This results in a perception model that localizes objects from the first real tactile observation.
In this paper, we present an approach to tactile pose estimation from the first touch for known objects.
Adding auxiliary losses to the main objective function is a general way of encoding biases that can help networks learn better representations.
In this paper, we tackle the generalization problem via fast adaptation, where we train a prediction model to quickly adapt to the observed visual dynamics of a novel object.
Such models, however, are approximate, which limits their applicability.
This work studies the problem of shape reconstruction and object localization using a vision-based tactile sensor, GelSlim.
We explore the use of graph neural networks (GNNs) to model spatial processes in which there is no a priori graphical structure.
Physics engines play an important role in robot planning and control; however, many real-world control problems involve complex contact dynamics that cannot be characterized analytically.
Modular meta-learning is a new framework that generalizes to unseen datasets by combining a small set of neural modules in different ways.
An efficient, generalizable physical simulator with universal uncertainty estimates has wide applications in robot state estimation, planning, and control.
Decades of research in control theory have shown that simple controllers, when provided with timely feedback, can control complex systems.

Since product images are readily available for a wide range of objects (e. g., from the web), the system works out-of-the-box for novel objects without requiring any additional training data.
On the other hand, it achieves effective sampling and accurate probabilistic propagation by relying on the GP form of the system, and the sum-of-Gaussian form of the belief.
This paper presents a data-driven approach to model planar pushing interaction to predict both the most likely outcome of a push and its expected variability.
