Turtle Robot, Talks Logo
The aim of this project is
to produce a low cost kit robot that aims to give someone an experience of making, not just a toy
The robot must be
- simple to build
- easy to use/program via software
- have a reusable element
- cost less than 20 EUR
The intent is to introduce kids and adults alike to building, making, electronics and software. For certain values of building, making, electronics and software.
This project is based off of work done for TRTL at the london hackspace - http://wiki.london.hackspace.org.uk/view/Project:TRTL
Statements
All design and build detail will be made free via open source principles.
The electronics will be made as re-usable as possible. Something based around the arduino platform (ATMEGA328) will be used.

Alternative to Soldering
Theres the option of using a breadboard and jumper wires, since the soldering is quite difficult and lengthy for a beginner.
