Sudeep, The topics related to sympy.physics.vector/mechanics are still possibilities. I will have time to mentor this summer if someone wants to do projects in this realm.
We have not updated the ideas page yet for this year so those could be adjusted. Off the top of my head here are some things that I think are priorities: - Finish and enhance the work of Sahil Shekhewat so that models can be built with body and joint specifications (unmerged GSOC work). - Finish and enhance the work of James Milam (jbm950) that adds a FeatherstoneMethod. This is one way to increase the computational efficiency. One thing that is missing are nice implementations of spatial vectors and their operators. - Finish and enhance the work of Nikhil Pappu. The Autolev parser needs to be battle tested on some examples and bugs worked out. We need the tests in the private gitlab repo to actually be run by SymPy. (merged, but not polished GSOC work). - The Linearizer class was updated by James Crist, but I think it is effectively broken for more complex problems. This needs to be fixed and we need examples of it working for systems with holonomic and nonholonomic constraints. - Improve symbolic computational speed. Hard examples need to be profiled and the Python implementations improved, work on the core differentiation algorithms to maximize speed, and ensure that optional dependencies on symengine function and help for hard problems. - Develop a more comprehensive set of examples. I've started creating more and migrating threse to the PyDy documentation: https://pydy.readthedocs.io/en/latest/#examples. One barrier to user adoption is the lack of examples that are clearly written that cover all types of dynamic systems. - I've recently discovered that for some problems the resulting symbolic equations are in a form that results in numerical error accumulation in the arithmetic. This is problematic and figuring out what this issue is and remedying it would be a nice improvement. - All of these PRs are hanging: https://github.com/sympy/sympy/pulls?q=is%3Aopen+is%3Apr+label%3Aphysics.mechanics and it would be nice to resolve them and get them merged. - If work can be done on PyDy, as has in the past, there are several things there too 1) support DAEs, 2) improve the visualizer in a number of ways, 3) migrate examples to jupyter-sphinx, etc. At this point, I'm generally in disfavor of proposing any new features or extensions to the library over fixing and improving what we already have. As you can see, we have several GSoC projects that were not fully polished off or were not merged at all.
