When I create a prototype of something I want to create is sketch out my design. I did a few designs last week, so I wanted to move on to my second step. The second step I like to do in my iterative processes is create a CAD model. I used to go to a school where we would use CAD every day to create ideas and bring them to life. CAD is by far one of my favorite steps in the iterative process. When opened Fusion 360 it felt like a blast from the past. I quickly whipped up a 3D version of one of the sketches I made.
The wooded flat part will act as a top. If you look at the second picture you will see that there is an indent in the bottom so the top will fit snuggly to the pot. The blue part represents a motor that will rotate the curved arm. There is a hole in the arm to fit a spoon. When turned on the motor will make the curved arm rotate left and right following the circular path.
I then when to the IMA lab to recreate my CAD design. I used cardboard to cut out the top. Then I used dowels to create the arm and reenforced the two dowels with triangles on each side so the arm is not as flimsy. I then attached cardboard to the bottom of the dowel so the dowel doesn’t fall through the top. Then I connected a spoon onto the dowel to show how the mechanism works all together. Below is a video of my final creation.
