Excerpt from Maddie's Design Journal:
Basic Idea: A Painting or Paintings that do stuff as you walk by them
-Probably use light sensors as triggers like the robotic car race used
-So far-Samantha made a Lego frame for a Mona Lisa and is trying to make its tongue stick out. Currently using a motor and simple gearing. There was a 24 tooth gear on the motor, connected to another 24 tooth gear which was connected to the tongue, a 1:1 gear ratio.
Trial 1
The tongue whipped out of the ‘mouth’ hole in the paper and spun around very fast.
Idea: maybe if we switched the 24 tooth gear which is connected to the tongue with a 40 tooth gear the tongue will spin more slowly. This would be a 5:3 gear ratio. Also, making a longer tongue might help it stay in the mouth hole as it spins around.
Trial 2
The tongue went more slowly, but it still came out of the mouth hole in the paper and went around in a circle.
Idea: try using a motion module to move the tongue. Try the back and forth motion module.
Trial 3
The motion module is a good idea, but the tongue still sometimes comes out of the hole, or falls off of the motion module entirely.
Possible Problem
The current idea is to make the Mona Lisa (a bigger version, not the one we have right now) do multiple things when you walk by such as her tongue sticking out, her eyes following you (using lights on a similar back and forth motion module?), ears wiggle, hair move with wind?, etc. Looking at the size of our motion module, it might be easier to do one thing on each painting, rather than multiple things on one painting.
We started looking for more paintings to work with for our “silly art” exhibit, and came across a copy of the Mona Lisa drawn as if she were a Lego person! This would be perfect for our project, but we would still need to find more than one painting.
We went online and found some more Lego Art works, including Girl With a Pearl Earring by someone whose user name is Udronotto, and a Lego Van Gogh Self Portrait, and The Scream.
Idea
The Scream could actually scream!
