<div><p>This notebook proposes a general introduction to <b>goal babbling</b>, and how it differs from <b>motor babbling</b>, in the context of robotics. Goal babbling is a way for robots to discover their body and environment on their own. While representations of those could be pre-programmed, there are many reasons not to do so: environments change, robotic bodies are becoming more complex, and flexible limbs, for instance, are difficult and expensive to simulate. By allowing robots to discover the world by themselves, we use the world itself—the best physic engine we know—for robots to conduct their own experiments, and observe and learn the consequence of their actions, much like infants do on their way to becoming adults.</p><p>This notebook requires no previous knowledge beyond some elementary trigonometry and a basic grasp of the Python language. The spirit behind this notebook is to show <em>all the code</em> of the algorithms in a simple manner, without relying on any library beyond <b>numpy</b> (and even, just a very little of it). Only the plotting routines, using the <b>bokeh</b> library, have been abstracted away in the <b></b> file. The archive contains the original notebook, the notebook with outputs, an html version of the notebook with outputs, and a python version of the notebook.</p></div>
