Woven by Sun (太陽に織られた)
Woven by Sun is a prototype of a sun-responsive kinetic facade consisting of four modules that rotate every 90 degrees. Each module is triangular in shape, with a base length of 18 cm and a height of 9 cm. The prototype is fabricated through a digital manufacturing process using a 3d printer with pla+ filament as the primary material, it is actuated by a servo motor on each module, connected to an arduino, and paired with individual light sensors. This prototype is designed with two different mechanisms, each offering its own advantages and disadvantages.

Mechanism Explanation
1. First Mechanism
1.The servo acts as the main driver, operating based on light parameters detected by the light sensor.
2. The servo is connected to gears A and B.
3.The servo base is connected to gears C, D, and E.
4. Gear A drives gear D, which is connected to wing 1, while gear B drives gear C, and gear C drives gear E, which is connected to wing 2.
5. All gears move simultaneously when the system receives input from the light sensor.
6. Gears D and E rotate in opposite directions (opening to the left and right), allowing the kinetic facade to open and close automatically.
7. The wing frame functions to connect one module to another, forming a complete kinetic facade mechanism.
2. Second Mechanism
1. The servo functions as the main driver, operating based on light parameters detected by the light sensor.
2. The servo base is connected to the drive body, which supports the driving elements and the servo arm.
3. The servo arm moves driving element D, which is then transmitted to driving element C as the linkage leading to driving elements A and B, both of which are connected to the woven-bamboo wing panels.
4. All connected driving elements move simultaneously when the system receives input from the light sensor.
5. Driving elements A and B rotate in opposite directions (opening to the left and right), allowing the kinetic facade to open and close automatically.
6. Meanwhile, the wing frame functions to connect one woven-bamboo panel module to another, forming a complete kinetic facade mechanism.

Pros and Cons
First Mechanism
Pros
• Able to open and close with maximum range of motion.
Cons
• Requires more material.
• Takes longer fabrication time.
• The multilayer and more complex system results in a more complicated assembly process.
Second Mechanism
Pros
• Efficient motion distribution across the driving elements (a, b, c, d) allows a single motion source to operate multiple panels at once.
• The scissor-like movement system drives each wing in opposite
directions, making the mechanism simpler.
Cons
• Mechanical complexity increases due to the number of connecting elements (a, b, c, d), which raises the potential failure points and
maintenance needs.
• The wing opening angle is not yet optimal because the driving elements have limited length.
