The best video for my level of understanding for odometry in motion. Of course, my intended self-study is inverse kinematics for a specific configuration using power curve tables for a specific robot on a specific surface. Thanks for your efforts in educating us with such clarity. It has been a long road for me but truly the circle with respect to some aspects of kinematics math has come full circle (no pun intended). You should write a collection of articles and publish it formally (unless you are doing so already). Many robotics clubs would welcome your efforts. My challenge is to correct for drift in small room (intentionally without GPS) using some dead reckoning with image markers on walls. Kind regards.

Hello teacher, let me ask if the 2 wheels of my mobile robot are not coaxial, what should be adjusted in the forward kinematics formula to give the same result with 2 coaxial wheels? Thank you so much

thank you so much for this great channel. I have tried to download Odometry simulation files. Unfortunately I could not access, it requires a permission from you DR. could you please make these files as public so that we can download it and apply it as you did in the video.

Thank you so much sir. So so interesting, can I get full of simulation files sir. I wanna know and study about Kinematics of Differential Drive Robots and Odometry more and more. Next I wanna know path navigation logic and dead Reckoning algorithm(For restaurant serving mobile robot), can you direct and suggest me how to study about it.

By path navigation logic, do you mean path planning? If so, I have several videos about that on my channel under playlist "robotics" (path planning using artificial potential fields, path planning using Probabilistic Road Maps", Path Planning using A* algorithm) and I have "path planning using Dijkstra Algorithm" under the playlist "machine learning". I also have a video on "dead reckoning" or "odometry" under the playlist robotics in video about "differential-drive robots".
