Towards the role of humanoid robots as squad mates in urban operations and other domains, we identified doors as a major area lacking capability development. In this paper, we focus on the ability of humanoid robots to navigate and deal with doors. Human-sized doors are ubiquitous in many environment domains and the humanoid form factor is uniquely suited to operate and traverse them. We present an architecture which incorporates GPU accelerated perception and a tree based interactive behavior coordination system with a whole body motion and walking controller. Our system is capable of performing door traversals on a variety of door types. It supports rapid authoring of behaviors for unseen door types and techniques to achieve re-usability of those authored behaviors. The behaviors are modelled using trees and feature logical reactivity and action sequences that can be executed with layered concurrency to increase speed. Primitive actions are built on top of our existing whole body controller which supports manipulation while walking. We include a perception system using both neural networks and classical computer vision for door mechanism detection outside of the lab environment. We present operator-robot interdependence analysis charts to explore how human cognition is combined with artificial intelligence to produce complex robot behavior. Finally, we present and discuss real robot performances of fast door traversals on our Nadia humanoid robot. Videos online at https://www.youtube.com/playlist?list=PLXuyT8w3JVgMPaB5nWNRNHtqzRK8i68dy.
Learning to Open and Traverse Doors with a Legged Manipulator
Zhang, Mike, Ma, Yuntao, Miki, Takahiro, Hutter, Marco
Using doors is a longstanding challenge in robotics and is of significant practical interest in giving robots greater access to human-centric spaces. The task is challenging due to the need for online adaptation to varying door properties and precise control in manipulating the door panel and navigating through the confined doorway. To address this, we propose a learning-based controller for a legged manipulator to open and traverse through doors. The controller is trained using a teacher-student approach in simulation to learn robust task behaviors as well as estimate crucial door properties during the interaction. Unlike previous works, our approach is a single control policy that can handle both push and pull doors through learned behaviour which infers the opening direction during deployment without prior knowledge. The policy was deployed on the ANYmal legged robot with an arm and achieved a success rate of 95.0% in repeated trials conducted in an experimental setting. Additional experiments validate the policy's effectiveness and robustness to various doors and disturbances. A video overview of the method and experiments can be found at youtu.be/tQDZXN_k5NU.
Is this the friendliest car yet? Toyota unveils its driverless Concept-I which comes with 'Yui' - an AI assistant that learns your preferences
The vehicle is Toyota's Concept-I car, and it claims to represent a friendlier, people-focused approach to future mobility. While the car is only a concept and is not on sale, it gives a glimpse into the firm's vision for the future of automobiles. The vehicle is Toyota's Concept-i car, that represents a friendlier, people-focused appraoch to future mobility The Concept-I was unveiled at the CES technology show in Las Vegas, and was produced by the firm's CALTY design centre in California. The basic philosophy for the design is'kinetic warmth' - the belief that mobility technology should be warm, welcoming and fun. Bob Carter, Senior Vice President of Automotive Operations at Toyota, said: 'At Toyota we recognise that the important question isn't whether future vehicles will be equipped with automated or connected technologies, it is the experience of the people who engage with those vehicles. 'Thanks to Concept-i and the power of artificial intelligence, we think the future is a vehicle that can engage with people in return.'
