Recently, flexible needles with bevel tips for percutaneous intervention have attracted significant interest. However, there are remaining problems related to controlling by duty-cycle algorithm which prevents widespread adoption of this technology. This motivates development of a new steerable flexible needle model that can change its curvature without axial rotation. In this paper, we propose a...
This paper presents a novel application based on the bio-inspired motion of the Amoeba. This research is focused on development a soft micro robot based on the Amoeba locomotion which can be named Whole Skin Locomotion. The robot is created using the fluid filled toroid method that acts as a body shaping feature with ferrofluid material placed within that is delivered to create the driving force....
For the actuation of a swimming microrobot, various types of electromagnetic actuation (EMA) systems were proposed. Compared with a conventional actuation system using an electric motor or shape memory alloy (SMA), EMA system has many advantages for a wireless actuation of a microrobot. This paper introduces a biomimetic swimming tadpole microrobot. The developed microrobot could be driven by an external...
The purpose of this paper is to introduce a new generation of micro-robots utilizing electromagnetic actuation (EMA) systems technology. The fundamental principles and characteristics of EMA systems are presented in order to facilitate understanding of the technology. The proposed micro-robots using EMA systems are categorized as 1) micro-robots actuated by the gradient magnetic field of EMA systems...
For the actuation of mini-robots, electromagnetic based actuation (EMA) methods were proposed. EMA system has many advantages for the wireless actuation of mini-robots. This paper introduces our proposed biomimetic swimming mini-robots such as tadpole robot and jellyfish robot. The biomimetic swimming mini-robots could be driven by an external alternating magnet field using three pairs of Helmholtz...
Shape is one of the useful information for object detection. The human visual system can often recognize objects based on the 2-D outline shape alone. In this paper, we address the challenging problem of shape matching in the presence of complex background clutter and occlusion. To this end, we propose a graph-based approach for shape matching. Unlike prior methods which measure the shape similarity...
In recent years, several surgical or assistant robots have made a successful debut to surgical theatre. Due to their large size, and high price, there is a growing need for the miniaturization of these surgical robots. In this paper, a design methodology for a compact surgical robot is presented. Considering workspace and force requirements, a simulation and experiments are conducted to determine...
