Servo Motor

Interfacing Servo Motor with Atmega32 Microcontroller

Servo Motor Servo Motor is a DC Motor equipped with error sensing negative feedback to control the exact angular position of the shaft. Unlike DC Motors it will not rotate continuously. It is used to make angular rotations such as 0-90°, 0-180° etc. Stepper Motors can also be used for making precise angular rotations. But Servo Motors are preferred in angular motion applications like robotic arm, since controlling of servo motors are simple, needs no extra drivers like stepper motor [...]

Cell Phone Controlled Land Rover Using Logic Gates

What’s Science for a small child ?At that age, no one of us is aware about the vast branches in science ,yet we are very curious to know.There will be lots of  Why’s and How’s in our mind which makes the elders irritated.By seeing a toy car,we always get wondered. Without knowing any robotics or electronics inside we just want to make our own toy car with clay and blocks.So its not wrong to say that every child has scientist [...]

Servo Motor

Introduction Servo Motors are ordinary geared down DC Motors equipped with servo mechanism for precise control of angular position. A servomechanism or servo refers to an error sensing negative feedback which is used to correct the performance of a device. Servos are used for precise positioning in robotic arms, legs, RC Aeroplanes, Helicopters etc. Servo Motors do not rotate continuously, their rotation is limited between fixed angles. Usually these motors have rotation limit from 90° to 180° and some special have limit 360° or more. An [...]

Stepper Motor or Step Motor

Introduction to Stepper Motor It is a brushless, synchronous DC electric motor, which divides the full rotation into a number of equal steps. It is also known as Step Motor. For example, in the case of a 200 step motor, one complete rotation (360°) is divided in to 200 steps, which means one step is equal to 1.8°. It can take only one step at a time and each steps are equal. The exact position of a stepper motor can be [...]

Motorola Xoom 2 and Xoom 2 Media Center Review

Motorola Xoom 2 made a new footprint in the field of tables. It arrives at a point where Apple’s iPad still dominates in the tablet market. Motorola has introduced two new branded slates Xoom 2 and Xoom 2 media center edtion. The Xoom was the first tablet to arrive with Android Honeycomb, an OS dedicated to the tablet form.  The Xoom 2 looks similar to its predecessor, with some subtle changes. The corners of the slate are slightly cut-off, much like some recent Motorola [...]
