We learn the principles behind magnetometers, sensors that measure the Earth’s magnetic field.

We learn the principles behind accelerometers, sensors that measure acceleration due to motion and due to the Earth’s gravitational field.

We learn how to use information from three magnetometers to determine the direction of the Earth’s north magnetic pole.

We learn how to use information from three accelerometers to determine orientation.

If your knowledge of dynamics is a bit rusty then let’s quickly revise the basics of second-order systems and the Laplace operator. Not rusty? Then go straight to the next section.

For a binary image that contains multiple blobs we must first transform it using connectivity analysis or region labeling. Then we can describe each of the blobs in the scene we first need to transform the image using connectivity analysis. Each of the blobs can then be described in terms of its area, centroid position, […]

Vision is a critically important sense for humans and, in fact, for almost all animals. If it’s useful to us then surely it would be a useful sensor for robots.

It is common to think about an assembly task being specified in terms of coordinates in the 3D world. An alternative approach is to consider the task in terms of the relative position of objects in one or more views of the task — visual servoing.

A robot joint is a mechatronic system comprising motors, sensors, electronics and embedded computing that implements a feedback control system.

One very powerful trick used by humans is binocular vision. The images from each eye are quite similar, but there is a small horizontal shift, a disparity, between them and that shift is a function of the object distance.
