FOLDING MECHANSIM

Fabrication plan:

steps	solutions
Objectives	To hang a bob over aluminum pipe
Materials	Acrylic sheets / Foam sheets / Iron slab`s piece
Materials chosen	Iron slab
Reason	Easily available and gives more weight for better folding

Program:

void setup ()
{
 pinMode(32,OUTPUT);
  pinMode(33,OUTPUT);
}
void loop()`
{
   digitalWrite(m31,LOW);        //pulley drops
   digitalWrite(m32,HIGH); 
   delay(3000);

  digitalWrite(m31,HIGH);        //pulley stops
   digitalWrite(m32,HIGH); 
   delay(500);
   
   
   digitalWrite(m31,HIGH);         //pulley rolled back
   digitalWrite(m32,LOW); 
   delay(3000);

   
   digitalWrite(m31,HIGH);         //pulley stops
   digitalWrite(m32,HIGH); 

}

COMPONENTS:

1. Bob (weighs around 450 grams)
2. Nylon strings (2 strings are layered with each other [a pair])
3. Aluminium pipe (to wind and unwind the strings to move the bob vertically)
4. 30 RPM Motor (to rotate the aluminium shaft)
5. Foam towers [a pair] (the string runs over pulleys to meet the bob)
6. Static pulley (attached on the top of foam towers)

Functionality test report

Report

The bob was cut into dimensions according to the need. The bob was tied with nylon strings and attached to the aluminium shaft which will help move the bob move vertically

Integration test results

The folding mechanism is synchronized with the system
