SpiderRobot

Overview

SpiderRobot is a robotic project built with an Arduino and several servo motors to mimic the movement of a spider. The robot can perform actions such as standing, sitting, and winking, and it uses an ultrasonic sensor to measure the distance to objects in front of it. This project is a great introduction to working with servos, Arduino programming, and basic robotics.

Components

• 1x Arduino Board
• 12x Servo Motors: Control the movement of the robot's legs.
• 1x Ultrasonic Sensor (HC-SR04): Measures distance to objects.
• Jumper Wires and Breadboard
• External Power Supply: Depending on the servos used, an external power source may be necessary.

Pin Configuration

• Trig Pin (Ultrasonic Sensor): A2
• Echo Pin (Ultrasonic Sensor): A1
• Servo Motor Pins: Digital pins 2-13 are used to control the 12 servo motors.
  • Servo Motor Layout:
    • Motor 0: Pins 2, 3, 4
    • Motor 1: Pins 5, 6, 7
    • Motor 2: Pins 8, 9, 10
    • Motor 3: Pins 11, 12, 13

Features

• Stand: Positions the robot in a standing posture using predefined servo angles.
• Sit: Lowers the robot into a sitting position by adjusting the servos.
• Wink: Performs a winking action with one of the legs, simulating a wink gesture.
• Distance Measurement: Uses an ultrasonic sensor to measure the distance to the nearest object and prints the value to the serial monitor.

How It Works

1. Setup: The servos are initialized and attached to their respective pins, and the ultrasonic sensor is set up for distance measurement.
2. Stand Function: The robot adjusts its legs to a standing position.
3. Distance Calculation: The calc_distance() function triggers the ultrasonic sensor to measure the distance to an object in front of the robot.
4. Wink Function: The robot performs a winking action with one of its legs.
5. Sit Function: The robot lowers itself into a sitting position.
6. Infinite Loop: The robot halts further actions after completing the sequence.

Installation and Setup

1. Clone the Repository:

   git clone https://github.com/yourusername/SpiderRobot.git
   cd SpiderRobot

2. Upload the Code:

Open the SpiderRobot.ino file in the Arduino IDE. Connect your Arduino to your computer. Upload the code to the Arduino board.

3. Wiring:

Connect the servo motors to the appropriate digital pins as specified in the pin configuration. Connect the ultrasonic sensor to pins A1 (Echo) and A2 (Trig).

4. Power:

Ensure the servos are powered properly, either through the Arduino or with an external power supply.

Usage

Once everything is set up and the code is uploaded:

The robot will start in a standing position. It will measure the distance to an object and print the result to the serial monitor. The robot will perform a winking action, followed by sitting down. To see the distance measurements, open the serial monitor in the Arduino IDE at a baud rate of 9600.

Customization

Servo Positions: Adjust the angles in the stand(), sit(), and wink() functions to modify the robot's movements. Distance Thresholds: Add logic to perform different actions based on the distance measured by the ultrasonic sensor.
