A line follower robot from design to implementation: Technical issues and problems
ABSTRACT The Line follower robot is a mobile machine that can detect and follow the line drawn on the floor. Generally, the path is predefined and can be either visible like a black line on a white surface with a high contrasted color or it can be invisible like a magnetic field. Therefore, this kind of Robot should sense the line with its Infrared Ray (IR) sensors that installed under the robot. After that, the data is transmitted to the processor by specific transition buses. Hence, the processor is going to decide the proper commands and then it sends them to the driver and thus the path will be followed by the line follower robot. TABAR is a line follower robot designed and tested in order to attend at Tabrize line follower robots competition. But it encounter with some technical and mechanical problems. In this Paper, we have illustrated the process of design, implementation and testing TABAR, a small line follower robot designed for the line follower robots competition. The technical and mechanical issues and problems also have investigated.

- "Almost all the line follower robots, whose are previously implemented have a limitation that they can only follow either black line on a white surface and vice versa  and . A color line follower robot is depicted in  which is partially autonomous. "
ABSTRACT: This paper introduces the multiple source Multiple Destination Robot (MDR-l) having the ability to choose a desired line among multiple lines autonomously. Every line has different colors as their identities. The robot can differentiate among various colors and choose a desired one to find its target. Unlike any other simple line follower robot, this robot can be considered as a true autonomous line follower robot having the ability to detect presence of obstacle on its path. A powerful close loop control system is used in the robot. The robot senses a line and endeavors itself accordingly towards the desired target by correcting the wrong moves using a simple feedback mechanism but yet very effective closed loop system. The robot is capable of following very congested curves as it receives the continuous data from the sensors.IEEE Business Engineering and Industrial Applications Colloquium; 01/2013

ABSTRACT: This paper outlines the analysis and development of a sunbathe laundry robot. The study explores the application of light dependent resistor (LDR) with PIC16F887. Two parameters that were studied include the response and sensitivity of LDR and water detection circuit to halogen lamp and amount of water on the detection circuit. The experimental setup for light detection measured via LDR and linked to a dc motor. A basic PWM configuration setting was developed and downloaded to PIC16F887 microcontroller to control the speed of the robot movement. The minimum speed was used to maintain robot stability. Voltage divider rule is applied on LDR to select the best resistor for ADC output. An L298 motor driver was interfaced to microcontroller board and motor to control the direction and speed of dc motor using PWM. The analysis shows that the best angle for LDR position is 45° while the voltage for the water detection circuit within the range of 0.58 V to 0.60 V.

ABSTRACT: Today, the autonomous robots are widely used to perform task in a wide variety of application. A number of research works has been carried out to examine and remove problems faced by the current robotic world. The theme of this paper is to discuss different design consideration along with their limitations and solutions for an autonomous robot which will be able to climb and cross the ramp and place boxes on to stands placed at different points of arena using line following principle. The implementation of this robot was the theme of “NERC 2010”. The robot has also the limitation of weight, size and power.Procedia Engineering 09/2012; 41. DOI:10.1016/j.proeng.2012.07.265
