I'm working on a robotic hand and I would like to simulate different joints and tendon insertion points before starting to actually build it.
I've been googling and found things like Solidworks and Autodesk, that seem very costly for a hobbyst like me but also I don't quite fully understand their capabilities (just CAD? 3D modelling but not simulation? Simulation but not interactive?). I've also found things like FreeCAD which seem to me somehow abandoned or just for CAD and not for simulation.
Another requirement would be interactivity of the simulation, not just rendering.
I don't have a problem with commercial software, but I'm looking for a reasonable cost for a hobbyst, not an engineering company.
Is there a software out there that meets all this requirements? Or should I use several programs each for a specific purpose?
