The company I work for is looking to build a package stacking robot, and in that regard we need a physics simulator that can accurately model the corresponding physics.
The packages consist of two different types, either cardboard boxes or soft polybags. Both of these types can come in pretty much any shape and hence are not just simple boxes.
For both of these types we will likely want to include some sort of deformation to keep things as realistic as possible, which as far as I understand involves including soft body physics.
Our main interest with such a simulation is to test stability of the placement as well as where we predict the package to end if it is dropped from a certain height and how it might deform the packages hit.
Currently we are looking into which physics simulator might the most viable to move forward with for the product we are developing. Isaacsim seems like a viable candidate since it fulfill most of our criteria, however while it does have soft body physics included it seems that previous users experience with the usage of this for cardboard packages have been unsatisfactory and resulted in non-realistic simulations. See here:
In that thread developers said that there were improvements underway for something like this and I’m wondering whether anyone could shed some light on these improvements.
- What exactly have been improved since the time of that thread?
- Does anyone have a demo of what a cardboard package simulation might look like with the physics engine now?
