  1. Mobile controlling robot

  2. What is a Robot ? • “A re-programmable, multifunctional manipulator designed to movematerial, parts, tools, or specialized devices through various programmedmotions for the performance of a variety of tasks.”

  3. A robot must have the following essential characteristics: • Mobility: It possesses some form of mobility. • Programmability: implying computational or symbol- manipulative capabilities that a designer can combine as desired (a robot is a computer). It can be programmed to accomplish a large variety of tasks. After being programmed, it operates automatically. • Sensors: on or around the device that are able to sense the environment and give useful feedback to the device • Mechanical capability: enabling it to act on its environment rather than merely function as a data processing or computational device (a robot is a machine); and • Flexibility: it can operate using a range of programs and manipulates and transport materials in a variety of ways.

  4. CONCEPT In this project we use smart logic and control system of embedded system by micro controller. In this project we use DTMF and micro controller as main processors.

  6. DTMF Decoder • Dual-tone multi frequency (DTMF) is used for telecommunication signaling over analog telephone lines in the voice-frequency band between telephone handsets and other communications devices • The version of DTMF that is used in push-button telephones for tone dialing is known as Touch-Tone.

  7. Cntd……. • This is the internal pin diagram of the DTMF decoder

  8. Cntd….

  9. MICRO CONTROLLER • In our mobile control robot we are using 40 pin micro controller

  10. Cntd……. Micro controller consists of………. • 8 kb of flash memory 256 bytes of RAM • 32 Input and Output lines. • Three 16bit timer or counters. • A six vector two level interrupt architecture

  11. VEHICLE CONTROL • We use two small gear DC motors to drive the small robot. • One motor for the left wheel and another one for right wheel. • Left motor drives for right turn and right for the left turn

  12. MOTORS • To make the mobile robot we need to have motors and the control circuitry that could control the motors. • There are different kinds motors available for different applications • DC motors • Stepper motors • Servo motors

  13. ADVANTAGES • Wireless control. • Vehicle navigation with use of 3G technology. • Takes in the use of the mobile technology which is almost available every where. • Surveillance system.

  14. DISADVANTAGES • Cell phone bill. • Mobile batteries drain out early so charging problem. • Cost of project if cell phone cost included. • Not flexible with all cell phones as only a particular, cell phone whose experience is attached can only be used.

  15. FUTURE SCOPE • Car driving. We can add camera & other accessories to robot which can perform any desired task.

  16. Cntd….. • Fire accident applications. With the help of mobile phone we switch on/off the fountain also, with the help of fountain we spray the water vapour on the fire.
