The Faculty of Engineering at Victoria University of Wellington, in Collaboration with the New Zealand School of Music, has constructed a four-stringed modular robotic bass guitar, MechBass. This paper presents a systems overview of the instrument, focusing on the fretting mechanism, picking mechanism, actuator control electronics, and control software. Upon evaluation and testing, MechBass has...

This paper introduces a novel gear–clutch mechanism that takes advantage of the difference between the directions in the reaction forces that occur during meshing and jamming to ensure jam-free engagement of the gears. The proposed mechanism is a more compact advancement of the previously developed linear rack-tilting clutch used to provide a step change in the reduction ratio. Mathematical mod...

In this paper, a novel mechanism of remote actuation was proposed and its mechanical problems were discussed. This mechanism consists of leverage and parallelogram mechanism and transmits 3 d.o.f translational and 3 d.o.f rotational motions from the input to output. Such a remote actuation is significantly useful for robotic assist around MRI where the strong and precise magnet is used for imag...

The paper aims to analyze the kinematics of a three-degreeof-freedom (3-DOF) in-parallel actuated mechanism, which can be used as a wrist robotic device. Basic kinematic models are given. Due to symmetry in mechanism geometry, the input-output polynomial degree derived in position forward kinematics can be considerably reduced. By analyzing the relationship between the independent and dependent...

A novel category of humanoid robotic hands: COSA (Coupled and Self-Adaptive) hand is introduced in this paper. If a hand is called the COSA hand, which means that the fingers of the hand grasps objects with a special COSA grasping mode, which includes two processes, first is a coupled grasping process, then the second is a self-adaptive grasping process. The COSA grasping mode can take many adv...

Objectives: Pelvic lymphadenectomy is a crucial step in the management of different pelvic cancers for both prognostic and/or therapeutic goals. Robotic surgeries offered numerous benefits over open laparoscopic such as better visualization, shorter hospital stay, less pain and cosmoses. The aim this narrative review to evaluate value outcomes robotic lymph node dissection (PLND). Mechanism: Pu...

After the discovery of grid cells, which are an essential component to understand how the mammalian brain encodes spatial information, three main classes of computational models were proposed in order to explain their working principles. Amongst them, the one based on continuous attractor networks (CAN), is promising in terms of biological plausibility and suitable for robotic applications. How...

Recent advances in technology have led to the fusion of MIS techniques and robot devices. However, current systems are large and cumbersome. Optimizing the surgical robot mechanism will eventually lead to its integration into the operating room (OR) of the future becoming the extended presence of the surgeon and nurses in a room occupied by the patient alone. By optimizing a spherical mechanism...

In this manuscript, the reliability of a robotic system has been analyzed using the available data (containing vagueness, uncertainty, etc). Quantification of involved uncertainties is done through data fuzzification using triangular fuzzy numbers with known spreads as suggested by system experts. With fuzzified data, if the existing fuzzy lambda–tau (FLT) technique is employed, then the comput...
