossible to complete the disarming process by one person.
- To prevent discovery of your back-door while developing your device, the disARMing of the DDM should require coordinated interaction between the Heroes and disARMing should not progress without the active involvement of both Heroes: -Communication of the two heroes is required since neither of the two heroes have complete information about the disARMing sequence.
- DisARMing the DDM should involve at least 3 distinct user interactions. The Heroes are in it for the Glory so each Hero must participate in at least two of these interactions: -Hero A has two interactions and Hero B has two interactions. Total four user interactions are required.
- One Hero’s actions should affect the interactions with the other Hero: -The control rod from Hero B will control the laser on Hero A's side.
- The DDM should require large scale motion on the part of the Heroes for at least one of its interactions: -Heroes' large scale motion result from moving control rod, spinning wheel and firing the laser.
- When the Heroes succeed in disARMing the DDM, the DDM should provide an exciting audio and/or visual experience that will inspire Hope & Joy in the hearts of tourists everywhere: -The audio feedback to heroes has two distinct sounds to tell whether they successfully cut the right wire or missed their target.
- If DrEd ever discovers that a DDM has been disARMed, he will re-ARM it and seek out the team to take out his anger. To avoid this situation, your DDM should automatically re-ARM 30 seconds after it has been disARMed: -The device will be rearmed 30 seconds after it has been disarmed.
- The DDM should be usable without human instruction. Any static instructions must be only in pictorial form: -The pictorial instruction is on each side of "H" are easily found and understandable.
- The DDM must set external line to 5V to reflect ARMed state of the DDM: -The device has an individual wire to give out 5V while it is in armed state.
