Online Project With An Brief Description

1)COMPUTER CONTROLLED WIRELESS ROBOT

In this project, we will learn How to design a PC controlled wireless robot with AVR ATmega16 microcontroller using 433MHz RF circuit. Here, we will use the PC keyboard as the input device and the 433MHz RF circuit to drive the robot wirelessly in different direction and we will display the direction of movement of robot in the PC.

PC will send the signal (ASCII value of pressed key value) to the ATmega16 microcontroller through its serial port. But current generation PCs and Laptops do not have serial port in them, so we will use one USB to Serial converter cable which will create a virtual serial port in the PC /Laptop.

Again, the output of USB to Serial cable can not be connected to microcontroller directly as the output voltage of USB to Serial Cable corresponds to RS-232 level. But the ATmega16 microcontroller needs TTL/CMOS voltage levels.
For this, we will use MAX-232 voltage converter which will convert RS-232 voltage level to TTL one and vice-versa. The ATmega16 microcontroller will read the serial output of MAX-232 through its USART and it will process it to know which key of the PC keyboard is pressed.
After knowing which key of the PC keyboard is pressed, the ATmega16 microcontroller will send the required 4 bit signal to the HT12E encoder of RF transmitter circuit.

The HT12E will encode the 8 bit address and 4 bit data given to it and then it will transmit the encoded signal serially to the RF module.

The RF module will transmit the encoded data and address wirelessly and it will send the direction of movement of robot to PC also (direction of robot will be displayed in PC).
At the receiver end, the RF receiver module will receive the encoded 4 bit data and 8 bit address. Then, it will transmit the encoded signal serially to the HT12D decoder which will decode the received signal to 8 bit address and 4 bit data. After decoding, the HT12D will compare the received 8 bit address with its local 8 bit address.
If the received address and the local address are same, then the received 4 bit data is sent to its output pins else the received data is discarded. The 4 bit output of HT12D is sent to the DC motor driver (L293D) of the robot to drive the robot in the desired direction.
  The control keys for the robot are F or f, B or b, L or l, R or r and S or s to drive the robot in forward, backward, left, right direction and to stop it respectively. Now, press different keys from the PC and drive your robot wirelessly as you want.

2)HAND GESTURE CONTROLLED BOAT

In this wireless gesture controlled robot project we are going to control a robot using hand gestures. This is an easy, user-friendly way to interact with robotic systems and robots. An accelerometer is used to detect the tilting position of your hand, and a microcontroller gets different analogue values and generates command signals to control the robot. This concept can be implemented in a robotic arm used for welding or handling hazardous materials, such as in nuclear plants.

3)ULTRASONIC VIBRATION BASED BLIND STICK

The vibration of motor is activated when any obstacle is detected. The blind stick is integrated with ultrasonic sensor . This proposed system uses the microcontroller ATmega 328 embedded system. Abstract: Today’s world is moving very fast and in this fast world we should walk together and no one should left behind. But there are some parts of society which are lagging behind because of some disabilities. One of them is blindness. Blind people have to rely on others for travelling and other activities. So to solve this problem to some extent we are introducing Ultrasonic Walking Stick for Blind People. This paper discuss about how this stick is built and how it will help blind people. There are various methods to do it and we are using helpful concepts from each paper

4)THERMO-ELECTRIC COOLING HELMET

ABSTRACT Human life is so precious and valuable, that it should not be compromised under any cost. The concern over the safety of vehicle drivers has pushed for invention of new equipment that can save lives. According to Statistics from the Insurance Institute for Highway Safety (2010), it is mentioned that nearly 70% of mortality in road accidents occur due to head injury, where the rider has not worn a helmet. It is not that people are very negligent about their lives on road, but that they experience dozens of discomforts by wearing helmets. The most common discomfort is that, heavy sweat occurs due to excessive heat formation. This paper deals with the development of cooling system for biker’s helmet using thermoelectric technology. The system consists mainly of a heat sink, aluminum passageway and Peltier module. The prototype is fabricated and mounted onto biker’s

7)SUBAUTONOMOUS OBSTACLE AVOIDING SYSTEM

subautonomous obstacle avoiding system(here subautonomous
system means it can pretend like autonomous vehicle on your choice ,there is an selection option in which its depend on your choice ,in manual mode you have to control the vehicle by an wireless controller(transmitter) and if you select autonomous mode then it can run and sense infront obstacle and change its direction of motion.
