Spiderbot coding

This time I did something completely different. I've always wanted to do a spiderbot but it needs so many servos that it's quite expensive. Here's a simple 4-legger code I wrote as a basic frame for a spiderbot I might do in the future. It can only go forward but with a method for every leg, it can easily be coded to do anything.

#include <Servo.h>

Servo legtakaoik;
Servo legtakavas;
Servo legetuoik;
Servo legetuvas;
Servo legtakaoikup;
Servo legtakavasup;
Servo legetuoikup;
Servo legetuvasup;
int eteen;
boolean jalka;

void setup()
{
  legtakaoik.attach(9);
  legtakavas.attach(10);
  legetuoik.attach(8);
  legetuvas.attach(7);
  legtakaoikup.attach(6);
  legtakavasup.attach(5);
  legetuoikup.attach(4);
  legetuvasup.attach(3);
}
void loop() {
  etuvas(90, false); // all servos to 90 degrees = center
  etuoik(90, false); // false = leg down, true = leg up
  takavas(90, false);
  takaoik(90, false);
  delay(200);
  eteen=10; // For testing only. Move forward 10 steps.
  delay(4000);
  for (int i=0;i<eteen;i++) // go forward
  {
    if (i=0) { // first step
      etuvas(120, true);  // move servo 120 degrees
      takaoik(120, true);
      delay(200);
    }
    else {
      etuoik(60, false);
      takavas(60, false);
      delay(360);
      etuvas(120, true);
      takaoik(120, true);
      delay(360);
    }

    etuoik(120, true);
    takavas(120, true);
    delay(360);
    etuvas(60, false);
    takaoik(60, false);
    delay(360);
  }
}
void etuvas(int i, boolean jalka) { // front left foot
  legetuvas.write(i);
  if (jalka == true)
    legetuvasup.write(180);
  else
    legetuvasup.write(0);
}
void etuoik(int i, boolean jalka) { // front right foot
  legetuoik.write(i);
   if (jalka == true)
    legetuoikup.write(180);
   else
     legetuoikup.write(0);
}
void takavas(int i, boolean jalka) { // rear left foot
  legtakavas.write(i);
   if (jalka == true)
    legtakavasup.write(180);
   else
     legtakavasup.write(0);
}
void takaoik(int i, boolean jalka) { // rear right foot
  legtakaoik.write(i);
   if (jalka == true)
    legtakaoikup.write(180);
   else
     legtakaoikup.write(0);
}
