grounding semantic categories in behavioral interactions: experiments with 100 objects

Author(s): Jivko Sinapov, Connor Schenck, Kerrick Staley, Vladimir Sukhoy, Alexander Stoytchev
Venue: Robotics and Autonomous Systems
Year Published: 2012
Keywords: visual perception, manipulation
Expert Opinion: Interactive perception and multimodal sensing are fundamental aspects of robotics and robot learning. The ability to execute actions to interact with the environment provides robots with a rich source of information, especially when combined with haptic, vision, and audio feedback. Grounding the object representations in the robot's actions provides the robot with representations that are not only well suited for future manipulation tasks, but that the robot can estimate through autonomous experimentation. The paper also touches on actively selecting actions to quickly reduce uncertainty.

affordances in psychology, neuroscience and robotics: a survey

Author(s): Lorenzo Jamone, Emre Ugur, Angelo Cangelosi, Luciano Fadiga, Alexandre Bernardino, Justus Piater and Jose Santos-Victor
Venue: IEEE Transactions on Cognitive and Developmental Systems
Year Published: 2018
Keywords: survey, visual perception, mobile robots, reinforcement learning
Expert Opinion: Affordances is an important term for robot learning, but also one that tends to be overloaded and can lead to confusion. If an object allows an agent to perform an action, then the object is said to afford the action to that agent. Affordances can generally be learned autonomously and are thus a fundamental aspect of self-supervised learning for autonomous robots. The nuances of the term however are still widely discussed in robotics and other fields. As a result, one should be aware of the ambiguity and different perspectives regarding the term when talking about affordances. This survey paper discusses some of the nuanced interpretations of the term affordances.

the cityscapes dataset for semantic urban scene understanding

Author(s): Marius Cordts, Mohamed Omran, Sebastian Ramos, Timo Rehfeld, Markus Enzweiler, Rodrigo Benenson, Uwe Franke, Stefan Roth, Bernt Schiele
Venue: IEEE Conference on Computer Vision and Pattern Recognition
Year Published: 2016
Keywords: visual perception, neural networks, mobile robots
Expert Opinion: Deep Learning has transformed the Robot Learning field completely in the last year. Whereas e.g. Computer Vision applications have access to large volumes of data (necessary to train DNNs), Robotics applications generally suffer from the problem of collecting enough data for learning tasks. The KITTI dataset is one example of a great effort to provide relevant data for Robot (or autonomous vehicle) Learning.

Author(s): Nikolaus Mayer, Eddy Ilg, Philip Hausser, Philipp Fischer, Daniel Cremers, Alexey Dosovitskiy, Thomas Brox
Venue: IEEE Conference on Computer Vision and Pattern Recognition
Year Published: 2015
Keywords: state estimation, neural networks, visual perception
Expert Opinion: Deep Learning has transformed the Robot Learning field completely in the last year. Whereas e.g. Computer Vision applications have access to large volumes of data (necessary to train DNNs), Robotics applications generally suffer from the problem of collecting enough data for learning tasks. A very useful approach is to generate synthetic data. The FlowNet dataset is such an example.

assessing grasp stability based on learning and haptic data

Author(s): Yasemin Bekiroglu, Janne Laaksonen, Jimmy Alison Jurgensen, Ville Kyrki and Danica Kragic
Venue: IEEE Transactions on Robotics
Year Published: 2011
Keywords: manipulation, visual perception, contact dynamics
Expert Opinion: "Learning to grasp" can actually imply a lot of different learning problems. We often think about grasp synthesis, i.e., the problem of determining where to place the hand to achieve a stable grasp (I strongly recommend reading Data-Driven Grasp Synthesis- a Survey for more on this topic). This paper focuses on the important problem of using multiple sensor modalities to determine if an executed grasp attempt resulted in a stable grasp. As robot learning researchers, it is important to consider how problems can be approached from different directions and how different information sources can be incorporated and change the problem. One should also think about robustness and consider how learning factors into monitoring skill executions for errors.

adaptive representation of dynamics during learning a motor task

Author(s): Reza Shadmehr and Ferdinando A. Mussa-lvaldi
Venue: The Journal of Neuroscience
Year Published: 1994
Keywords: dynamical systems, visual perception, planning
Expert Opinion: The reason why I picked these articles and books is because I think that robot learning cannot be separated from the cognitive architecture supporting the learning processes. The first two reference highlight the importance and role of embodiment (in humans and robots) and the fact that in physical systems part of the learning process is embedded in the morphology and material.

square root sam: simultaneous localization and mapping via square root information smoothing

Author(s): Frank Dellaert, Michael Kaess
Venue: Intl. J. of Robotics Research
Year Published: 2006
Keywords: manipulation, planning, mobile robots, state estimation, visual perception, probabilistic models
Expert Opinion: This paper, as well as the follow up iSAM2 paper, focuses on treating localization and mapping problems as nonlinear least squares and then optimizing as efficiently as possible. This is a powerful technique that serves as the backbone for many SAM solvers, and, can be applied more generally to all sorts of inference problems in robotics. Techniques building on this work have been used in planning, manipulation, and control.
