- 2. What is robotics?? Robotics is science of designing or building an application of robots. Simply robotics may be defined as “The Study of Robots”. Robotics develop man-made mechanical devices that can move by themselves whose motion must be planned, sensed, actuated and controlled and whose motion behaviour can be influenced by programming. The aim of robotics is to design an efficient robot

- 4. Omni Directional Robot It is a vehicle used to move in all directions. Our project aims at designing a omni directional robot equipped with three omni- wheels, mounted at 120 degrees apart. These wheels will be mounted on DC motors which will be driven by L298 motor drivers.

- 7. ATMEGA 128 The ATmega128 is a low- power CMOS 8-bit microcontroller based on the AVR enhanced RISC architecture. By executing powerful instructions in a single clock cycle, the ATmega128 achieves throughputs approaching 1 MIPS per MHz allowing the system designer to optimize power consumption versus processing speed.
- 8. DC MOTOR A DC motor is any of a class of electrical machines that converts direct current electrical power into mechanical power. The most common types rely on the forces produced by magnetic fields. Nearly all types of DC motors have some internal mechanism, either electromechanical or electronic, to periodically change the direction of current flow in part of the motor.
- 9. MOTOR DRIVER The L298 is an integrated monolithic circuit in a 15- lead Multi watt and PowerSO20 packages. It is a high voltage, high current dual full-bridge driver designed to accept standard TTL logic levels and drive inductive loads such as relays, solenoids, DC and stepping motors. Two enable inputs are provided to enable or disable the device independently of the input signals. The emitters of the lower transistors of each bridge are connected together and the corresponding external terminal can be used for the connection of an external sensing resistor.
- 10. OMNI WHEELS Omni wheels or poly wheels, similar to mecanum wheels, are wheels with small discs around the circumference which are perpendicular to the turning direction. The effect is that the wheel can be driven with full force, but will also slide laterally with great ease. These wheels roll forward like normal wheels, but slide sideways with almost no friction (no skidding during turns).
- 11. DTMF DECODER DTMF is the acronym for Dual tone modulation frequency. Robotic vehicle based on DTMF technology is explained in this project. When a key is pressed from our mobile, it generates a tone combination of two frequencies from our keypad. In the two frequencies, one is high frequency and another one is low frequency. This frequency can be decoded by the decoder IC into binary sequence. DTMF based robotic vehicle circuit consists of DTMF decoder IC, driver IC and motors.

- 14. CV AVR HP InfoTech presents a new version of the most popular (more than 14600 registered users) commercial C Compiler for the Atmel AVR microcontrollers. Code Vision AVR is the only Integrated Development Environment on the market that features an Automatic Program Generator (Code Wizard AVR) for the new XMEGA chips. Code Vision AVR V3, besides it’s own IDE, can now also be used as an Extension fully integrated in Atmel Studio 6.2. The Code Vision AVR Advanced version also features the LCD Vision Font & Image Editor/Converter and Graphic Display Libraries.
- 15. Isis Proteus The Proteus schematic capture module lies at the heart of the system, and is far more than just another schematics package. It combines a powerful design environment with the ability to define most aspects of the drawing appearance. Whether your requirement is the rapid entry of complex designs for simulation and PCB layout, or the creation of attractive schematics for publication, Proteus Capture is the tool for the job. Open Proteus in order to design their circuit, they found out that the components they have used in their project are not available in the Proteus Directory. In that case, there’s a need to design your own component in Proteus and place it in the circuit. Although, this new designed component won’t work as the real component but for presenting the circuit, it will be enough.
- 16. SINA PROG Sina Prog Program Download Guide will help to learn how to download hex file into all AVR microcontrollers. Connect the AVR USB programmer to the PC to Laptop directly or with the help of USB AM-FM Cable provided with the AVR USB programmer package. Then, connect the AVR Trainer Board-100 or any other microcontroller board that you have, with the AVR USB programmer through the 10 to 10 FRC Female Connector provided with the AVR USB programmer Package.
- 17. PROCEDURE The C program is written in the CODE VISION AVR software, where it has a facility for predefined header files. After the program is written, it is compiled and built. To simulate, we use the software ISIS PROTEUS. It checks for connection errors. To dump the tested program into the hardware, we use SINA PROG.
- 18. TYPES OF OMNI ROBOTS
- 19. ADVANTAGES The first main advantage omni directional robot is that it can move in all 8 directions i.e., in 360 degrees. Robots can work in factories and do the same thing over and over again and not do it any differently. Humans on the other hand will get tired after doing the same thing repetitively and could easily make a mistake. This robot to serve food or products, to carry material from one place to another, to send medicines to the patients kept in the isolated environments, etc.
- 20. DISADVANTAGE One main disadvantage that results from Humanoid Robots will be that many people are going to lose their jobs. It cannot be applied in automobiles because it can reduce mileage of the vehicles. The companies that put money in research and development of these robots and do not sell any will also be losers.
- 21. CONCLUSION Omnidirectional vehicles have great advantages over conventional (non-holonomic) platforms. They can crab sideways, turn on the spot, and follow complex trajectories. Robots are taking over tasks which are dull and dangerous. Technology Should be used and implemented for Construction but not for destruction.
