Active Clothing Material Perception using Tactile Sensing and Deep Learning
Humans represent and discriminate the objects in the same category using
their properties, and an intelligent robot should be able to do the same. In
this paper, we build a robot system that can autonomously perceive the object
properties through touch. We work on the common object category of clothing.
The robot moves under the guidance of an external Kinect sensor, and squeezes
the clothes with a GelSight tactile sensor, then it recognizes the 11
properties of the clothing according to the tactile data. Those properties
include the physical properties, like thickness, fuzziness, softness and
durability, and semantic properties, like wearing season and preferred washing
methods. We collect a dataset of 153 varied pieces of clothes, and conduct 6616
robot exploring iterations on them. To extract the useful information from the
high-dimensional sensory output, we applied Convolutional Neural Networks (CNN)
on the tactile data for recognizing the clothing properties, and on the Kinect
depth images for selecting exploration locations. Experiments show that using
the trained neural networks, the robot can autonomously explore the unknown
clothes and learn their properties. This work proposes a new framework for
active tactile perception system with vision-touch system, and has potential to
enable robots to help humans with varied clothing related housework.Comment: ICRA 2018 accepte
InViG: Benchmarking Interactive Visual Grounding with 500K Human-Robot Interactions
Ambiguity is ubiquitous in human communication. Previous approaches in
Human-Robot Interaction (HRI) have often relied on predefined interaction
templates, leading to reduced performance in realistic and open-ended
scenarios. To address these issues, we present a large-scale dataset, \invig,
for interactive visual grounding under language ambiguity. Our dataset
comprises over 520K images accompanied by open-ended goal-oriented
disambiguation dialogues, encompassing millions of object instances and
corresponding question-answer pairs. Leveraging the \invig dataset, we conduct
extensive studies and propose a set of baseline solutions for end-to-end
interactive visual disambiguation and grounding, achieving a 45.6\% success
rate during validation. To the best of our knowledge, the \invig dataset is the
first large-scale dataset for resolving open-ended interactive visual
grounding, presenting a practical yet highly challenging benchmark for
ambiguity-aware HRI. Codes and datasets are available at:

Non-meritocrats or conformist meritocrats? A redistribution experiment in China and France
Recent empirical evidence contends that meritocratic ideals are mainly a Western phenomenon. Intriguingly, the Chinese people appear to not differentiate between merit- and luck-based inequalities, despite their rich historical legacy of meritocratic institutions. We propose that this phenomenon might be due to the Chinese public’s greater adherence towards the status quo. In order to test this hypothesis, we run an incentivized redistribution experiment with elite university students in China and France, by varying the initial split of payoffs between two real-life workers to redistribute from. We show that Chinese respondents consistently and significantly choose more non-redistribution (playing the status quo) across both highly unequal and relatively equal status quo scenarios than our French respondents. Additionally, we also show that the Chinese sample does differentiate between merit- and luck-based inequalities, and does not redistribute less than the French absent status quo conformity. Ultimately, we contend that such a phenomenon is indicative of low political agency rather than apathy, inattention, or libertarian beliefs among the Chinese. Notably, our findings show that Chinese individuals’ conformity to the status quo is particularly pronounced among those from families of working-class and farming backgrounds, while it is conspicuously absent among individuals whose families have closer ties to the private sector
