Rethinking Trust in Social Robotics

How soon do you think you will encounter an autonomous robot in your day-to-day life?  The question of trust between robots and humans will have to become the basis of the entire social robotics. Image credit: epSos.de via Wikimedia (CC BY 2.0) If your answer was not “never”, you probably expect human-robot interaction to start happening soon & its frequency ...

One giant leap for the mini cheetah

A new control system, demonstrated using MIT’s robotic mini cheetah, enables four-legged robots to jump across uneven terrain in real-time. A loping cheetah dashes across a rolling field, bounding over sudden gaps in the rugged terrain. The movement may look effortless, but getting a robot to move this way is an altogether different prospect. In recent years, four-legged robots inspired ...

OPEn: An Open-ended Physics Environment for Learning Without a Task

Reinforcement learning algorithms are commonly used for narrowly defined tasks. In contrast, humans plan their actions using a mental model of the world’s physical structure. Inspired by human intelligence, a recent paper proposes an environment that is designed as a sandbox where the agent has to learn about how a physical world works. Illustration of the problem setup for modeling ...

How Bodies Get Smarts: Simulating the Evolution of Embodied Intelligence

An in silico playground for creatures that learn, mutate, and evolve establishes the importance of morphological intelligence and suggests a new way to optimize embodied AIs. Animals have embodied smarts: They perform tasks that their bodies are well designed for. That’s because the intelligence of every animal species evolved in tandem with its physical form as it interacted with its ...

Virtual fitting room

An AI-driven imaging system allows users to try on virtual outfits in real time. A team of researchers have created a way for people to visualize themselves wearing items of clothing they don’t have direct physical access to. The virtual try-on system uses a unique capture device and an artificial intelligence (AI)-driven way to digitize items of clothing. Using a ...

Flying High-Speed Drones into the Unknown with AI

Researchers at the University of Zurich have developed a new approach to autonomously fly quadrotors through unknown, complex environments at high speeds using only on-board sensing and computation. The new approach could be useful in emergencies, on construction sites or for security applications. When it comes to exploring complex and unknown environments such as forests, buildings or caves, drones are ...

Perseverance Sees Evidence of Flash Floods in Jezero Crater

Nearly eight months into the Perseverance rover’s mission on Mars, researchers have confirmed that Jezero crater is (as was believed) an ancient lakebed, but more significantly, that it once experienced powerful flash floods that pushed boulders from tens of miles upstream into the crater basin. Years before Perseverance ever left Earth, orbital photographs of Jezero crater showed what looked to ...

Focus on Impact: Indoor Exploration with Intrinsic Motivation

Robotic exploration is the task of autonomously navigating an unknown environment to gather sufficient information to represent it. Usually, deep reinforcement learning-based algorithms are employed, and extrinsic rewards based on occupancy anticipation are used in training. However, such rewards require knowledge about the precise layout of the training environments, which is expensive to gather. Therefore, a recent paper proposes to ...
