Differentiable Spatial Planning using Transformers

The problem of path planning is usually solved with classical planning algorithms. A recent study on arXiv.org proposes a machine learning approach for this task. Transformers are used to capture the long-term spatial relationship. The idea of the Spatial Planning Transformers (SPT) consisting of attention heads that can attend to any part of the input is proposed. Spatial path planning ...

Light-powered soft robots could suck up oil spills

A floating, robotic film designed at UC Riverside could be trained to hoover oil spills at sea or remove contaminants from drinking water. Powered by light and fueled by water, the film could be deployed indefinitely to clean remote areas where recharging by other means would prove difficult.  Superimposed images showing Neusbot’s bending process.

Towards Robust and Adaptive Motion Forecasting: A Causal Representation Perspective

Motion forecasting is essential for autonomous systems. However, current methods struggle to discover the physical laws from data and are inefficient for knowledge transfer. A recent study on arXiv.org proposes to tackle these challenges from a causal representation perspective. Motion forecasting can be applied in different fields.

Learning Interactive Driving Policies via Data-driven Simulation

Intelligent agents can achieve complex continuous control and decision-making skills by learning representations from raw perception to high-level control actions. However, end-to-end policy learning is challenging for autonomous navigation as it is often limited to simplistic road environments, navigation with no interactions, or testing in solely passive settings.

Minimizing Energy Consumption Leads to the Emergence of Gaits in Legged Robots

Pre-programmed fixed gait patterns are used to achieve effective robotic locomotion. However, this approach limits the ability to perform general locomotion in diverse terrains and at different speeds. A recent paper shows that minimizing energy consumption plays a key role in the emergence of natural locomotion patterns in flat and complex terrains at different speeds. Legged robots are being developed ...

AI | Dialog Systems Part 2: How to Develop Dialog Systems That Make Sense

There is little argument that dialog systems are among the booming language-aware applications these days. Natural language interactions are quickly becoming a vital part of human daily lives by enabling us to access computational resources and engage in communications in the highly intuitive ways. In Part 1 of this series published here on technology.org, we presented dialog systems from the ...

VISTA 2.0: An Open, Data-driven Simulator for Multimodal Sensing and Policy Learning for Autonomous Vehicles

Simulations are an essential tool for advancing new algorithms in robot perception, learning, and evaluation. In the case of autonomous vehicles, experience in simulation is often significantly faster and safer than operation in the physical world. However, there exists a problem of scaling simulation engines to multiple sensor types. A driverless car. Image credit: Steve Jurvetson via Flickr, CC BY ...

Balancing Efficiency and Comfort in Robot-Assisted Bite Transfer

Assistive robot arms can help to provide care for those with disabilities. A recent paper on arXiv.org looks into robot-assisted feeding. A bite transfer strategy must optimize its trajectories on the fly by bringing food into a mouth without sacrificing user comfort. Eating. Image credit: bohed via Pixabay, free licence In order to achieve that, the researchers present a bite ...
