INTRODUCTION: The “Autonomous & RC Vehicle” is a
remote-controlled vehicle. In addition to the capability of being
controlled with a remote control,The “Autonomous & RC Vehicle” have
a smart autonomous mode that allows the unit to move freely without running into major obstacles.
DESCRIPTION:Two Modes Of Operation
Remote Control mode:
A remote control vehicle is defined as any mobile device that is controlled by a means that does not restrict its motion with an origin external to the device.
Controlling the vehicle with remote control.
CONTI…
Autonomous mode:
An autonomous vehicle is that vehicle that can drive itself from one place to another without help of driver.
Obstacle detection and avoiding the obstacle.
OBJECTIVES: Remote controlled vehicle is consist
of two major parts:
The Transmitter Unit.
The Receiver Unit.
CONTI… Commands from the keypad is
processed by a microcontroller unit, encoded and then transmitted by the RF transmitter at 300MHz.
On the receiving end, received commands are decoded, processed by the microcontroller and translated to a series of instructions.
CONTI…Another feature is of autonomous mode. Under the autonomous mode, sensors
are activated to detect obstacles .Then outputs are monitor by the
detection algorithm (code) that is running on the onboard microcontroller.
This algorithm acts accordingly and ensures the vehicle stays clear of obstacles.
METHODOLOGY:Hardware Design:
Motor Control
Signal Transmission
Detection Mechanism
Basic Hardware Design:
CONTI…Software Design:
Speed Control
Signal Handling
Detection Algorithm
Circuit Design Of Transmitter:
PHOTO-COUPLER:
The photo-coupler is used in between the microcontroller and the transmitter. The basic purpose of using this component to avoid the frequency mismatch and to prevent the microcontroller from the reverse current. It is consist of diode and the transistor.
BASIC STRUCTURE:
ENCODER-PT2262:
CMOS Technology.
Low power consumption.
Very high noise immunity.
Up to six data pins.
Wide range of operating voltage i.e. Vcc = 4 ~
15 volts.
Circuit Design Of Receiver:
INVERTER ULN2003: This inverter is used to prevent the reverse
voltage flow from the motor to the controller. It is consist of NOT gates and is very useful for driving a wide range of loads including DC motors, LED displays and high power buffers.
BASIC STRUCTURE:
MOTOR DRIVER L-298:
L-298 is a high voltage, high current dual full-
bridge driver designed to accept standard TTL logic levels and drive inductive loads such as relays, DC motors and stepping motors.
ULTRASONIC SENSORS:
AndLM 567
Why Using R40 & T40: ultrasonic sensors are used for the detection of
obstacles because ultrasonic sensors are more reliable than infrared sensor.
They could be easily available and less costly.
FEATURES:
Why Using LM567:
general purpose tone decoders.
Output wave fall time is 30ns.
Output wave rise time is 150ns.
Largest detection bandwidth is 10 to 13% of
central frequency.
