Reading an Image From a Local Camera
lesson
Most computers today have a built-in camera. Let’s look at how we can grab images directly from such a camera and put them in the MATLAB workspace.

lesson
The end-effector is not able to move equally fast in all directions, and that in fact depends on the pose of the robot. We will introduce the velocity ellipse to illustrate this.
lesson
For a redundant robot the inverse kinematics can be easily solved using a numerical approach.
lesson
We revisit the simple 2-link planar robot and determine the inverse kinematic function using simple geometry and trigonometry.
lesson
The orientation of a body in 3D can also be described by two vectors, often called the approach and orientation vectors.
lesson
We learn how to describe the orientation of an object by a 3×3 rotation matrix which has some special properties.
lesson
We summarise the important points from this lecture.
lesson
We run into problems when we take all of the pixels in a box around an input pixel and that pixel is close to one of the edges of the image. Let’s look at some strategies to deal with edge pixels.
lesson
Building a highly accurate robot is not trivial yet we can perform fine positioning tasks like threading a needle using hand-eye coordination. For a robot we call this visual servoing.
lesson
The pinhole camera simplifies the geometry but in practice it results in very dark images. Cameras, as well as our eyes, use a lens to form a brighter image but there are consequences.
