Obstacle Avoiding Robot using ATmega16 Microcontroller

Durga Prasad

In today’s world ROBOTICS is a fast growing and interesting field. ROBOT has sufficient intelligence to cover the maximum area of provided space. It has an infrared sensor which is used to sense the obstacles coming in between the path of ROBOT. It will move in a particular direction and avoid the obstacle which is coming in its path. Autonomous Intelligent Robots are robots that can perform desired tasks in unstructured environments. The minimum number of motor allows the walking robot to minimize the power consumption while construct a program that can produce coordination of multi-degree of freedom for the movement of the robot. It is found that two motors are sufficient to produce the basic walking robot and one voltage regulators are needed to control the load where it is capable of supplying enough current to drive two motors for each wheel.

Android Phone Controlled Robot using Arduino

Deepesh Verma

The Android phone that stays in your hand most of the time is useful in many other applications apart from Whatsapp, Facebook; appliances; monitor your health parameters. How it would be if it can control a Robot, which can assist in your daily work. With this project you can make a robot that can be controlled by an Android Phone, over Bluetooth Communication.The robot is built around Arduino interfaced with a Bluetooth receiver to receive commands from Android Phone.The basic Block diagram of the system is as:

The operation being very simple, as the app on the phone transmits data serially over a Bluetooth connection established between it and the receiver.The commands are received and are processed according to the program fed into Arduino, upon which the further controlling is done. Motors are given instructions, in the way user commands them through his phone.

Wireless Monitoring and Controlling Rescue Robot using Zigbee

Durga Prasad Kolhari

The robot is operated through PC using wireless technology using zigbee and using wireless camera we can view both audio and video on the TV. This robot has a high power LED which acts as a light source when light intensity inside the pipe is low .It is a low cost robot used to monitor the changes of different parameters in the industrial pipes. By connecting temperature sensor to the robot we can get the temperature of dangerous zones in PC itself. By connecting smoke sensor to the robot we can get the information related concentration of smoke or gases in respective fields

Step by Step: Line Follower Robot Without Microcontroller

Rachana Malviya, Technido

Line follower is an autonomous robot which follows either black line in white are or white line in black area. Robot must be able to detect particular line and keep following it. For special situations such as cross over’s where robot can have more than one path which can be followed, predefined path must be followed by the robot.Line following is a task in which robot has to follow the line. It must be capable of taking various degrees of turns to follow the curved lines also.The Line following Robot moves to follow a line drawn on the floor. This Robot follows the black line which is drawn over the white surface .

Cell Phone Controlled Pick and Place Robot

Durga Prasad Kolluri

Although, the appearance and capabilities of robot vary vastly, all robots share the feature of a mechanical, movables structure under some form of control. The control of robot involves three distant phases: perception, processing, action. Generally, the preceptors are sensors mounted on the robot, processing is done by the on board microcontroller and the task is performed using motors or with some other actuators.

In the project the pick and place robot is controlled by a mobile phone that makes a call to the mobile phone attached to the robot. In the course of a call, if any button is pressed a tone corresponding to the button pressed is heard at the other end called ‘Dual Tone Multiple frequency’ (DTMF) tone. The robot receives these tones with help of phone stacked in the robot. The received tone is processed by the microcontroller with the help of DTMF decoder IC MT8870. These IC sends a signals to the motor driver IC l293d which drives the motor in directions forward,  reverse, left, right, pick, release, up, down, rotate left, rotate right.

Obstacle Avoiding Robot Without Microcontroller

Rachana Malviya, Technido

Obstacle avoidance is one of the most important aspects of mobile robotics. Without it robot movement would be very restrictive and fragile.Obstacle Avoiding is a task which is used for detecting the objects placed in the path of your robot or any vehicle. So, to protect robot from any physical damages.

An obstacle avoiding robot is an intelligent device, which can automatically sense and overcome obstacles on its path. It is developed without micro-controller in order to eliminate critical circuits, difficult programming etc. All you want to do is to just understand the circuit diagram and start doing this robot. This simple technique can be incorporated in wheeled robots to keep them away from damages and accidentsObstacle Avoidance is a robotic discipline with the objective of moving vehicles on the basis of the sensorial information.

Cell Phone Controlled Robot Without Microcontroller: Step by Step Guide

Siddharth Dev

Cell phone operated Robot is a Robot whose movement can be controlled by pressing the number of cell phone. The robot can move forward, backward, right or left which depends on the numbers you are pressing. The property of Robot to operate by the cell phone helps you to operate the robot from some distance

The Cell Phone controlled Robot uses DTMF (Dual tone-multi frequency) module. It is capable of receiving a set of command (instructions) in the form of DTMF (Dual tone multiple frequency) tones and performs the necessary actions. The robot is controlled by making call to the mobile connected to the robot. The robot performs various operations like moving forward, backward etc. if any key is pressed in the course of the call, by hearing at the other end of the call (i.e. at the mobile connected to the robot ). Each key corresponds to a particular frequency which is decoded by the DTMF decoder & processed by logic circuit by giving each key a particular operation like moving forward, backward, right, left etc. 

Mobile Controlled Robot

Ganeev Singh

 Mobile controlling is done mainly with DTMF decoder. DTMF stands for Dual Tone Multi Frequency. This module can take up-to 4 bits of data at a time (i.e. 0-15 decimal values).

DTMF needs two mobile platforms, one for sending instructions while another for receiving them. This module contains a IC which decodes the signals received and convert it into 4 bit data.

Resistor Image

Resistor is a passive component used to control current in a circuit. Its resistance is given by the ratio of voltage applied across its terminals to the current passing through it. Thus a particular value of resistor, for fixed voltage, limits the current through it. They are omnipresent in electronic circuits.

Capacitor image



Capacitor is a passive component used to store charge. The charge (q) stored in a capacitor is the product of its capacitance (C) value and the voltage (V) applied to it. Capacitors offer infinite reactance to zero frequency so they are used for blocking DC components or bypassing the AC signals. The capacitor undergoes through a recursive cycl...

L293D Motor Driver IC Image

L293D is a dual H-bridge motor driver integrated circuit (IC). Motor drivers act as current amplifiers since they take a low-current control signal and provide a higher-current signal. This higher current signal is used to drive the motors.

Accelerometer Based Hand Gesture Controlled Robot

Amol Wabale

In many application of controlling robotic gadget itbecomes quite hard and complicated when there comes the part of controlling it with remote or many different switches.

Mostly in military application, industrial robotics, construction vehicles in civil side, medical application for surgery. In this field it is quite complicated to control the robot or particular machine with remote or switches, sometime the operator may get confused in the switches and button itself, so a new concept is introduced to control the machine with the movement of hand which will simultaneously control the movement of robot.
