DESIGN 4 -- 2.5D SAUCE SQUEEZING MACHINE
The purpose of this design is to create and build a 2.5D (2D motion + a switch) motion system with some certain parts provided. The system will be controlled with electronic devices (Arduino).
Requirements and Constraints:
-The joints to connect all the parts will be designed and printed with 3D printer.
-The function, mechanical loading, required accuracy will be considered during the design.
-The mechanical and electric components will be able to work together and will be tested.
-The work area is 4 in x 4 in.
-The end effector will be powered by a servo motor.
-The product needs to be small and light in weight to be able to fit into a backpack. The difficulty of the assembly will also be considered.
Provided Materials:
-25 mm x 12.5 mm or 25mm x 25mm 8020 aluminum extrusion
-Two miniature or NEMA17 stepper motors
-Required belts and pulleys (timing and idle) or lead screws and bearings for 2 linear stages

Design Overview:
In order to create a system that is small in size, light weight, and easy to function, the system is designed to be a sauce squeezing machine. The whole system mainly consists of three aluminum bars. Two bars are placed on a piece of wooden board with screws and connecting designed and printed from the 3D printer. There is one screw, one motor, and two connecting joints on each bar to provide motion for the third bar in the middle. The third bar is attached with designed joints on each side that can also slide into the other two bars to provide movements. The third motor locates inside of the designed container on the third bar. A switch is placed through the middle bar of the motor. The forth motor is attached to one of the connecting joints on the third bar. (Detailed pictures and are shown below)
Function:
The system is able to operate in a x-y axis plane.
When the switch is off, it points to the left and squeezes the straw so that the sauce is not able to fall off. When the switch is turned on, it will rotate 90 degree clockwise, the straw is restored to its original shape, the sauce can fall off through it from the container on the top (video is shown below).
