Chassis for Robot - Line or Path follower Robot / Remote Controlled Robot

Chassis:

 A chassis consists of an internal framework that supports a man-made object in its construction and use. It is analogous to an animal's skeleton. An example of a chassis is the under part of a motor vehicle, consisting of the frame (on which the body is mounted) with the wheels and machinery.

AVR Micro controller based Line Follower Robot using Infrared Sensor, Driver IC L293D/Relays & AVR Dev Board

Introduction:

This article presents the design and implementation of line follower robot using AVR Microcontroller. It is a machine that follows a line, either a black line on white surface or vise-versa. The path is sensed by the IR (Infra Red) sensors. The microcontroller controls two DC motors of robot to navigate through its path.

Basic Principle:

The basic principle involved in this is it captures the line position with IR sensors mounted at front end of the robot.  The block diagram of the line follower robot shows that, when the sensor senses the path, output will be 0s or 1s which are then fed to the microcontroller, and then the microcontroller decides the next move according to the program. When both the sensors are indicating low (0) then robot start moving on the black path, for white if it indicates high (1) then it moves along the path.

How to make a line follower robot using logic gates

Introduction:

Here we are going to see about logical control robot, which means we have take some condition that it can satisfies 3 conditions:- In this we are going to take Move Forward, Backward and Stop. For that we are going to use any 2 logic gates which should satisfies 3 conditions and Driver IC for Motor.
In this project we can see about the following concepts-
•    Power Supply or 9/12v battery
•    DC Geared Motor or BO-Motor
•    Basic Motion of Robot
•    Logic used in the Running the robot
•    Logic Gates
•    Driver IC

8051 Micro Controller based Line follower Autonomous robot using IR sensor, Driver IC (L293D) & 8051 board

Introduction:

This article presents the design and implementation of line follower robot using 8051 Microcontroller. It is programmed to follow a dark line on the white background and detect turns (or) deviations and modify the motors appropriately. The path is sensed by the IR (Infra Red) sensors. The microcontroller controls two DC motors of robot to navigate through its path.

Basic Principle:

The basic principle involved in this is it captures the line position with IR sensors mounted at front end of the robot.  Below is the block diagram of the line follower robot, when the sensor sense the path, analog signal is given to the op-amp to produce 0s and 1s which are then fed to the microcontroller, then the microcontroller decides the next move according to the program. When both the sensors are indicating low (0) then robot start moving on the black path, for white if it indicates high (1) then it moves along the path. Microcontroller and driver circuit are used for the control of motors.
