Dexto: Eka: is a tele-operated anthropomorphic robot which is approximately 5ft 1" tall. It is also India's first tele-operated humanoid and the tallest. . The project was begun with the goal of achieving tele-presence while maintaining low developmental costs. "Dexto" is derived from the word dexterous and "Eka" is the Sanskrit word for one. The project was started with the intention of creating a fully autonomous/tele-operated robot that can be deployed real time in the span of a few years. The project comprises a series of robots each one improving upon its predecessor. The intent behind the project was to save lives. These robots can be controlled from anywhere in the world. In accident-prone industrial areas, these low-cost tele-operated robots can be deployed and in case of unpredictable disasters, any harm would befall the robot rather than precious human life.
About DEXTO: EKA:
Dexto: Eka: is a tele-operated anthropomorphic robot with three modes of operation: dependent, semi-sovereign and sovereign. In the dependent mode, the tele-operator has complete control over the robot. In the semi-sovereign mode, the tele-operator has partial control but the robot is able to make decisions of its own should a situation prove detrimental to its well-being. In the sovereign mode, the robot has complete autonomy over its actions.
Dexto: Eka: has robotic arms of 6 Degrees of freedom each and an omnidirectional mecanum wheel drive. The mecanum wheel drive is quite unique as it provides motion with no directional restraint and can easily navigate congested spaces. We get a 10 Degrees of freedom from our locomotion drive. Such a system combining 12 DOF arms and a mecanum wheel drive is unique to Dexto: Eka:. The communication between the robot and the tele-operator takes place via a Wi-Fi channel. Latest Wi-Fi module called RN-XV module is being used to achieve wireless communication. The user is able to see the environment the robot is in via a live feed provided by an IP Camera mounted on the robot.
The tele-operator governs the robot through a human-machine interface which includes a Graphical User Interface (GUI), an exo-frame and a control column. The exo-frame enables control of robotic arm in slave mode, whereas the control column aids in manoeuvring the movement of robot. The robot is able to mimic the motions of the tele-operator with great accuracy. Every joint of the robotic arms can be controlled using the wearable exo-frame. The GUI besides monitoring the robot can also act as an alternative to the exo-frame and control column. The robot can be completely controlled from anywhere in the world using the software that has been developed for it.
Complete automation of the robot is achieved by focussing on four main parameters: Distance, Direction, Orientation and Obstacle Detection. For calculation of these parameters we used Quadrature encoders or Hall Effect sensor for Distance, Compass module for direction, Accelerometer for orientation and Ultrasonic sensors for obstacle detection. The robot is viewed as a point, hence its position in the plane is given by its coordinates, and the result of the snapshot (hence, of the observation) is just a set of coordinates in its local coordinate system: this set forms the view of the world of robot.
The students of NCU university made the university proud again as they surprised the global leaders in electrical domain and the top most colleges in India by marking their presence and securing the 2nd runners up position in student’s innovation pavilion held in GRIDTECH 2015 (5th International Exhibition & Conference) at ITPO, Pragati Maidan, New Delhi from 8th to 10th APRIL, 2015. They were also rewarded with appreciation and a cash prize of Rs. 25,000

India is considered to be the fastest developing country in the world but still lacks in ensuring basic rights to individual especially women which are still trapped in the clutches of various evils like molestation, eve teasing and the worst among all is RAPE. Even the protection of women outside or sometimes in their own house is doubtful as there is no proper safety device, so atrocities against women can now be brought to an end with the help of a device called suraksha.
Suraksha is a security system specially designed for girls. It makes use of latest technology and electronics to give better solutions. This device will prove to be very useful and user friendly.
Suraksha is a unique device which can be used in various ways and has a wide scope. Due to its sleek design and high sensitivity it is very user friendly and effective, it can be embedded into various devices such as mobile phones, various automobiles (public as well as private transport), jewellery, work places etc. Thus it is designed in such a way that it finds its presence everywhere. It can also be installed at shop or a mall.
It can play a major role in the upcoming projects such as CCTNS (crime and criminal tracking network and system) in which all the police records all over India are digitised and all the police station throughout the country will be integrated. We will also create a database for the police station to identify the victim.

GPS based Anti-Collision Device
In addition to Rear end and Head On collisions common in any train operation system, there have been instances that train (say on UP line )after derailment infringes the adjacent line and there is a collision with the train coming on other line (Down line). Another type of collision is at Rail-road level crossings, where trains collide with road vehicle because of negligence on the part of road traffic. Many measures have been taken on Indian Railways to avoid all types of such collisions and except on Mumbai sub-urban area where AWS (Auxiliary Warning System) is functional, all others requires human interventions. Because of possibility of human errors, such accidents can take place.
In order to prevent such collisions, Anti Collision Device (ACD) has been invented. ACDs have knowledge embedded intelligence. They take inputs from GPS satellite system for positions of the trains in a sections, updates and network among themselves for exchanging this train information in continuous handshaking mode, with the help of radio modems inside the trains. In case if there is a situation of collision, as predefined, ACD takes decisions for timely auto-application of brakes to prevent dangerous collisions.

A quadcopter, is a multirotor helicopter that is lifted and propelled by four rotors. Quadcopters are classified as rotorcraft, as opposed to fixed-wing aircraft, because their lift is generated by a set of rotors (vertically oriented propellers).
Quadcopters generally use two pairs of identical fixed pitched propellers; two clockwise (CW) and two counter-clockwise (CCW). These use independent variation of the speed of each rotor to achieve control. By changing the speed of each rotor it is possible to specifically generate a desired total thrust; to locate for the centre of thrust both laterally and longitudinally; and to create a desired total torque, or turning force.
Quadcopters differ from conventional helicopters which use rotors which are able to vary the pitch of their blades dynamically as they move around the rotor hub.

The rehabilitation for the handicapped is a big social issue in the world. There were many studies about assistive devices for the handicapped. The loss of all or part of the arm is a catastrophic event for a patient and a significant challenge to rehabilitation professionals and prosthetic engineers. The large, upper extremity amputee population in India has, historically, been poorly served, with most having no access to support or being provided with ineffective prosthesis.
A survey report by National Sample Survey Organization shows that every year 23,500 amputees are added to the amputee population in India, of which 20,200 are males and 3,300 are females. These data indicate that the incidence rate is higher in rural areas, and there are five to six times as many male amputees as female amputees every year. The volume, social NGO services offer very limited support and commercial services have lacked expertise and reliable technology. In recent years, the arrival of organizations like Otto Bock has made high quality service standards and devices accessible to more amputees. Over the last decade, there has been an emergence of improved services and accessibility to international products. The complete or partial loss of an arm represents both a significant psychological and physical loss to the patient. Adjusting to and compensating for this loss also poses a physical rehabilitation challenge that must be addressed by the coordinated involvement of various medical and para-medical disciplines. Upper limb prosthesis should ideally compensate for the loss of fine, coordinated movements of the hand, provide tactile sensation, proprioceptive feedback,
The design is divided into three parts:
The general design approach has been to begin with the definition of desired objective behaviors, rather than the use of available components with their predefined technical specifications. With the technical specifications of the components necessary to achieve the desired behaviors defined, the components are either acquired, or in most cases, developed and built.
