Design, fabricate and test a device that will autonomously provide signals (visual, audio and/or others, creativity appreciated) as close as possible to two times following initiation. One signal shall be after 30 seconds. The second signal shall be at a time between 13 and 24 seconds, the exact time to be determined by the toss of a pair of dice only three minutes before initiation. The operation of the device must be visible throughout the “run”. The device shall weigh less than 10 pounds, the lighter the better for the Final Testing. The testing will take place on a table provided by the instructor. All materials are to be provided by the team. The “Testing” of the device will take place at normal class times in the normal classroom (although the Final Testing for the may take place in the Engineering Building Commons), Initial Testing on October 20th and Final Testing on November 8th and 10th. There is no restriction on the type of energy used, but there can be no external energy source, i.e., the energy source is part of the device. Designs using gravitational energy will be viewed more favorably than those using other forms of energy. If multiple forms of energy are used, the greater the proportion of gravitational energy used the better. Batteries are allowed. Devices that use “excessive” energy may be penalized. Safety is of utmost importance, both to the people constructing and operating the device, and to those observing its operation. “Unsafe” devices will be disqualified, and “safe” devices may be rated higher than those judged to be less safe. Teams must submit their devices immediately after the Final Testing for evaluation along with “brochures” describing and “selling” their devices. Both written extended abstracts and oral presentations are required. Further information on the constraints, goals and evaluation processes are given in this document. Totally Lost...any ideas? Thank you in advance for your help!
