Wi-Fi robot controlled Gesture Using the accelerometer
INTRODUCTION
AŽest Controlled robot is a robot that you can control using your gestures are not old buttons. You just need to wear a small device to manual transfer Exercises That year included meter acceleration. This will send the command the robot to a year so he can do whatever we want. The sending unit is on the comparator IC for analog-to-digital conversion and encoding for Any coder year use four a little time and then it will send out RF transmitter modules from year to year.
At the end of the receiving module RF receiver software is taking dekodiruetthe and encoded on it by using a decoder. This date is processed by a microcontroller and then, finally, the driver of the engine to control engines.
Accelerometer:-
AnAkselerometr is a kind of analogue, which gives the time of the year, moving in the X, Y, Z direction, or maybe X, Y directions only depends on the type of sensor. Here is a small image, the accelerometer sensor shown in the figure. We can see in the image that their some arrow indicating if we tilt sensors in this direction Then these dates in Pine-correspondent, that will change in analogue form.
The RF transmitter (TX):-
Transmitter module works at a frequency of 433 Mhz.
• The output is connected to the VCC Terminal + in chains.
• Date is connected to pin Passed or we can say that the encoded data.
• The following output shown in figure, which is connected to GND is ground terminal.
• Now is the last PIN is connected to a small ANT antenna wire I year.
Microcontroller AT89S52 programming process:
Processing is the most important part of a robot. Still porwe we get a date from a decoder based on that date, now we have to make a Decision here, some of the rolls of the microcontroller is evacuated. We use 8051 microcontroller circuit for the year of our decision to give them an opportunity. Our Microcontroller Atmel AT89S52 programming is informed by product name
The concept is to initialize the microcontroller is included below. We just reset the circuit and Need the generator, start the program.
Electric Drives (Motors):
The drive is actually the device that gives the movement or make the task as an engine. In the real world there are various types of engine available which works at different voltages. So we need them to run through the motor driver controller. To get between the engine and the interface of the microcontroller. We use Motors motor driver IC in our diagram.
