Year 9 Design & Technology Syringe Robotic Arm  Design Challenge Design Situation You are a designer at  Acme Robotics ,  Ltd . Your company has been asked to design a  toxic material-handling system  for  Thingamajigs Inc .  Thingamajigs   Incorporated  manufacture ¡® Thingymebobs ¡¯. During the manufacturing process, these ¡® Thingymebobs ¡¯ need to be moved from a work area (A) and then dunked into a tank (B) of toxic liquid before being placed in a drying area (C). At present this task is done by hand! Moving the ¡® Thingymebobs ¡¯ by hand is  boring  and  dangerous  now that a  toxic  material has been recently introduced into the manufacturing process.  The company has in the past had to pay a lot of medical bills due to injuries and illness caused by moving these ¡® Thingymebobs ¡¯.  Management feels that using a robot to move these ¡® Thingymebobs ¡¯ will free personnel for more important work, improve employee safety and improve productivity.  ?
Design Situation (continued) Your department head  has decided to put together several design teams. Each  design team  ( 3 people ) will develop and present a proposal for solving the material-handling problem.  Each team is to prepare a proposal for presentation to the CEO of  Thingamajig Inc . This  proposal  will be in the form of a  working model hydraulic robotic arm  and a  digital   design folio  which documents the teams design process. The design team that presents the  best  proposal and most  efficient  system will receive the contract ( PRIZE )!
Order of Operations Pick Dunk Place C) Drying Area The Design Challenge Using your robotic arm, you are to pick up in order (begin with #1) the 4 items ( Thingymebobs ) from Work Area A and transfer the items one by one to Dunking Area B and then place them in the corresponding numbered spot in Drying Area C.  ?  In dunking Area B, the  Thingymebobs  must be completely submerged to be counted.  ?  In Drying Area C the  Thingymebobs  must be placed, in order, (beginning with #1) on the numbered spots.  ?  The team will be allowed  3  tries  to complete the task in the least amount of time. Teams will be ranked as the top three shortest times for completing the task.  ?  At no time can the team use anything but the robotic arm to complete the task. Time penalties will be given for items dropped between picking, dunking and placing. (5 seconds per drop or human intervention) Pick, Dunk and Place! Work Cell Robot Base Pivot Area  (400 x 400mm) 1 2 4 3 A) Work Area 1 2 4 3 TANK B) Dunking Area Thingymebobs =
Roles of Team Members Each member of the team is responsible for the equal input into the design project.  Teams  must  nominate a  Team Manager  whose role will be to bring in the project smoothly and on time.  Each team member is to focus on a particular area of  R&D  (Research and Development) related to a specific part of the robot arm. Team organisation should be as follows:  Team member 1 : Design of a rotating base Team member 2 : Design of arm Team member 3 : Design of End Effector
