It's incredibly easy to use and the regular reminder from the app about practicing more keep you consistent. Besides,in my opinion,it also can be not only a tool for learning languages,but a good entertainment for kids too. I've been practicing here almost every day throughout the year and i highly recommend Duolingo:))
Duolingo is a quite nice language learning app for the begginers and for those who want to know a certain language on a pretty good medium level(It's like something between A2-B1,i suppose). Moreover, I'd like to admit it's can be useful for kids as well because the app has cute design and playable interactions , challenges and its own little app - shop where you can buy different bonuses for you ,and in my opinion,children could like an idea of learning languages in a playable form. Though, Duolingo can be rather annoying, when you miss one or two days of studying ,so it'd be really awesome if my brother,for example, who uses this app ,could make his own studying schedule here.

Duolingo: a language-learning app that uses points, levels, and rewards to keep you motivated. This is the most effective when you do it with your friends or a group of people who share your learning goals. I got really addicted to checking my leaderboard rankings everyday. Source: 11 months ago
Hi! I wish I'd seen a post like this a few months ago. I would have been interested then. By now it's a little late for me. I just signed up for the 2 week free trial since that's about all the time I have left before I leave. If you can, use a desktop computer/laptop to do duolingo.com and it will have no ads and unlimited hearts! Not as convenient as the app on a phone but saves tons of time and you can do it...

I appreciate the energy to help, but if there are 5 posts in a day all on the same topic with the answer 'use duolingo.com' I don't expect anyone who has the "I'll just create a reddit post" idea to find this post and read it, they didn't read any of the others. Source: about 1 year ago

I have used https://openmodelica.org/. It's another one of those "invest substantial time understanding what they are doing, and you will likely be rewarded." Simple things are simple, but I found it took longer than I would have like to bang out e.g. a PID algo with a particular motor and load. If you want to try this, buy the book, and follow it to the end. Then keep learning, as you build more and more... - Source: Hacker News / about 1 year ago
If the robot simulation doesn't need to pick up stuff or take into account changing contacts with other objects you can use Modelica's Multibody library which you can run for free with OpenModelica. This will be more accurate than other simulators because modelica can analytically solve the dynamics equations. You don't need to write them either just to connect blocks for various components.

OpenModelica consists of a combination of graphical and written components to simulate dynamic systems. I don’t know what control system feature set might be available. AMESIM is a more extensive paid tool that operates on the same Modelica modeling language. IIRC, at least Simuscape operates on Modelica under the hood. Source: about 1 year ago
It shouldn't be too difficult to model in Modelica. You could approximate the pendula in 1D with masses on springs or just use Modelica's multibody library. Source: over 1 year ago
Modelica is a good start, at the very least in showing how to break a complex machine with many physical phenomena into components. Modeling accuracy and ease are generally opposed. Https://openmodelica.org/. Source: almost 2 years ago
