Rotation Matrix | Coordinate Transformations | Robotics 201

We discuss why we need a rotation matrix and how we derive the rotation matrices along X-axis, Y-axis, and Z-axis.
We also talk about the two properties of a rotation matrix.

00:24 Rotation matrix along Z-axis
06:05 Rotation matrix along X-axis
06:41 Rotation matrix along Y-axis
07:19 Properties of a rotation matrix

In the next couple of videos, we take it a step further and apply coordinate transformations to 3D robots to see how it enables us to change the representation of an object from a body frame to a fixed frame (and vice versa).

This video is part of the Robotics 201 tutorial series which covers kinematics and modeling of 3D robots.

This tutorial lesson series starts out from the very basics of robotics (assuming no prior knowledge) and gradually builds on in bite-sized videos of 10 minutes or less. By following along, you will soon become extremely good in the kinematics and modeling aspects of robots. And these will help you to design and build robots.

Here's what we will cover in this video series:
1. Co-ordinate Transformation for 3D robots
2. Homogeneous Transformations for 3D robots
3. Forward Kinematics
4. Inverse Kinematics
5. Robotic wrists (end-effector)
6. End-effector Velocities and Jacobians
7. Singularities of robots
8. Gimbal Locks
9. Forces & Torques

I will be uploading 1 video per week. If you find these helpful, don't forget to share and subscribe!

hey man can you provide certificates too for both your courses 101 and 201 they both are exceptional and recommend me a book to further study kinematics

I do not understand, what you called "simple trigonometry". Why are there sin(theta) and cos(theta)?
