A Soft Body Physics Simulator with Computational Offloading to the Cloud [PDF]
Information, 2018 We describe the gamification of a soft physics simulator. We developed a game, called Jelly Dude, that allows the player to change and modify the game engine by tinkering with various physics parameters, creating custom game levels and installing scripts.

Implicit Physics-aware Policy for Dynamic Manipulation of Rigid Objects via Soft Body Tools
2025 IEEE International Conference on Robotics and Automation (ICRA)Recent advancements in robot tool use have unlocked their usage for novel tasks, yet the predominant focus is on rigid-body tools, while the investigation of soft-body tools and their dynamic interaction with rigid bodies remains unexplored. This paper takes a pioneering step towards dynamic one-shot soft tool use for manipulating rigid objects, a ...

Differentiable Implicit Soft-Body Physics
CoRR, 2021 We present a differentiable soft-body physics simulator that can be composed with neural networks as a differentiable layer. In contrast to other differentiable physics approaches that use explicit forward models to define state transitions, we focus on implicit state transitions defined via function minimization.

PlasticineLab: A Soft-Body Manipulation Benchmark with Differentiable Physics
CoRR, 2021 Simulated virtual environments serve as one of the main driving forces behind developing and evaluating skill learning algorithms. However, existing environments typically only simulate rigid body physics. Additionally, the simulation process usually does not provide gradients that might be useful for planning and control optimizations.

Implicit neural representation for physics-driven actuated soft bodies
ACM Transactions on Graphics, 2022 Active soft bodies can affect their shape through an internal actuation mechanism that induces a deformation. Similar to recent work, this paper utilizes a differentiable, quasi-static, and physics-based simulation layer to optimize for actuation signals parameterized by neural networks.
