We learn the principles behind ‘gyros’, sensors that measure angular velocity with respect to the universe.

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.
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.
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.
A robot joint is a mechatronic system comprising motors, sensors, electronics and embedded computing that implements a feedback control system.
We recap the important points from this masterclass.
We learn how accelerometers and gyroscopes can be combined into an inertial navigation system capable of estimating position and orientation of a vehicle, without GPS.
