Wireless control of Robotic Arm using RF-FSK Techniques

The aim of the project is to control the robotic arm using rf-fsk technique. The main design principles used in designing the industrial uses which are flexible and easily enhanced for future use.

In some industries there is a big problem where the human person cannot work. Which means the temperature of the room will be more than maximum temperature.
In order to overcome the problem which is mentioned above it can be solved by this project. The robot can work where human person cannot work and also we can control the arm of the robot using wireless technique which is popular now days. The wireless technique used in our project is rf-fsk.

Hand Gestures recognition technology based wireless surveillence bomb diffusion-system

This is an interesting robot that can be controlled by hand gestures and by a RF remote. This can be moved forward and reverse direction using geared motors of 60RPM. Also this robot can take sharp turnings towards left and right directions. This project uses AT89S52 MCU as its controller. A high sensitive induction type metal detector is designed using colpitts oscillator principle and fixed to this robot. Also a mobile phone signal isolator is interfaced to the kit. When the robot is moving on a surface, the system produces a beep sound when bomb is detected. Simultaneously a signal is fed to the jammer section to switch on the jammer. This jammer diffuses the bomb by jamming the mobile signal of GSM or CDMA or 3G networks.
The RF modules used here are STT-433 MHz Transmitter, STR-433 MHz Receiver, HT640 RF Encoder and HT648 RF Decoder. The three switches are interfaced to the RF transmitter through RF Encoder. The encoder continuously reads the status of the switches, passes the data to the RF transmitter and the transmitter transmits the data.
This project uses 9V battery. This project is much useful for mines detection and surveillance applications.

Hand gesture based wheel the chair

The use of powered wheelchairs with high navigational intelligence is one of the great steps towards the integration of severely physically disabled and mentally handicapped people. Driving a wheelchair in domestic environments is a difficult task even for a normal person and becomes even more difficult for people with arms or hands impairments. Tetra pelagic people are completely unable to operate a joystick unless they use the tongue, which is obviously a very tedious task. Simultaneously blind and paraplegic people deal with a very uneasy situation which couples two problems: locomotion and localization. The Rob Chair system is being developed to overcome the problems described above, allowing the end-user to just perform safe movements and accomplish some daily life important tasks.
3 Axis Acceleration Sensor Board based on ADXL3XX from Analog devices is used for gesture recognition. It is a first generation 3 axis acceleration sensor. User could get acceleration value of X, Y, and Z axis. And it is widely used in shock, slope, and moving detection. Output sensitivity could be select by simply set voltage level on few pins. The output of the sensor is analog mode.
A prototype chair is implemented with a small chair and 60rpm motors are used to move the chair. A free-wheel is arranged to change the chair direction according to user’s requirement.This project uses 12V rechargeable battery. This project is very much useful for the disabled.

GSM based car engine control Implementation to stop the car theft

An embedded system is a combination of software and hardware to perform a dedicated task.Some of the main devices used in embedded products are Microprocessors and Microcontrollers. Microprocessors are commonly referred to as general purpose processors as they simply accept the inputs, process it and give the output. In contrast, a microcontroller not only accepts the data as inputs but also manipulates it, interfaces the data with various devices, controls the data and thus finally gives the result.

PAPERLESS E-CASH MANAGEMENT SYSTEM BY USING AN I-BUTTON TECHNOLOGY Project

The i-Button is a computer chip enclosed in a 16mm thick stainless steel can. Because of this unique and durable container, up-to-date information can travel with a person or object anywhere they go. The steel i-Button can be mounted virtually anywhere because it is rugged enough to withstand harsh environments, indoors or outdoors. It is small and portable enough to attach to a key fob, ring, watch, or other personal items, and be used daily for applications such as access control to buildings and computers, asset management, and various data logging tasks.
