Homogenous Transformations in Robotics | Robotics 101
In this video, we cover another way of writing out the coordinate transformations in a more compact manner known as a homogenous transformation matrix.
A homogenous transformation matrix contains both the rotation matrix and a displacement vector into one matrix and makes it way easier to perform operations.
❓ Do you have trouble understanding or find this concept difficult?

This video is part of the Robotics 101 tutorial series which covers kinematics and modeling of 2D & 3D robots.
This tutorial lesson series starts from the 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 2D & 3D robots
2. Homogeneous Transformations for 2D & 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!

Inverse Kinematics of Industrial Robots (solved Example) | Part 3 | Robotics 201
Переглядів 2,7 тис.Рік тому
This is part 3 of solving the inverse kinematics of an industrial robot. The robot that we are doing the analysis on is ABB Robotics' IRB 120, which is a 6 DOF robot. We are doing full-fledge inverse kinematics which is figuring out the joint angles to make the robot's end-effector go to a particular position with a certain orientation. If you have any questions or confusion, comment below and ...

Inverse Kinematics of Robot Wrist (with solved example) | Robotics 201
Переглядів 3,1 тис.Рік тому
In this video, we solve a numerical example of doing inverse kinematics of a robotic (spherical) wrist. The objective is to figure out the joint angles that will make the end-effector reach the desired orientation. For the desired position, we will need to perform full-fledge inverse kinematics which we will be covering in the next video. If you have any questions or confusion, comment below an...

Please watch: "Inverse Kinematics of Robot Wrist (with solved example) | Robotics 201" ua-cam.com/video/4Wd3UqizTHM/v-deo.html ~ In this video, we introduce the concept of a robotic wrist. All industrial robots (normally) have a spherical wrist which means that the last three rotation axes intersect at a common point and this configuration is known as a robot wrist. Almost all industrial robots...
How to enable Dark mode in MATLAB (Step-by-Step)

After the longest wait, we finally got an official DARK MODE in MATLAB 2023! It's very simple to enable the dark theme and although it is in Beta development but it works very well. Let me know down in the comments your thoughts on it. Note: If you would like to try out any of the themes that I showed in the video (user mods), watch this video: ua-cam.com/video/rqL_6tOLuoQ/v-deo.html This video...

In this video, we talk briefly about how to identify the degrees of freedom of a robot and then we talk about what is meant by the inverse kinematics of a robot. We also do a quick refresher on what forward kinematics is and how it is related to inverse kinematics. Lastly, we talk about what a Robotic Wrist is and how we deal with IK by segregating the problem into the orientation and position ...
Forward Kinematics of Robot Arm in MATLAB

In this video, we do the forward kinematics of an industrial robot arm that has 6 degrees of freedom in MATLAB. First, we start off by writing the proper homogeneous transforms that relate the robot's end-effector (gripper) frame in the base frame, and then we code it up in MATLAB. ✨ Download MATLAB code here: www.zainullah.com/programming-source-codes/#MATLAB6DOF Hopefully, the video was easy ...

We do another example of the forward kinematics of an industrial robot in this video. The robot that we have is a 3-degree-of-freedom 3R robot with a robotic hand (gripper) that is commonly used for pick and place operations. A quick recap: Forward kinematics involves finding the location and orientation of the end-effector (gripper) of the robot given the joint angles which are called robot pa...

In this video, we talk in detail about how to do the forward kinematics of an industrial robot (more specifically a robotic hand). Forward kinematics is to find the location and orientation of the end-effector (gripper) of the robot given the joint angles which are called robot parameters.
