    Design and Fabrication of an Artificial Leg Mechanism for above Knee Amputees
    (2018-06-26T05:55:09Z) Ganesh, Kumar C; Suhas, Bharadwaj K S; Rahul, M R; Rahul, P
    In recent years, there has been a worldwide interest in the improvement of mobility of people with amputations. In spite of significant development of new technologies during the last decade, there exists deficits in motor control because of reduced sensory perception in the amputated leg, asymmetry in leg kinematics in consequence of different leg mass and inertia, energy loss during power transmission from the stump to the prosthesis, prostheses are still energetically passive devices. This paper presents the use of Flex sensor which accomplishes the above tasks with a great degree of accuracy. Flex sensor is a device which measures the amount of deflection or bending. The surface signals picked up from the calf muscles of a healthy leg during the muscle activity are interfaced with a Microcontroller. These signals are processed, analyzed and used to actuate the knee joint of the prosthetic leg. Microcontroller is linked with the DC Servo motor to drive its knee joints, sets up non-linear dynamics and adopts control algorithm to improve the robustness, speed of response and accuracy. During the course of the present work, it is possible to control the rotation of motor of prosthetic knee joint using the sensor signals received from the healthy leg. Hardware and software design of the robotic limb is controlled using flex sensor and arduino controller. The completely designed prosthesis will allow users to walk with a better gait. Microcontroller programming can be done with an ease to suit the requirements.

    Personal Disaster Alert & Rescue Aid Using IoT
    (2016-07-12T09:14:54Z) Rahul, K; Jithin, P V; Rahul, P
    There have been so many disastrous incidents occurring throughout the year which makes us think why we are helpless even in this era with so much of advanced technologies. One such incident was the recent Chennai flood. Even though technology had helped in the rescue, it was not beneficial to the majority. This was the main motivation for us to choose “Personal Disaster Alert & Rescue Aid using IoT” as our area of project. The idea of this project is to provide a mechanism to make any alerts reach the common people faster and also help the responsible bodies get information about the affected people, so that the rescue operation can be more efficient and faster. This also helps to manage the medical needs effectively. This device is not limited to disaster but can also could be used for military operations as well as sharing any public information.
