Many animals, including insects, successfully engage in visual homing. We describe a system that allows a mobile robot to home. Specifically, we propose a simple, yet robust, homing scheme that only relies upon the observation of the bearings of visible landmarks. However, this can easily be extended to include other visual cues. The homing algorithm allows a mobile robot to home incrementally ...

In this paper, we propose a modular approach to decompose the fish movement into several basic behaviours, namely straight cruise, cruise in turn and sharp turn, to mimic carangiform swimming of a real fish. To test these behaviours, a robotic fish is designed and built at Essex. It has 6 joints (R/C servo motors) and controlled by an efficiency control method. The experimental results show its...

In the “modified quasi-steady” approach, two-dimensional (2D) aerodynamic models of flapping wing motions are analyzed with focus on different types of wing rotation and different positions of rotation axis to explain the force peak at the end of each half stroke. In this model, an additional velocity of the mid chord position due to rotation is superimposed on the translational relative veloci...

Louisiana Tech University has recently developed a curriculum (NASA-Threads) that integrates engineering, mathematics, and physics. The curriculum, which targets junior and senior high school students, uses hands-on projects that develop student ability to solve realistic multiple-step problems and bring excitement into the classroom. NASA-Threads integrates NASA applications, fundamentals, tec...

Indonesia is a potential area for producing food such as rice, fruit and vegetables. However, in the process of processing land, community still uses manual methods so that it takes long time. This study aims to increase efficiency effectiveness farmers cultivating land can maximize their work. research resulted portable tractor be used cultivate loose soil which usually often chosen by grow va...

As robotic platforms are designed for human robot interaction applications, a full body sense of touch, or “sensitive skin,” becomes important. The Huggable is a new type of therapeutic robotic companion based upon relational touch interactions. The initial use of neural networks to classify the affective content of touch is described.

Globally, one in three adults has some level of measurable hearing loss, and 1.1 billion young persons are at risk for hearing loss attributable to noise exposure. Although noisy occupations such as construction, mining, and manufacturing are primary causes of hearing loss in adults, nonoccupational noise also can damage hearing. Loud noises can cause permanent hearing loss through metabolic ex...

This overview presents computational algorithms for generating 3D object grasps with autonomous multi-fingered robotic hands. Robotic grasping has been an active research subject for decades, and a great deal of effort has been spent on grasp synthesis algorithms. Existing papers focus on reviewing the mechanics of grasping and the finger–object contact interactions Bicchi and Kumar (2000) [12]...

Robotic systems have been increasingly adopted in several sectors of the society. To cope with this demand and diversity, researchers have investigated the Service-Oriented Architecture (SOA) to develop such systems. SOA promotes interoperability between software modules and heterogeneous hardware devices, and a better reusability and flexibility for robotic systems. However, due to the lack of...
