Flashlight Controlled Solar Powered Robot using Arduino
This project is a Light gradient sensitive Robot with Solar charging capabilities, in other words it seeks out the light to charge itself. It accomplishes this behavior with a set of Four Light sensitive Photo Resistors in voltage divider circuits. The Arduino unit reads the four values which correspond to the intensity of the light received by the sensors through its analog read pins. It then applies a high voltage across a reed switch which completes a circuit between a 9v battery, and two Toy Motors, resulting in turning or moving towards the light.These motors were not able to be activated directly with the Arduino, if you get small enough motors, the switching portion of this project may be omitted without loss of functionality. If any of the four Photodiodes is registering much higher than the others, it detects which Photodiode is receiving the heightened signal and turns or moves in that direction for as long as the heightened signal is being received.

Basic Mechanics of Robots
The meaning of this word deals with the motion of the ROBOT. In basic mechanics we will try to understand motors, gear mechanism and physical structure of a robot. Depending upon area of uses ROBOT size may differ from each other. It should have the proper equipment to complete or perform a task. Like we have hands, fingers and arm to hold a thing similarly our ROBOTs require. Our hand, fingers and arm move at a certain angle and in a certain direction which is known as degree of freedom. For movement, our body contains several joints likewise we provide joints in robots too. At joints we fix different types of motor for movement. These motors can be servo, DC geared and stepper.

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
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
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.

It is always better to make bots in a set of modules which can be assembled together to form the required bot. For the dust bot there are two things required, first a gripper that can hold the balls and second a vehicle that can take that gripper from one place to another. First of all it is required to make a vehicle that can be controlled by the wired controls. After accomplishing this task we need a mechanism to grab the balls. Further the grip of the grabber should be of such strength that the balls don’t fall of the bot till we reach the finishing end. The movement of the gripper should be bidirectional and quite precise as we require the movement of the gripper in both the directions. The stability is the success of every bot. More the stability in your design better is your bot. Hence, the arm holding the gripper should be properly fixed and shouldn’t be unstable. Therefore, aluminum rods were chosen with clamps for enhanced stability of the gripper. And most important the bot should utilize the off the shelf material and it must be really economic.
Cell phone operated Robotic Arm
This is also picked and place type robotic application. But this has a unique feature that it is controlled from cell phone. It’s all the movements are controlled from any cell phone. That means you can control this robot from anywhere in the world where GSM / CDMA network service is available. Isn’t it very interesting??!!!!????…..The robot has built in GSM / CDMA cell phone that receives signals from other cell phone. One has to call the number of the cell phone (that is inside robot) from his cell phone to activate it. Then by pressing different keys from 0 – 9 form the phone he can control the movements of the robot. It is 4-axis robotic arm. It’s all four motions are controlled by 2 DC gear motors and 2 servo motors.Let us start with mechanical structure of robot.
