Story

Bio-inspired Robotics: An Emerging Research Field Bio-inspired robots are a new kind of research platform developed to fulfill the two-pronged desire of humans: enhancing the quality of human life by incorporating artificial systems in it and, at the same time, improving the system design through integrating biology with it.

In this project, an Arduino was used to build a 4 arms star-shaped robot called "STARY" that moves like a real-world animal which is called Bio-mimicry.

How It was Built

To construct the model a cardboard sheet was used and a sea Star-shape drawn on the cardboard but only with for arms.

1. Cut the cardboard in an x-shape

2. Make the arms finger-like by making a slight cut between each part of it so it looks like a fingertip

3. Using the glue gun and stick straw on a path to allow the nylon to go through

4.Attach the servo motor and fix it in the disc area

5. Connect the nylon thread and making it pass by the straw pieces and tie it to the servo motor.

#include <Servo.h>
int FRONT = 9;
int BACK = 10;

Servo frontLegs, backLegs;

void setup() {
  frontLegs.attach(FRONT); 
  backLegs.attach(BACK);
  frontLegs.write(90);  //Center the servo
  backLegs.write(90);   //Center the servo
  delay(500);          //Wait 5 sec (This gives us time to unplug the arduino
                        //  so we can affix the legs.
}


void loop() {
  frontLegs.write(0);        //move front leg a little
  delay(200);
  backLegs.write(180);         //move back leg a little
  digitalWrite(13,LOW);       //LED off
  delay(200);
  frontLegs.write(180);       //move front leg a little
  delay(200);
  backLegs.write(0);        //move back leg a little
}
