  3. 3. Robotics is the branch of technology that deals with the design, construction, operation, and application of robots, as well as computer systems for their control, sensory feedback and information processing. These technologies deal with automated machines that can take the place of humans in dangerous environments or manufacturing processes, or resemble humans in appearance, behaviour, and/or cognition.
  4. 4. HISTORY Elektro(1939)Westinghouse Electric Electro is the nickname of a robot built by the Westinghouse Electric corporation between 1937-1939. it could be walk by voice command, speak about 700words, smoke cigarettes and move his head and arms. Elektro’s body consisted of a steel gear, cam and motor skeleton covered by an aluminum skin.
  5. 5. ELECTRIC DRIVES  The electric drive systems are capable of moving robots with high power or speed. • This types of robotics operation can be done by either DC servo motors or DC stepping motors. • The electric drive system will be perfect for small robots and precise applications. Most importantly, it has got
  6. 6. DC SERVO MOTOR A servomotor is a rotary device that allows for precise control of angular position, velocity and acceleration.  It consists of a motor coupled to a sensor for position feedback.
  7. 7. INTERNAL VIEW OF DC SERVO MOTOR
  8. 8. DC STEPPER MOTOR A stepper motor is a brushless DC electric motor that divides a full rotation into a number of equal steps.  The motor's position can then be commanded to move and hold at one of these steps without any feedback sensor.  It is an open-loop controller.

  11. 11. POWER REQUIREMENT  In general these type of electric drives require 12V or 24V for its operation  We can convert the 220V,50Hz ac into dc by the help of rectifier  The speed of these drive can be control by PWM control  IC 7805 use for conversion of voltage range 9-38v to 5v for electronic equipment.
  12. 12. MICRO CONTROLLER ATMEGA 32 An integrated circuit, or IC, is small chip that can function as an amplifier, oscillator, timer, mi croprocessor or even computer memory.  It is build from semiconductor materials, normally Silicon.  In present scenario an IC contain 1billions of transistor.
