So, the last project!
I saw this sentence on the page of week7
This rule totally makes sense, and I totally agree, but don’t plan to follow it, especially not for the last Fabrication project.
Yes, I am going to build something super unnecessary and super useless, but super funny — a lipstick applying machine!
Simone Giertz — the queen of shitty robots!
I love Simone and her useless but awesome robots. As a fan of her, I subscribed her on Youtube and watched all her videos, among all the robots, my favorite one is the lipstick robot:
I decided to make a similar but portable one as my final project. I plan to remove all the heavy metal arms instead of using light transparent acrylics and using a suction cup to stick it on a mirror.
For the mechanism part, I found this gif picture which is very helpful for me to understand and design the motions.
Prototype 1: cardboard + nails + Arduino kit 6v motor
Conclusion: 3v motor is useless! It’s just soooooo weak, can lift nothing!!!!!!!
Prototype 2: 6mm acrylics + screws +stepper motor + things I found on workshop
Since the 6v motor is so weak, I dug my toolbox and found a stepper.
It works!!!! However, the biggest disadvantage of using a stepper is I have to link a stepper driver and an Arduino board to my project. It just caused too many trouble: the wires are so messy, the micro-controller may be destroyed by accident…. So I decided to improve the second prototype and make the final one
So I decided to improve the second prototype and made the final one:
Final work: Transparent Acrylic + Low-Speed 6v motor + Screws
How to attach the motor to acrylic? I tried two different ways.
a, something’s holder:
not very stable.
b, customized holder :
motion track test
Balance the height of two sides.
The color is called crazy cranberry…. if anyone is curious….
I attached everything to a mirror-ish board….
I really like the details of this low-speed motor.
How it works?
the user(myself) says this machine is fantastic!
I still remember you asked us what’s our favorite thing we built by ourselves at the first class, my answer was I had never built anything ever. But only 7 weeks later, I made so many practical/funny/beautiful things! The feeling of holding a physical project is so satisfied!
Thank you for giving us the amazing 7 weeks! I had so much fun!
