Link to project 550_JK team page.

Give instructor top 3 project choice list

 * 1. Rubberband gun


 * 2. Rube Goldberg


 * 3. StrandBeest

Write problem statement

 * How can a gun be built with a trigger system that can fire sequentially (instead of reloading after each fire)?
 * How can each trigger system be integrated into the above mentioned gun?

Assign Task1

 * Research ways to auto load a rubber band after firing one.
 * Create new designs of a trigger system.
 * Think of ways to improve on the existing trigger systems.

Compare actual work done to Task1

 * Helped test the accuracy of the rifle
 * Added a second bridge to gattling gun
 * Created one side of the base for the gattling gun

Week1 Narrative
[| Video of Lego Gattling Gun Firing Rubbberbands]
 * Our team had decided to make a gattling gun similar to a video we found online
 * The accuracy of the rifle was tested by adding target lock on the gun to look through, the aim was off by less than a few inches each time when shooting from a distance of 15 feet
 * Within the first few days, a working prototype was built, capable of firing 8 rubber bands
 * A second base was made to allow double the firing of rubber bands, but only half a bridge has been made

Assign Task2

 * Get the second bridge of the gattling gun working to fire double the rubberbands
 * Improve on the structure to make it stronger
 * Improve on the accuracy of the rifle

Compare actual work done to Task3

 * Worked on improving both bases
 * Completed constructing both barrels
 * Added a handle to manually rotate the barrels
 * Ordered lego battery

Week3 Narrative
The base on the front end of the gun was removed and replaced by a bigger and sturdier base. The back base was made to mirror the front base in size and sturdiness, but a rotating handle was added temporarily to rotate the barrels. We tried different methods to get the gun to fire with the string trigger, but we were unsuccessful. The battery should arrive soon which would allow us to use the motor. We plan on attaching both strings to the motor and placing the motor in the center so when it spins, the string is winded up thus causing the barrels to spin and fire. We are also looking for an alternate way of firing the gun by getting rid of the string system and allowing a more manual way of firing using the handle.

Assign Task4

 * If battery arrives, work on implementing the motor
 * Improve on the string trigger, or change trigger completely
 * Finalize the Gatling rubber band gun

Compare actual work done to Task4
Rationalize differences

Week4 Narrative
Upload photos to wikimedia. Upload video to youtube. Convert all spreadsheets, documents, and presentations to wiki format and create wiki subpage of your page for each of them. Link to them here in a narrative that tells a story. High light the problems (engineering problems) you had and how you solved them.

Week4 Peer Review
Go to each team mates weekly summary wiki page. Read their activities and narrative. Then go the associated discussion page. Say something positive on this page. Try some constructive criticism. Add your name and a signature ~ by entering four tildes in a row to create a time and date stamp. Create a new category if another team mate has already commented here.
