coding

#include <Servo.h>       // import servo control functions
Servo myservo1;
Servo myservo2;

int currentValue = 0;
int targetValue = 0;
int angleValue = 50;


void setup() {
  pinMode(9, OUTPUT);
  pinMode(10, OUTPUT);
  //Serial.begin(9600);
   myservo1.attach(9);
   myservo2.attach(10);
}

  /*
  if(digitalRead(5)==HIGH) {
    targetValue = 90;
  } else if(digitalRead(5)==LOW) {
    targetValue = 0;
  }
  */
 
 
  /////////////////////////////////////////////////////////////////////////
  //DECIDE + OR -
  if(currentValue<targetValue) {
    currentValue = currentValue + 1;
  } else if(currentValue>targetValue) {
    currentValue = currentValue - 1;
  }
 
  /////////////////////////////////////////////////////////////////////////
  //CHECK VALUE
 // Serial.println(currentValue);
 
 
  /////////////////////////////////////////////////////////////////////////
  //SEND VALUE TO MOTOR
  myservo1.write(currentValue);
  myservo2.write(170-currentValue);
 
 
  ///////////////////////////////////////////////////////////////////////////
  //MAKE IT NOT TOO FAST
  delay(50);
}


But there is some problem that two motor can not start at the same time. It could be the problem of motor because when it is close to 0 or 179 degree, it is not accurate. We will try to use program to control it since we have already built everything.

1:15 Full size Testing

Scissors Mechanism

Attempted using 1 motor to link up two motions but failed.

We will try to operate using two motors.
