Can we simulate a real robot?

[@robinkarlsson1460]

I really love this format where you walk us through the whole process of you actually struggling and powering through. Your enthusiasm and positive attitude is also very contagious! I could watch your videos all day just for that reason. And PS to anyone reading this: the book is frikn awesome. I've done some courses on ML and I can tell you it's absolutely brilliant, both for newcomers and intermediates.

[@sentdex]

Thanks! I enjoyed making this style of video and it's definitely one of my personal favorites in a while. Glad to hear you also enjoyed the book, thank you for sharing your thoughts!

Yeah half of robotics and machinelearning especially nvidia specific stuff is going through tedious documentation.

[@kornelillyes2848]

I have been waiting for something like this since I fiddled around with simulating robots in Unity a few years back. Make. A. Series. Seriously. I love this.

[@sentdex]

Definitely looking to continue with this project, have already made some good progress for the next part too :)

[@owiela]

I've also been thinking of doing this. 3D printing robots, then make them learn how to move with machine learning. Will be awesome!

[@AkshatSinghania]

[@CochDot]

I was always fascinated about training a project in a simulation and export its results to world with brutal and breaking physics. This seems a good choice. "I feel future".

[@pistonsoup3749]

This how they do control algorithms for rockets and aircraft! Build a simulation, then go fly. Alot of times there even using a kalman filter against the simulation results and real life!

[@drydenstewartenterprises]

This is awesome, Thank you for this! I have been working on a project that I have known that eventually, I will need to have a simulation for some of the machine learning, but I had no idea where to start. This is a great start!

Awesome, good luck with the project!

This is EXCATLY what i would have needed back in early 2021. I did my Bachelor Thesis in simulating and modeling a robotic manipulator and generating a path using genetic algorithms. I digged a little bit into physics engines (or something like ROS) but ended up using simple 3D Plots which took a shit load of time to calculate and animate... Really looking forward for your series!

I think that ROS would be ideal for communicating between your controller script and the script running the sim. You would just have a topic to which you would listen to in the sim and publish to it from the controller. BTW. Awesome work

🤫 I’m thinking: Calibrating what the simulator can do/"is allowed to do" based on what the robot dog can do (possibly for real) (extent of movement, acceleration, refresh rate etc.). Simulation runs only seem to make sense within the limits of the robot dog, not the simulator. Love this exploratory format!

Totally new to robotics, but would something like ROS work better for this case? Seems to be a common platform for robotics.

Its pretty obvious the sliding is due to joint oscillation which does occur even with servos with a bit of force applied to them.

[@sentdex]

Not sure where your original went, I checked spam too. Yeah there are some definite features in sim that I've seen that look insanely fancy. Unfortunately I am a total ROS noob. I know what it is and that's about it. I keep controlling my robots serially with pyserial :P If you know of a great intro to ROS that ramps up to something like this, let me know. It's a subject I've been wanting to dive into eventually. Also try replying with the docs maybe again.

[@ronaldtong8275]

Great video, however after putting together Bittle, (as mentioned in its manual) small things like putting on the rubber "socks", reversing direction of the battery to change the centre of gravity, all these will significantly impact gait of Bittle, which I highly doubt can be simulated in virtual environment (without very detailed modelling of the say dimension and shape of battery) Bittle's gait is basically simple half sine curve, which "supposingly" should allow it to walk basically but in reality, i find it wobble left and right each time Bittle raises a leg, which again i doubt can be modelled virtually without great level of detail. For quadruped-type of robots, shouldn't we be heading down the ROS route instead? Personally i have not used Omniverse before so i can be totally wrong

[@ciarfah]

I presume since it's Nvidia it's supposed to integrate easily with their machine learning tools. I'm not sure how well something like Gazebo would be used to train an AI, it might be just as easy, I don't know

[@punkson]

It seems Omniverse is analigous to Gazebo as opposed to ROS. Gazebo is a simulation environment that can be directly integrated with ROS to setup controls of the robot in the simulation.

[@NickSpeer]

nvidia software - really powerful stuff that's nearly impossible to figure out

[@sahanmendis3369]

Oh my god! how do you learn this stuff? I think simulations could save a lot of time for robotics developers so they don't have to deal with the electronics and complicated background earlier in the development.

[@daniellaucht5560]

I really appreciate your work. I learned Machine Learning 2 years ago with your videos and others. I always liked how you present your work and that you have no problem to admit when you can't do something 100% yet. You have a clear voice, and I never had any issue to understand what you say. I am from Germany. By the way, Panda it the name of the Robot from FRANKA EMIKA 😉 On this video I sadly had some issues to rebuild it. I really want to accomplish this and build my own solution for the Reinforcement Learning for the robot. What I don’t understand is If I need the simplified Script you created at 7:04? How do I create a scene as .usd like Bittle.usd? How should I structure the file locations for everything I need for manual control? I hope so much you find the time to answer 😊

[@sentdex]

7:14 was gym, so nope. USD is what omniverse app saves, so I just manually build and adjust in Isaac sim, then save, that makes a USD and is default stored in the Isaac directory, which can then be loaded. Id be happy to answer more and share the files, I can probably slap them into github or something. Feel free to email me [e-mail]

Hi sentdex! Im dealing with an similar problem in RL with Isaac-Sim, where I’m trying to teach a mobile robot to park. I have a lot of problems with the simulation program, because I don’t really know what are the limits of the joints of my robot, so that I can’t set my observation and action space correctly. Did you figured out how to set the limits of each joint in the simulation, so that I can use them to set the obs and action space ? I would appreciate if we can chat a little bit more detailed on about dealing with the Isaac sim simulator and it’s dynamic library? Kind rewards!

[@Denetony]

Oh gosh, you started with the msot difficult simulator. When I used Isaac sim.... I felt your pain. The documentation is horrible. There's other sims that are easier to work with but are definitely worse in terms of limitations (ROS gazebo, pybullet, VREP)

Start by using « the code you wish you had » from the highest level. Then break it down and implement it. It will help you figure out what you’ll be needing in order to achieve the goal. In other words, start by moving away from the stress of having to figure out thousands of details. Act as if someone else will do it later. You first focus on what you’re trying to do and let the _how_ emerge. This will also help you avoid coding useless low-level things that look important at first but then prove unneeded for the current focus. HTH.
