Abstract

A majority of the human beings on this planet are deaf and dumb. The exchange of information between a deaf persons who knows sign language and the person doesn't poses a serious problem for them as compared to between who doesn't know the sign language. Since communication is the fundamental and one of the very important things to have in life therefore the person who doesn't know sign language feels alien in the atmosphere he lives in. Sign language is the non-verbal form of language which uses hand gestures to express feelings and to convey information and sign language is very popular among deaf community. This paper aim is to create a helping hand glove sensor for deaf people to communicate easily with other people. The glove has five flex sensors which are glued along lengths of five fingers on the glove. The glove produces a proportional change in resistance for every particular gesture. The analogue values which are the output of the sensors are converted into digital format. These gestures are analyzed using Arduino controller. This board compares the predefined voltage levels stored in the memory with the output of the flex sensor. And thus according to that a suitable match is found and a particular sentence is displayed on the LCD and also can be heard on the speaker. This is how the proposed sensor helps the deaf people to make their life easier than before and brings new colors to their life.

Abstract

Additive manufacturing more commonly known as 3D printing has been in the limelight of manufacturing research for a long. Many advances have been made in the past in elementary printing techniques, materials, and post-processing schemes. In this paper, a concept of a miniature pellet extruder is added at the end of the articulated robotic arm. The idea is to create a system that capable to print larger and more complex shapes of any parts with the help of a low payload capacity robotic arm and provide output as a single-piece structure. It also helps to print and handle objects with larger and more complex geometry with an optimized cycle time. Knowledge from this research work will also help to choose not only the right low payload capacity robotic arm, but also provides a logical approach for selecting a pellet extruder over a filament extruder.
