This lesson is part one of the series of lessons on the fundamentals necessary to represent the robot's configuration, and it gives an introduction to what we mean when we are talking about representing a robot's configuration.

This video also has a reading version that complements the video. Our suggestion is to watch the video and then read the reading for a deeper understanding. For the reading, refer to the link below:

I cannot wait to see how this course delivers what it promises - a good foundation knowledge on robotics. Anxiously waiting to see the unfolding of these very hard concepts to grasp. So far a great effort is made to make it simpler to explain these complex mechanics.

This is really good stuff. Helps clarify a lot of confusion.

I am so appreciative, Thank you alot. I struggled to understanding this orientation. Please continue and help a soul... we will create something awesome i promise that

Thank you for the great content! Could you recommend some books on Robotics Fundamentals?

This is nice. I’m using a motion sensor bno055. I’m getting Euler angles. But the problem is pitch is restricted 90, roll is restricted 180 and yaw is at 360. I also have the quaternion. How can I drive the absolute body frame orientation based on the reference frame or starting frame reference. Could you please help

Hi, if the exponential co-ordinates ωθ are given by [ 0 0.453 0. 262] then how to calculate the θ? I tried to follow the algorithm, but couldn't quite get there. I found the easiest method is to apply 'norm' function in matlab.
I got the correct answer = Sin -1(0.523) but could quite understand. Would you be able to explain? Thank you.
