Present study consists the development of superficial neuromast and concentrates on the fabrication method and measurement system. Biomimetic flow sensor of this study consisted of single hair cell that attached perpendicular to subtract and strain gage was used as a sensing element. Simulation and experiment were done for various flow rates 0. 1 to 0. 5 m/s. Sensitivity of the sensor was obtained as 0. 26 mV/ms-1 based on the applied flow rate and output voltage. The experiment of moving object detection have been demonstrated where it enables to detect the moving object at close range 2 cm.

This paper presents an initial development stage of Fly Optimization Algorithm which will be used for the path planning system of a swarm of autonomous surface vehicles. This algorithm was initially designed to be implemented for a swarm of robots which would be able to locate the deepest portion of lakes. The ability of the robots to reach the designated target points will therefore also be considered. ©2010 IEEE.

This paper presents the initial developmental stage of mini Autonomous Surface Vehicles (ASVs), which is to define the algorithm of boundary navigation for each of the ASV via programming and sensor networks. To implement this, region recognition and several path planning algorithms have been utilized. Besides that, pixilation of path is also used to estimate the coverage of the path planning. The results from the experiment show that the Ĺvy flight algorithm is more suitable to be used compared to normal random. © 2010 IEEE.

Modeling of the novel microfluidic based flow sensor inspired from the canal neuromast in the fish lateral line system has been presented in this paper. The structure of the sensor consisted of the dome-shaped membrane and integrated with the microchannel which was filled with electrolyte. The analysis on the model was carried out using the computational fluid dynamic and finite element method. Based on the simulation, high performance of this sensor can be achieved by increasing the radius and decreasing the ratio of the radius of the dome-shaped membrane. The dome with 2.5 mm radius and 1.01 ratios was chosen due to the maximum response for the drag force and displacement based on the velocity input. The PDMS material which has lowers of Young Modulus was suggested to be used as a membrane. The microfluidic technology was proposed as a sensing element due to the simple structure and easy to be fabricated compare to the common sensing element such as piezoresistive and strain gage. The different electrolytes such as methanol, ethanol, water and propylene carbonate were simulated in order to study the effect of using different electrolytes to the performance of the microchannel. The methanol which has low viscosity and low surface tension was proposed to be used as an electrolyte for this sensor. © 2013 Penerbit UTM Press. All rights reserved.

This paper presents an initial development stage of mini Autonomous Surface Vehicles (ASVs). Due to the factors of complexity in instrument deployment, expensive tools for marine applications, time and resources consuming for data collections, swarming concept is proposed by using mini ASVs. This paper is focused upon the research and the early developmental stage of a Drosophila robot or DrosoBOT. Modification of the robots has been made based on the factors influencing the pre experimental deployment when tested at a swimming pool. ©2010 IEEE.

This paper examines the cooperative communication of multiple agents with no parent-child relation or hierarchy. In this communication framework, the multi agent communication must not be affected by the communication network failure between robots. Under this condition, a new communication framework was proposed which has allowed each agent to share the local information with reliable data delivery using peer to peer networking schemes. In this work, the whale communication call and echolocation concept were applied. The experimental results validated the communication reliability and performance. © 2014 Engineering and Technology Publishing.
