Great video, thanks !  Getting a stable gait is a lot harder than it seems at first.  I succeeded after quite a lot of trial and error.  I still have not got my dog to turn on the spot, but I am working on it.  The geometry of turning circles and foot placement is interesting, could you do a video about that...

@ErrorClements.

Thank you so much!Trying to get into robotics,so here we go

@sally6779

Thanks so much for this amazingly informative video! I've had a look at your other uploads and they're all incredible resources for anyone into robotics, you've definitely earned a new sub for all the work you must have put in in order to produce these. Although I understood ‘enough’ to follow along, I keep getting stuck at the graphic you showed at 4:10 and can't fully get my head around what it means. What does Kp, or the s, 1/s stand for? steps? I'm probably overlooking something very easy here

@teerthraj_verma

Thanks 
Its really  hard to find such video where gaits, motion is explained in detail.

@maenhp2678

This is so cool, really appreciate it!
Could you recommend a paper to read regarding the dynamics of quadruped? Thanks

@juggernaut7453

Thank you so much for this tutorial! Its a wonderful introduction to quadruped robots and really helped me out. Have you published any paper or document about your work? I would like to reference and give credit to you.

@mikaeltrana8426

Really love your videos! This helped me out a ton when building my own quadruped and getting it to move correctly in Gazebo. I was wondering, I would like to give it a try to enable it to handle stairs as well, perhaps through some kind of reinforcement learning. What would you recommend to start looking into for solving something like that? Thanks again for the great content!

Hi, I am getting an error when running the script. "Could not load controller 'rear_left_shin_joint' because controller type 'effort_controllers/JointPositionController' does not exist"

@AtlastAtlantis

I think there's a "mistake" in the inverse kinematics. The angle you have represented in with a blue semi-circle is not atan(y/x) but pi-atan(y/x) so it would probably be easier to understand if you wrote theta1 = pi-atan(y/x) -atan(AG/OA) where pi-atan(y/x) would be blue to match your drawing. Thank you again for the great video, I just rewatched it. Best from Simon.

@fengliu9837

Thanks,I've learned a lot from your vedio!

@daffercoll1998

Nice video!

@rutgervisscher5527

Would be really interesting to see a video on the actual programming of the gait, how to go from the IK to the gaits... Or am I missing something here...

@oracid

Great video ! Thank you for sharing. Do you think this could work if I install Gazebo for Windows 10 ?

@1988trevor

thanks, it's very helpful

@givenbmugoni2578

Amazing. Want to build mine too

@ashwathwatchesyou

Hey, I've followed the instructions perfectly and have changed the chmod permission to allow gazebo to access the controller scripts. I have also installed the ros-noetic-control and controllers libraries. But the robot still cannot do the stand up function or change its pose. It just stands there in the crouch pose. Am I doing something wrong? Please help and thanks in advance.

@mikhaelsunil2383

Does this work with ros2?

@towerboi-zg3it

Very nice work! By the way, are you planning to have a github for this pkg? I think it's a good opportunity if you or someone would like to upgrade or debug something. One I have tried is migration from ros to ros2 humble env. Also, you may fixed it already, but at the beginning when I down load the code, there is some incorrect path to the mesh files in the urdf file, so it would be great if you have updated it already.

@lixiaokang1469

Hello, thanks for the great video.
I use Ubuntu 18 and ROS melodic. When launching the file, there are some errors. "ImportError: dynamic module does not define module export function (PyInit__tf2)" and "ERROR: cannot launch node of type [joy/joy_node]: joy". Do you have  any clue to fix these? Thank you!

@azmyin

Hi fantastic video. Are the gazebo assets publicly available?
