With lowering of the elastic modulus, CDC–POM–PPy composite shows a 20× improved strain response over PPy/DBS.
Teleoperated mobile robots, equipped with object manipulation capabilities, provide safe means for executing dangerous tasks in hazardous environments without putting humans at risk. However, mainly due to a communication delay, complex operator interfaces and insufficient Situational Awareness (SA), the task productivity of telerobots remains inferior human workers. This paper addresses shortcomings by proposing combined approach (i) scalable intuitive interface gestural verbal input, (ii)...
Large language models (LLM) are now the de facto task planners for Embodied AI (EAI) systems. This shift can be attributed to LLMs' powerful, emergent properties which enable their adaptation downstream tasks with minimal no fine tuning via prompting. However, we find that LLM-driven planning is not a solved problem. In this work measure extent these adapted complex and domain-specific few-shot Additionally, contribute quantitative qualitative analysis on prompt robustness. Lastly, meet...
To facilitate continuous development of novel HRI systems, it is beneficial to have tools that enable quick adjustments, flexibility, or re-invention the human interfaces when system requirements change due updates in state-of-the-art, application domain, etc. Thus, modularity a key design principle which promotes software reuse and scalability, reduces time cost. Hence, robot’s autonomous capabilities should not depend on command interface be decoupled via common format possesses...
For widespread deployment of robots in challenging environments (fire fighting, search and rescue, planetary exploration, etc), the software robot must allow for reliability adaptability. many existing systems, an unexpected change mission specification, component failures, or energy conservation requires downtime adaption (redesign logic, switching sensor data processing pipeline, etc.). This is because hardware components robotic applications are commonly chosen designed based on task...
In hospitals, trained medical staff are often, in addition to performing complex procedures, spending valuable time on secondary tasks such as transporting samples and equipment; or even guiding patients visitors around the premises. If these non-medical were automated by deploying mobile service robots, more can be focused treating allowing well-deserved rest for potentially overworked healthcare professionals. Automating requires a human-aware robotic mobility system that among other...
One of the main difficulties in teleoperated systems is providing an operator with sufficient Situational Awareness (SA). This paper introduces three open-source packages that improve operator's SA using Robot Operating System (ROS). The first package-rviz_textured_sphere-allows rendering panospheric camera outputs as spherical images ROS visualization software RViz. A system where this data virtual reality (OSVR) headset framework achieved second package: rviz_plugin_osvr. Finally, third...
Free standing conducting polymer films based on polypyrrole doped with dodecylbenzoesulfate (PPyDBS) are investigated in TBACF3SO3 (tetrabutylammonium trifluoromethanesulfonate) propylene carbonate (PC-Tf) followed aqueous TMACl tetramethylammonium chloride (Aq-TM) the aim to investigate actuation properties (anion or cation-driven actuation). Under isometric (constant force) conditions ECMD (electro-chemo-mechanical deformation) measurements performed during cyclic voltammetric and...
Conducting polymer linear actuators, for example sodium dodecylbenzenesulfonate (NaDBS) doped polypyrrole (PPy/DBS), have shown moderate strain and stress. The goal of this work was to increase the obtainable stress by adding additional active material PPy/DBS. In recent year's carbide-derived carbon (CDC)-based materials been applied in actuators; however, obtained displacement actuation speed has low comparing conducting based actuators. present work, a CDC-PPy hybrid synthesized...
Recent advances in generative modeling have spurred a resurgence the field of Embodied Artificial Intelligence (EAI). EAI systems typically deploy large language models to physical capable interacting with their environment. In our exploration for industrial domains, we successfully demonstrate feasibility co-located, human-robot teaming. Specifically, construct an experiment where Augmented Reality (AR) headset mediates information exchange between agent and human operator variety...
Objective This study investigates the effect of naturalistic visual cues on human avoidance behavior for a potential use in telerobotic user interfaces incorporating mixed-reality environments (e.g., augmented reality). Background Telerobotic systems used hazardous require that draw operators’ attention to dangers. Existing means hazard notification can often distract or induce stress operators. In design and implementation such interfaces, semiotics plays critical role creating more...
