These machines are celebrated at the [[http://punkinchunkin.com/|World Championship Punkin Chunkin Competition]]. Competitions like these teach new generations of engineers valuable skills. To enter the competition, we need to create a machine capable of launching a pumpkin extreme distances(in the thousands of feet), while keeping in mind price, manufacturability, feasibility, and safety. Furthermore, the machine has to adhere to the [[http://punkinchunkin.com/machine-rules|rules of the competition]] as stated by the WCPCA official rules and safety handbook. We plan to reach these goals by optimizing less conventional trebuchet designs using advanced static and kinetic modeling. ===== The Team ===== **-----------------------------Henry Wang ---------------------------------------------------- Alex Novoselov -------------------------- Matthew Lee ------------------------------- Kevin John---------------------**\\ [[http://dap.cooper.edu/doku.php?id=start:classes:principlesofdesign:pumpkinchunkin:start:henry_wang|{{:start:classes:principlesofdesign:pumpkinchunkin:start:henry.png|Henry Wang}}]][[http://dap.cooper.edu/doku.php?id=start:classes:principlesofdesign:pumpkinchunkin:start:alex_novoselov|{{:start:classes:principlesofdesign:pumpkinchunkin:start:alex.png|Alex Novoselov}}]][[http://dap.cooper.edu/doku.php?id=start:classes:principlesofdesign:pumpkinchunkin:start:matthew_lee|{{:start:classes:principlesofdesign:pumpkinchunkin:start:matt.png|Matthew Lee}}]][[http://dap.cooper.edu/doku.php?id=start:classes:principlesofdesign:pumpkinchunkin:start:kevin_john|{{:start:classes:principlesofdesign:pumpkinchunkin:start:kevin.png|Kevin John}}]] =====Introductory Video===== http://youtu.be/NgXeXiTTDNo =====Trebuchet Development===== [[http://dap.cooper.edu/doku.php?id=start:classes:principlesofdesign:pumpkinchunkin:start:Acrylic|See the acrylic phase here]]\\ [[http://dap.cooper.edu/doku.php?id=start:classes:principlesofdesign:pumpkinchunkin:start:development|Follow our development here!]]\\ =====Draw Bot Work===== [[http://dap.cooper.edu/doku.php?id=start:classes:principlesofdesign:pumpkinchunkin:start:drawbotpics|Pictures of our Drawbot!]]\\ [[http://youtu.be/piFEbRpzJGo|Motor Controller Test]] {{:start:classes:principlesofdesign:pumpkinchunkin:punkin_chunkin_stepper_motors.pdf|Summary of Major Components}} =====Timeline and Schedule===== {{:start:classes:principlesofdesign:pumpkinchunkin:gantt.png|Gantt Chart}} ^ ^ Monday ^ Tuesday ^ Wednesday ^ Thursday ^ Friday ^ ^9:00 |ML AN HW KJ|ML AN |AN HW KJ |ML HW |HW | ^10:00|ML AN HW KJ|ML AN |AN HW KJ |ML HW KJ |HW | ^11:00|Physics L |ML AN |ML |ML AN KJ |ML AN HW KJ | ^12:00|ESC | |ML AN |ML AN |Physics L | ^1:00|ML | |AN | | | ^2:00|ML AN HW |AN |AN HW KJ |Physics L |EID103 | ^3:00|ML AN HW KJ |AN |AN HW KJ |Physics L |HW | ^4:00|AN HW KJ |ML AN |AN HW KJ |KJ |HW | ^5:00| |AN | |AN | | ^6:00|AN |ML HW |AN HW |EID103 | | ^7:00|AN |ML HW |AN HW |EID103 | | ^8:00| | |HW | | | ^9:00| | | | | | =====Rising Bed====== {{:start:classes:principlesofdesign:pumpkinchunkin:start:punkin_chunkin_hoq.pdf|House of Quality}}\\ {{:start:classes:principlesofdesign:pumpkinchunkin:start:punkin_chunkin_bed.zip|Download all of our Solidworks models}}\\ [[http://dap.cooper.edu/doku.php?id=start:classes:principlesofdesign:pumpkinchunkin:start:bed_images|Images of the Bed!]]\\ [[http://www.youtube.com/watch?v=z4FrvcPhBGE|Animation of Operation]]\\ {{:start:classes:principlesofdesign:pumpkinchunkin:punkin_chunkin_bill_of_materials.pdf|Bill of Materials}} ======Final 6 Sketches for Critique====== {{:start:classes:principlesofdesign:pumpkinchunkin:start:img_3123.jpg?200|}} {{:start:classes:principlesofdesign:pumpkinchunkin:start:img_3121_-_copy.jpg?200|}} {{:start:classes:principlesofdesign:pumpkinchunkin:start:imag0042.jpg?200|}}\\ {{:start:classes:principlesofdesign:pumpkinchunkin:start:imag0041.jpg?200|}} {{:start:classes:principlesofdesign:pumpkinchunkin:start:imag0038.jpg?200|}} {{:start:classes:principlesofdesign:pumpkinchunkin:start:imag0037.jpg?200|}} ====== Minutes ====== [[http://dap.cooper.edu/doku.php?id=start:classes:principlesofdesign:pumpkinchunkin:start:Minutes|You will find our lovely minutes here.]] ====== Summer Minutes ====== [[http://dap.cooper.edu/doku.php?id=start:classes:principlesofdesign:pumpkinchunkin:start:SummerMinutes|You will find our lovely independent study minutes here.]]
