We are tracking product recommendations and mentions on various public social media platforms and blogs. They can help you identify which product is more popular and what people think of it.
Now, if you're doing it for real, the best and also most common method is simply, "use a computer". Many computer systems are really, really good at solving these equations and inequalities. You can also graph it and see on the graph every time it crosses zero. You can even do it for free without fancy software. There are a lot of web calculators that can do it, but one options is using wolframalpha.com. Source: 5 months ago

Do not go for a "one-use" calculator... Go for something that does it all if you know what you're doing. Go to wolframalpha.com. Source: 11 months ago
Some context: - Each "Card" you see is a reference to a block inside a big page called "Remarkable distributions". That page also contains more details (proofs, notable properties, ...) about each distribution. - The plots are generated using wolframalpha.com. I can just type "normal distribution" and I get a nice plot with different variations of the distribution's parameters. Source: 11 months 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 / 11 months 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: about 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
