Visual learning in Drosophila: Application on a roving robot and comparisons
2011
Visual learning is an important aspect of fly life. Flies are able to extract visual cues from objects, like colors, vertical and horizontal distributedness, and others, that can be used for learning to associate a meaning to specific features (i.e. a reward or a punishment). Interesting biological experiments show trained stationary flying flies avoiding flying towards specific visual objects, appearing on the surrounding environment. Wild-type flies effectively learn to avoid those objects but this is not the case for the learning mutant rutabaga defective in the cyclic AMP dependent pathway for plasticity. A bio-inspired architecture has been proposed to model the fly behavior and experi…
Experiments in Artificial Theory of Mind: From Safety to Story-Telling
2018
Theory of mind is the term given by philosophers and psychologists for the ability to form a predictive model of self and others. In this paper we focus on synthetic models of theory of mind. We contend firstly that such models—especially when tested experimentally—can provide useful insights into cognition, and secondly that artificial theory of mind can provide intelligent robots with powerful new capabilities, in particular social intelligence for human-robot interaction. This paper advances the hypothesis that simulation-based internal models offer a powerful and realisable, theory-driven basis for artificial theory of mind. Proposed as a computational model of the simulation theory of …
Robots responding to care needs? : A multitasking care robot pursued for 25 years, available products offer simple entertainment and instrumental ass…
2020
Twenty-five years ago, robotics guru Joseph Engelberger had a mission to motivate research teams all over the world to design the ‘Elderly Care Giver’, a multitasking personal robot assistant for everyday care needs in old age. In this article, we discuss how this vision of omnipotent care robots has influenced the design strategies of care robotics, the development of R&D initiatives and ethics research on use of care robots. Despite the expectations of robots revolutionizing care of older people, the role of robots in human care has remained marginal. The value of world trade in service robots, including care robots, is rather small. We argue that the implementation of robots in care is n…
Psiholoģiskās ietekmēšanas paņēmienu izmantošana seriālā "Mr. Robot", to ietekme uz uzvedību un uztveri dažādās auditorijās
2018
Bakalaura darba “Psiholoģiskās ietekmēšanas paņēmienu izmantošana seriālā “Mr. Robot”, to ietekme uz uzvedību un uztveri dažādās auditorijās” mērķis ir noskaidrot, vai un ar kādiem paņēmieniem seriāls “Mr. Robot” ietekmē cilvēku, tā domāšanu un uzvedību. Teorētiskajā daļā tiek apskatīts, kā darbojas cilvēka uztvere, mediju satura ietekme uz skatītāju un efekti, ko var izraisīt seriāli, kā arī veikts ieskats televīzijas seriāla žanra raksturojumā. Ar semiotisko analīzi, eksperimentu un interviju noskaidrots, kādi paņēmieni tiek izmantoti seriālā “Mr.Robot”, vai un ar kādiem paņēmieniem seriāls ietekmē auditoriju, kā arī tas, vai šo auditorijas ietekmēšanas paņēmienu rezultātā skatītājs tiek …
Social Robots and Human Touch in Care : The Perceived Usefulness of Robot Assistance Among Healthcare Professionals
2019
Touching in care work is inevitable, particularly in cases where clients depend on nurses for many activities of daily living, such as bathing, dressing, lifting and assisting. When new technologies are involved in nurse–client relationships, the significance of human touch needs special attention. Stressing the importance of practitioners’ opinions on the usage of robots in care environments, we analyze care workers’ attitudes toward robot assistance in the care of older people and reflect on their ideas of the embodied relationship that caregivers and care receivers have with technology. To examine nurses’ attitudes toward care robots, we use survey data on professional care workers (n = …
Humanoid Cognitive Robots That Learn by Imitating: Implications for Consciousness Studies.
2018
While the concept of a conscious machine is intriguing, producing such a machine remains controversial and challenging. Here we describe how our work on creating a humanoid cognitive robot that learns to perform tasks via imitation learning relates to this issue. Our discussion is divided into three parts. First, we summarize our previously-detailed framework for advancing the understanding of the nature of phenomenal consciousness. This framework is based on identifying computational correlates of consciousness. Second, we describe a cognitive robotic system that we recently developed that learns to perform tasks by imitating human-provided demonstrations. This humanoid robot uses cause-ef…
Beyond Sentinel Lymph Node: Outcomes of Indocyanine Green-Guided Pelvic Lymphadenectomy in Endometrial and Cervical Cancer
2023
Background: The aim of our study was to compare the number of lymph nodes removed during indocyanine green (ICG)-guided laparoscopic/robotic pelvic lymphadenectomy with standard systematic lymphadenectomy in endometrial cancer (EC) and cervical cancer (CC). Methods: This is a multicenter retrospective comparative study (Clinical Trial ID: NCT04246580; updated on 31 January 2023). Women affected by EC and CC who underwent laparoscopic/robotic systematic pelvic lymphadenectomy, with (cases) or without (controls) the use of ICG tracer injection within the uterine cervix, were included in the study. Results: The two groups were homogeneous for age (p = 0.08), Body Mass Index, International Fede…
Dziļās stimulētās mācīšanās izmantošana industriālu robotu vadīšanā
2022
Dziļā stimulētā mācīšanās ir guvusi plašus panākumus dažādās jomās, kā, piemēram, videospēlēs un galda spēlēs. Robotikas kontroles jomā stimulētās mācīšanās algoritmi dod cerību, ka robotiem būs cilvēkam līdzīgas spējas – mācīties caur izmēģinājumiem un kļūdām. Šajā darbā tiks pētīta dziļās stimulētās mācīšanās pielietošana robotikas manipulācijām, kā arī tiks izveidota jauna dziļās stimulētās mācīšanās vide simulatorā “Ignition Gazebo”. Praktiskā uzdevuma mērķis ir izveidot unikālu, reālistisku stimulētas mācīšanās vidi dažādiem robotikas uzdevumiem, kas varētu tikt izmantota kā sākotnējs paraugs, sarežģītām reālās dzīves scenāriju simulācijas izveidei.
An ACT-R Based Humanoid Social Robot to Manage Storytelling Activities
2020
This paper describes an interactive storytelling system, accessible through the SoftBank robotic platforms NAO and Pepper. The main contribution consists of the interpretation of the story characters by humanoid robots, obtained through the definition of appropriate cognitive models, relying on the ACT-R cognitive architecture. The reasoning processes leading to the story evolution are based on the represented knowledge and the suggestions of the listener in critical points of the story. They are disclosed during the narration, to make clear the dynamics of the story and the feelings of the characters. We analyzed the impact of such externalization of the internal status of the characters t…
Prediction of significant renal function decline after open, laparoscopic, and robotic partial nephrectomy: External validation of the Martini’s nomo…
2022
Objectives: Martini et al. developed a nomogram to predict significant (>25%) renal function loss after robot-assisted partial nephrectomy and identified four risk categories. We aimed to externally validate Martini’s nomogram on a large, national, multi-institutional data set including open, laparoscopic, and robot-assisted partial nephrectomy. Methods: Data of 2584 patients treated with partial nephrectomy for renal masses at 26 urological Italian centers (RECORD2 project) were collected. Renal function was assessed at baseline, on third postoperative day, and then at 6, 12, 24, and 48 months postoperatively. Multivariable models accounting for variables included in the Martini’s nomog…
