Basic Idea
my graduation project is two wheel balancing mobile robot. . It is a small robot balanced with two parallel wheel only . The main idea of this project is how to make the robot balance. First we decide to use the gyroscope to make it balanced . gyroscope is angular sensor give us the tilt angle and the direction . it is a new technology used in air plane navigator, helicopter , tanks and segway. But we were failed to bought the gyroscope because it was expensive . so we are search for another component that can used in detect the tilt angle. Finally we decide to use two infrared sensors to detect the tilt angle of the robot to make it balanced
Design
We are used Catia system to design and draw our project . Catia is the best and first Cad/Cam system in the world . We used only cad system in our project . We are used part design, assembly, fitting, drafting and kinematics.
Electronic component
PIC16F876 Microcontroller
This power full ( 200 nanosecond instruction execution) , easy to program, have three port , analog to digital convert and acapture/compare/pwm.
L298 Dual Full-Bridge Driver
The L298 is used in balancing robot to drive the two DC motors. it is a high voltage , high current dual full bridge driver. two enable inputs are provide toenable or disaple the device independently of the input signals
Sharp GP2D120 Infrared Range Finder
The GP2D120 is a compact, self-contained ir ranging system incorporating an IR transmitter, receiver, optics, filter, detection, and amplification circuity the range of the sensor is between 5 to 30 cm
LCD is the most inexpensive and simplest user interface you can provide when interfacing with such processors as the Basic Stamp, PIC, etc, in displaying user prompts, messafes and displaying data
Design & Make Electronic Board
Control
We are use Pic Basic Plus language to programming our robot . it is simple programming language and it is easy to use . it is similar to visual basic language that give use flexibility to use it . you can used assembly or C language to programming your robot . we were used pic basic to make PID control to our robot
