BrachioGraph - the cheapest, simplest possible pen-plotterP

Share on Twitter Follow @BrachioGraph
---------------------------------------------------------------------

BrachioGraph - arm-writer - is an easy-to-build pen-plotter, driven
by a library of simple Python applications.

A BrachioGraph can be built for about EUR15 in an hour or so, using a
Raspberry Pi computer, hobby servo motors and household items. The
BrachioGraph library is published on GitHub abd includes simple
Python code to drive the plotter and vectorise bit-map images.

BrachioGraph plots cheerful, low-fi drawings, and can produce robotic
sketches using a variety of drawing implements.

The BrachioGraph communityP

BrachioGraphs benefits from contributions from the open-source
community, and independently-created community resources. These
include videos, brachio.me, a web version of the linedraw software
used to vectorise images and 3D printed plotter components.
