Information

• Tittle: Let's build a modular snake robot
• Event: Microbotics summer Workshop. From 2nd to 6th of July 2013
• Place: ETSIT. Universidad de Malaga
• Speaker: Juan González Gomez
• Students: 20
• Hours: 6 (session 1)
• Date: 02/Julio/2013

Abstract

This is the session 1 of the 2013 Microbotics Summer Workshop organized by the Electronic Technology department at University of Malaga. In this session, a printable modular snake robot, consisting of 9 modules is assembled and the main locomotion principles are presented.

BILL of Materials

• 10 Repyz pro modules, already assembled
• 3 Skymega boards, Arduino compatibles. These boards are used only during the session 1 for showing the different locomotion gais. In the following session the students had to program the EZ430-RF2500 boards, connected to some extension boards that include connectors for the servos and the sensors.
• 3 battery holders (for 4 AAA batteries) already assembled
• 3 pairs of mounting brackets for attaching the battery holders to the modules
• 60 M3x10 mm bolts
• 60 M3 nuts

Software

Before using this software, make sure you have installed the Ardusnake Library

Unimod_test1.ino	Example 1: different oscillations of 1 module. The oscillation changes when the test button is pressed
Unimod_test2.ino	Example 2: Oscillation of 2 modules. The phase difference is changed when the test button is pressed
wave.ino	Example 3: The wave. 9 independent modules are oscillation so that a wave is generated
pp_test.ino	Example 4: Locomotion of the pitch-pitch minimal configuration. When the test button is pressed, the gait is changed
pyp_gaits.ino	Example 5: Locomotion of the pitch-yaw-pitch minimal configuration. When the test button is pressed, the gait is changed
py6.ino	Example 6: Locomotion of a 6 module pitch-yaw snake
