Human-Robot Cooperation for Surface Repair Combining Automatic and Manual Modes
2020
[EN] This article develops a human-robot cooperation to carry out treatments such as sanding, polishing, etc. on the surface of a known rigid object. For this purpose, a vision system is considered to get the object location to ensure not only the perpendicularity of the obot tool to the object surface but also a smooth approach of the tool to the surface. In order to add flexibility, the proposal includes the simultaneous combination of automatic and manual modes of operation. Thus, the human user can guide the robot tool to treat arbitrary areas (manual mode) and, when the operator releases the tool, the robot goes into the automatic mode to treat prior established areas. The method uses …
Robotic-Assisted Neck Dissection: Our Experience
2021
Abstract Introduction Robotic neck dissection surgery allows less invasiveness to significantly improve the aesthetic impact even though it does not compromise the principles of radical cancer procedure. Objective The aim of our work is to describe our personal experience with robotic neck dissection surgery. Methods A retrospective study was conducted by analyzing 10 patients subjected to a robotic neck dissection surgery. In the period from August 2012 to December 2018, these patients have been treated exclusively with robotic lateral-cervical dissection. Five of them were subjected to robotic-assisted transaxillary neck dissection (RATAND) and the other 5 treated with robotic-assisted re…
Robotics and automation for societal good : global South challenges and technology-policy considerations
2018
Robotics and automation and artificial intelligence technologies hold immense potential in addressing many of the societal challenges as exemplified in the sustainable development goals of the 2030 agenda of the United Nations. They have the potential not only to increase the standard of living in developed countries, but to improve the quality of life in the so-called «Global South». This article discusses underlying challenges and technology-policy considerations when deploying emerging technologies in developing and developed economies. Various examples and implementations in collaboration with humanitarians, researchers and developers, and professional organizations across the globe are…
The Sound of Swarm. Auditory Description of Swarm Robotic Movements
2023
Movements of robots in a swarm can be mapped to sounds, highlighting the group behavior through the coordinated and simultaneous variations of musical parameters across time. The vice versa is also possible: sound parameters can be mapped to robotic motion parameters, giving instructions through sound. In this article, we first develop a theoretical framework to relate musical parameters such as pitch, timbre, loudness, and articulation (for each time) with robotic parameters such as position, identity, motor status, and sensor status. We propose a definition of musical spaces as Hilbert spaces, and musical paths between parameters as elements of bigroupoids, generalizing existing conceptio…
Design and prototyping of a magnetic actuator based permanent magnets for microbead navigation in viscous environment
2017
International audience; For actuating the magnetic microrobots, two types of magnetic actuation technologies have been used during the last past years. These magnetic technologies may be either electromagnetic coils or permanent magnets based systems. This second solution is not the most used by researchers, because of the difficulties to control the magnetic force. In this paper we propose a magnetic actuator prototype based on permanent magnets. In addition to the magnets, the actuator is also composed of a mechanical structure. This structure is used for positioning the permanent magnets, which allows to control the magnetic force generated by the actuator. We demonstrated in simulation …
Considerations Concerning a Methodology for Musical Robotics and Human-Robot Interaction
2009
Robot technology is increasingly employed in artistic (musical) applications and as modeling tool for the investigation of general cognitive abilities and music related behavior in particular. Apart from the specifications of required system behavior and technological aspects of system design/implementation, problems occur concerning the evaluation of the systems. In recent approaches, techniques such as collecting informal reports, perceptual tests, video-based observational studies, or rating scales have been employed. Questions arise, however, as to the reliability and validity of these measures, and the lack of standardization diminishes the comparability of different studies. To attack…
A Neural Multi-Agent Architecture for an Autonomous Mobile Robot Control
1999
The aim of this paper is to introduce a multi-agent architecture for an autonomous robot control oriented to obtain high design modularity and high parallelism of decision processes. A multi-agent approach allows us to design several specialized agents and each of them is optimized in order to solve a single part of the whole task. Each agent is able to cooperate with other agent exchanging information, so the robot is able to make the appropriate policy of management to reach a prefixed goal. We tested the proposed architecture with a simple application: an autonomous mobile robot performs object retrieval tasks into unknown structured environments. The robot is not given a priori map of t…
Mainz Rolling Brains 2000
2001
The team Mainz Rolling Brains participated in RoboCup world championships for the third time this year. The team is based on the improved technical level from last year but has a completly new decision level. The latter level was modularized and we introduced communication for world model and tactical information.
Design and Simulation of a Vision-Based Automatic Trout Fish-Processing Robot
2021
Today, industrial automation is being applied in a wide range of fields. The initial modeling of robots and mechanical systems together with simulation results in optimal systems. In this study, the designed system is simulated to obtain the required velocities, accelerations and torques of the actuating arms in a vision-based automatic system. Due to the slippery skin of fish and the low friction coefficient, it is not easy to design an optimal tool to handle fish. Since the fish-processing operation is undertaken step by step and provides fish stability, it is essential that the gripper enables different processing operations along the system. The proposed system performs belly-cutting, b…
Tehno-intimitāte mūsdienu Japānas sabiedrībā
2016
Japāna jau ilgu laiku ir zināma kā zeme, kurā tehnika ieņem nozīmīgu lomu sabiedrības ikdienā. Edo periodā meistari darināja karakuri mehāniskās lelles, kas tiek uzskatītas par robotu priekštečiem. Pēc Edo perioda modernizācijā un robotos Japānas sabiedrība saskatīja atbildi vairākām problēmām, gan ekonomiskās, gan sociālām. Mūsdienās roboti ir blakus cilvēkiem un lēnām kļūst par daļu no sabiedrības. Līdz kā tehnika sāk ieņemt jaunu lomu, sabiedrības attiecības ar to mainās. No utilitārim rīkiem izdzīvošanai, tehnika kļūst par draugu, kompanjonu, kas beigās noved pie tehno-intimitātes izveidošanās. Ar vārdu “intīms” parasti apraksta saikni starp cilvēkiem, bet mūsdienās tas tiek izmantots a…
