1. ADVANACED MULTILEVEL HIGH SECURED PINENTRY AUTHENTICATION SYSTEM It is based on the development of PIN security system .To make the user more comfortable , secure and many added advantage at a low cost with the high response circuit design. Users can directly access their Personalized Identification Number(PIN) by sending an OTP  message to the server blocking their card to take only limited amount of money by the second person and user can also block the card  incase the card is lost. Direct PIN entries are highly susceptible to shoulder  surfing attacks as attackers can effectively observe PIN entry with concealed cameras.

To achieve security and usability , a practical indirect PIN entry method stegano PIN it is designed to physically block shoulder-surfing attacks.A link between the appropriate mobile number and server is made to have limitation in money withdrawal. The LCD  displays  a characters,  where the user has to add the character with their original PIN number and the resultant  PIN has to be entered in the keypad. It remains limited to PIN-based authentication.



In most of the Industries robots play a major role in manufacturing process of a product and leads to Industrial Automation. Each robot performs the given task by programmers.In this project single Robotic ARM can be used in Machining, Painting, Assembly sector rather than using a single robot for one purpose. The Robotic ARM can also be controlled by Voice and Gesture.A Robotic ARM can do a single task which is programmed by the programmers.It is also Remote Controlled one,which controls the Robotic ARM through Hand Gesture using Flex Sensor.By using Different Axis in a Single ARM using Teach Mode and Repeat Mode several operations are performd.Voice Controlled mechanism can also be implemented. 


Vending machines have become an increasingly important distribution channel in public and private sectors. In Educational institutions and laboratories IC vending machine is of great importance. This System proposes a microcontroller based vending machine that dispatches integrated chips, once the RFID card is read. The users can select the required item after the card is scanned and collect the item in the output unit. The system is divided into three parts, the first part deals with the scanning of RFID card which provides cashless payment. The second one is the programming unit which is implemented using µC/OSII. The third part is the display unit which displays information and delivers the required item based on the information sent from the microcontroller. An embedded system based vending machine is designed to achieve a low cost, accurate, and portable machine that can deliver items automatically. 
4 ALPHA 1s



  • Sharing the joy. The upgraded version of the app’s control program features a sharing list for new actions, which can upload and download quickly. This allows you to share your joy with amateurs around the world.
  • Simple and easy to operate and control. With Bluetooth, it can be quickly connected to its mobile app. It is also compatible with iOS and Android.
  • Easily controlled via the APP. Using the APP terminal to control Alpha 1S is simple and easy. This allows you to display its advantages whenever and wherever possible.
  • Visual Programming at PC Terminal. It features editing software for 3D visual actions with an interface that is simple and easy to operate. This enables even non-professionals to edit in no time.
  • Highly precise. Alpha 1S has 16 servo joints, which can move with high precision, thus enabling it to perform various highly complex actions with ease and achieve human simulation.
  • Safe with strong protection. It's suitable for young amateurs and beginners for its “finger-friendly” structural design as well as eco-friendly and “shock resistant” materials.


The Ligo Mindstorms contain software and hardware to create customizable, programmable robots. They include an intelligent brick computer that controls the system, a set of modular sensors and motors. This robot is controlled by remote.It can move forward, backward, left and right side. At the heart of the product is the Intelligent EV3 Brick with powerful ARM9 processor, USB port for WiFi and Internet connectivity, Micro SD card reader, back lit buttons and 4 motor ports. It includes 3 interactive servo motors, remote control, improved and redesigned color sensor, redesigned touch sensor, infrared sensor.

The robot is Controlled via the infrared sensor system, Intuitive software (PC and Mac) with icon based drag and drop programming interface. Build and program robots on the go with the intuitive EV3 Programmer App available for iOS and Android tablet devices. 



quadcopter, also called a quadrotor helicopter or quadrotor, is a multirotor helicopter that is lifted and propelled by fourrotors. 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. In the early days of flight, quadcopters (then referred to as 'quadrotors') were seen as possible solutions to some of the persistent problems in vertical flight; torque-induced control issues (as well as efficiency issues originating from the tail rotor, which generates no useful lift) can be eliminated by counter-rotation and the relatively short blades are much easier to construct. A number of manned designs appeared in the 1920s and 1930s. These vehicles were among the first successful heavier-than-air vertical take off and landing (VTOL) vehicles. However, early prototypes suffered from poor performance, and latter prototypes required too much pilot work load, due to poor stability augmentation and limited control authority.
