This part discusses what the word robot means to roboticists and the wider public, the history of the field, and the different forms that robots take today. A definition that will serve us well is:

a goal oriented machine that can

sense,planandact

We then move on to cover how we can represent the position and orientation of objects in 2- or 3-dimensional environments in terms of graphical coordinate frames. The objects might be robots, cameras, objects or obstacles. In order to use these frames in a computer program we need an appropriate representation and we discuss vectors, orthonormal rotation matrices, triple angles, homogeneous transformation matrices and quaterions.

Finally we discuss motion, how to generate a sequence of coordinate frames that represent smooth motion from one pose to another. We also consider how to process information from sensors on a moving frame to determine the pose of that frame.
