Introduction

Ardusnake is an Arduino Library for generating easily the locomotion of modular snake robots. It is based on sinusoidal oscillators which drive the servos.

Architecture

ArduSnake Architecture (click para ampliar)

The ArduSnake library comprises the following layers:

• Oscillators: This layer is in charge of oscillating the servos sinusoidally. Just with these oscillations the locomotion of worm, snakes and other modular robots can be achieved.
• Worm: It offers an easy API for the locomotion of worm robots (locomotion in 1D) (alpha stage)
• Snake: Locomotion of snake modular robots (in 2D) (Future work, not yet implemented)
• User Application: The user can use the previous layers for the locomotion of the robot.

Tutorial

The first step is to install the ArduSnake library. Please follow these instructions .

Oscillators Layer

Example 1: Hello world

This example just makes a servo oscillate, using the default parameters

• Open the example oscillator_test1 from File/examples/ArduSnake. The example works directly with the Skymega board. If you are using an Arduino, you have to comment and uncomment some parts of the code.
• Attach the servo
  • If Arduino, connect the servo to pin 8
  • If skymega, connect the servo number 2 (see figure 1)

Example 2: Setting the oscillator parameters

Example 3: Oscillation of two servos

Example 4: A mini-wave

Download

Installation

The current version is being developed under Arduino 22 IDE. It may work with newer version, but I have not tried it.

• Download the library: ArduSnake-001.zip
• Uncompress it in your working directory
• Copy the folder ArduSnake under the sketchbook/libraries arduino folder (it is located in your home directory)
• If you are using the skymega board instead of an Arduino, copy the folder skymega under /home/sketchbook/libraries
• Launch the Arduino 22 IDE
• The menu Ardusnake containing some example should be accesible now from the File/Examples menu

Changelog

Ardusnake 001:

• Initial version
• The oscillator layer is working
• Some examples on how to use the oscillator layer written
• The worm layer is still in alpha stage (Do not use it yet)
• The snake layer has no been started
