Remote Control Based Robot (Service Provider)


One of the most recognizable forms of intelligent systems is robotics, though the

issues in intelligent robots are common to other types of intelligent systems. Use of

robots is growing both on Earth and in space, in large part due to increased capacity for

machine intelligence. In industry, as in space exploration, acceptance of robotics requires

very high reliability. Robot is defined as a mechanical design that is capable of

performing human tasks or behaving in a human-like manner. From the industry and

space we propose to bring the advancements of science in everyday life and arrange

robots for commercial domestic uses.

Robots are comprised of several systems working together as a whole. Our

Remote Control Based Robot will act as a service provider that will serve the guests at

home and in parties and can also double up as a moving office records and files keeper.

The type of job the robot does dictate what system elements it needs. Robots can operate

by remote control or autonomously. It is capable of demonstrating an array of

applications. Our Robot can move around on wheels. This Remote Control Based service

provider can be moved/ controlled using remote control that is mainly transmitter based

and will employ a Joystick or a plain remote. Remote control sends information as decided

by the human operator.

This project will facilitate the understanding of the following topics:

Coding in Assembly for 8051 series Micro controller for time constraint

acquisition and transfer of data.

Relay mechanism through ULN2003.

Dc Motor control mechanism.

Stepper Motor control mechanism.

Receiver work function.

Remote control mechanism through micro controller.

The AT89C51 micro controller is the robot's brain and controls the robot's

movements. It's usually acts like a device, which is used to store information about the

robot and the work environment and to store and execute programs, which operate the

robot. The control system contains programs, relay control mechanism and various other

processing activities, which enable the robot to perform.

A remote control robot sends instructions from a human operator

through remote. Stepper motors behave differently than standard DC motors. Instead of

rotating continuously when power is applied, stepper motors move in small increments or

steps. Additionally, a stepper motor is constructed with several coil windings that must

be energized in the proper sequence to achieve shaft rotation. Reversal of the energizing

sequence will rotate the shaft in the opposite direction. Stepper motors are commonly

used in accurate motion control. They allow controlling any motion with high precision

by counting the number of steps applied to the motor. Our project describes how to drive

stepper motors with 89C51microcontroller. We are also using drivers (ULN2003). Relays

have been connected to one of the drivers. The ULN003 offers solutions to a great many

interface needs, including relays and motors.
