• An open source, educational, low-cost modern analog computer

  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

• Best software for parallel robot simulation?

  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.

• Anyone know if python can be used to make a MATLAB simulink clone (dragging and dropping elements)? If not, do you have recommendations of other languages that can do this best to make a desktop app?

  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

• Just introduced to diffeq last year. Curious how to go about modeling something like this.

  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

• Need software recommendations please

  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

• Software recommendations for simulation and visualization of dynamics of mechanisms (like a mountain bike)

  Try https://openmodelica.org/ and the standard library's multibody dynamics package. Source: about 2 years ago
