Seeing is an active process and our brain uses our eyes to find answers to questions — how we look at a scene depends on what we want to know. Eye tracking experiments measure where eye movement, where we look and what we pay attention to.

We revisit the important points from this masterclass.
For real robots such as those with 6 joints that move in 3D space the inverse kinematics is quite complex, but for many of these robots the solutions have been helpfully derived by others and published. Let’s explore the inverse kinematics of the classical Puma 560 robot.
Much of what we know about robots comes from fiction. Let’s look at fictional robots and the underlying reality.
The orientation of a body in 3D can also be described by a single rotation about a particular axis in space.
The orientation of a body in 3D can also be described by two vectors, often called the approach and orientation vectors.
We learn how to describe the orientation of an object by a 2×2 rotation matrix which has some special properties. Try your hand at some online MATLAB problems. You’ll need to watch all the 2D “Spatial Maths” lessons to complete the problem set.
