Middle ear surgery involves the smallest and the most fragile bones of the human body. Since microsurgical gestures and a submillimetric precision are required in these procedures, the outcome can be potentially improved by robotic assistance. Today, there is no commercially available device in this field. Here, we describe a method to design a teleoperated assistance robotic system dedicated t...

Compliance in robotic systems has been exploited to allow rigid mechanisms to come into contact with complex and possibly fragile objects. By incorporating compliance and instrumentation into a single device nearby objects can be detected before direct contact occurs. That way, safer and smoother robot guidance can be achieved both while approaching and while touching surfaces. Furthermore, the...

Autonomous robotic devices are vital to the peformance of space mission. These range from smart servo-controlled devices (e.g., an antenna or a camera) to autonomous mobile robots (e.g., planetary rovers) to future interactive astronaut assistants. Each robotic device operates in its specific environment, which is usually not fully predictable and not fully observable, and which may include hum...

Robotic operations performed in earth orbit face unique challenges. In the case of the Special Purpose Dexterous Manipulator (SPDM), a two-armed robotic device, operations can last multiple orbital days, with dynamic sunlit days and very dark nights. Direct and indirect visibility can be difficult. This project developed and tested the use of augmented reality technology with a ground based tra...

1 P.G. Student 2 Associater Professor 1,2 Department of Electronics & Communication Engineering 1,2 MMMUT Gorakhpur, U.P., India-273010 Abstract— Sensor plays an important role in robotics. Sensors are used to determine the current state of the system. Robotic applications demand sensors with high degrees of repeatability, precision, and reliability. Flex sensor is such a device, which accompli...

Flapping-wing robotic platforms based on Dipteran insects have demonstrated lift to weight ratios greater than 1, but research into regulating the aerodynamic forces produced by their wings has largely focused on active wing trajectory control. In an alternate approach, a flapping-wing drivetrain design that passively balances aerodynamic drag torques is presented. A discussion of the dynamic p...

Robotic assistance is one of the latest additions to the field of laparoscopic surgery. The most commonly used robotic device in Urology is the da Vinci(®) system of which over 200 devices are installed worldwide including 3 in India. This robot consists of three or four arms, one of which is used to hold and manipulate the laparoscopic camera while the others are used to manipulate specialized...

The paper discusses the background and major motivations which are driving the AuRoRA (Autonomous Robotic platform as a Remedial tool for children with Autism) research project. We argue that mobile robot technology can be used in a useful and scientifically challenging application area, namely the rehabilitation of children with autism. Initial steps of the development of a robotic platform as...

In this paper we describe a set of algorithms and a novel miniature device that together can autonomously position electrodes in neural tissue to obtain high-quality extracellular recordings. This robotic system moves each electrode to detect the signals of individual neurons, optimize the signal quality of a target neuron, and then maintain this signal over time. Such neuronal signals provide ...

Engineers are often inspired by the behavioral flexibility and robustness seen in nature. Recent advances in tissue engineering now allow the use of organic components in robotic applications. By integrating organic and synthetic components, researchers are moving toward the development of engineered organisms whose structural framework, actuation, sensing, and control are partially or complete...
