When it comes to describing a blob we can do more than just area, centroid position and bounding box. By looking at second order moments we can compute an ellipse that has the same moments of inertia as the blob, and we can use its aspect ratio and orientation to describe the shape and orientation […]

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 use information from three accelerometers to determine orientation.
We learn how to describe the orientation of an object by a 3×3 rotation matrix which has some special properties.
The orientation of a body in 3D can be described by three angles, examples of which are Euler angles and roll-pitch-yaw angles. Note that in the MATLAB example at 8:24 note that recent versions of the Robotics Toolbox (9.11, 10.x) give a different result: >> rpy2r(0.1,0.2,0.3)ans = 0.9363 -0.2751 0.2184 0.2896 0.9564 -0.0370 -0.1987 0.0978 […]
We learn how to describe the position and orientation of objects in the 3-dimensional space that we live in. This builds on our understanding of describing position and orientation in two dimensions.
We consider a robot, which has two rotary joints and an arm.
We consider the simplest possible robot, which has one rotary joint and an arm.
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.
We resume our analysis of the 6-link robot Jacobian and focus on the rotational velocity part.
