Olivia Nixon HW 15 9 May 2011 This video shows robots assembling the different parts of cookies (cream filling and the actual cookie). I chose this video because I am a General Engineering Major looking to concentrate in Manufacturing Engineering, and what is more fun than ‘manufacturing’ cookies? The robotic arms are linkages and move in a specific pattern to make sure each cookie is assembled with filling. In designing this robot and linkage a lot of things will no doubt need to be taken into consideration, but for this project I will discuss only those issue related to the linkage. When designing specifically the robotic arm, the distance it needs to reach will have to be taken into consideration. This will depend on the arrangement of the cookies and filling on the

Unformatted text preview: moving surface below the robotic arm and the programming of the robot. The rate at which the arm will move (amount of cookies assembled per sec/min) will also need to be taken into consideration when designing the arm For the linkage shown, assume the robotic arm portion AB assembles 30 cookies per minute. This equates to a constant angular velocity of ω AB = 20 rad/s counterclockwise and ω BC = 26 rad/s clockwise (not constant) at this instant. Also note that link CDE is stationary (always 90° to BC) and will not rotate. Find the angular velocities of CDE and the angular acceleration of BC at the instant shown, with Θ = 45°....
