The project is to design and
construction of Robot controlling with Blue tooth to
Navigate in the desired place (with in
the range of Bluetooth), using the microcontroller.
The project was divided into two phases.
The First phase is to demonstrate the application of
Bluetooth communication for coordinated
robotic search. The second phase of the project
Attempts to control the robotic
movements which send the information to master Bluetooth.
The information flows in two ways: on
the one hand there are commands from the computer
To the Bluetooth robot for controlling
directions and also different characteristics of it.
This project deals with one of the
application of robotics. In this project one moving object is
Developed which is controlled by
Bluetooth technology. Micro controller along with the
Driver circuit is provided to run the dc
motor. According to the signal from Bluetooth
Device (connected to a system) robot follows
the path, which is driven by a stepper/dc motor.
