The aim of this project is

to produce a low cost kit robot that aims to give someone a sense of experience, 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 -


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.
