Differentiable and Learnable Robot Models

Building differentiable simulations of physical processes has recently received an increasing amount of attention. Specifically, some efforts develop differentiable robotic physics engines motivated by the computational benefits of merging rigid body simulations with modern differentiable machine learning libraries. Here, we present a library that focuses on the ability to combine data driven methods with analytical rigid body computations. More concretely, our library Differentiable Robot Models implements both differentiable and learnable models of the kinematics and dynamics of robots in Pytorch.
