Tracked Robot Fabrication tutorials

The following parts were fabricated for the constructions of the robot .They are explained one by one below.

WHEELS

The wheels used in the construction of robot were machine moulded plastic wheels with hollow space inside. The diameter of the wheel is 61 mm and the width of the wheel is 20 mm.

BELTS

The belts that we have used are reinforced rubber belts .Some of the remarkable characteristics are wearing resistant, high strength, waterproof, heat resistance, crack resistance, aging resistance and longer use life.  

The ball bearings that support the rear wheels need to be housed in a housing that could support the ball bearings and it also provides adjustable facility so that the slack that occurs in the belt over a period of time can be adjusted .It also facilitates the easy removal of the belt are loosening it.

REAR WHEEL SHAFT

The shaft shown  freely inside the ball bearing providing smooth motion .One end is threaded to connect the encoder wheel and the other end is connected to the wheel. 

BALL BEARING HOUSING 

The ball bearings that support the rear wheels need to be housed in a housing that could support the ball bearings and it also provides adjustable facility so that the slack that occurs in the belt over a period of time can be adjusted .It also facilitates the easy removal of the belt are loosening it.

PROVISION FOR SLACK adjustment

As the rubber belt slacks due to temperature variation and ageing a slot was milled in the robot’s body for slack adjustment which ensures that the belt stays taut at all times.

Internet Controlled Telerobot Using Flat File System

Hi Readers 

I've worked on a project "INTERNET CONTROLLED TELE- ROBOT USING FLAT FILE SYSTEM"

while in college and published my research work as a paper .I've deceided to give my paper to you people so that you could use it in your work and benefit from it .

My project is still online and you can login here and see the working .How ever the robot isnot connected to the computer .You can just get to know the layout and working code .

Heres the word document of my paper  .You can modify it as you like .

I am willing to give you the code on special request .

The Abstract and Introduction are given below .

Abstract - Our method aims at using the web browser for transferring the commands from the remote client operator to the robot’s control desk through a server which eliminates the need for costly equipments, complicated software’s and also consumes only a low bandwidth which is an added advantage .And moreover it provides security and eliminates the tedious process of IP address identification and verification used in the conventional methods of teleoperation through the internet. The main improvement that we would like to highlight is eliminating the need for installing client side software’s since the whole process can be done using the web browser ,through which the operator has real-time access to the robot .

INTRODUCTION

Today many robotic applications demand teleoperation. The current methods are mainly developed around wireless protocols which involve high cost equipments and can transmit only through a limited distance or by using complex software’s in the client end which consumes a large chunk of the bandwidth. The security concern of the process also becomes a huge question mark in these methods. 

So in order to eliminate the installation of software in the client end and to avoid the direct connection of the clients we need a server in between as some sort a meeting and a communicating point from where the operator and the robot can put and get the data .An php server was used for the purpose because of the ease of scripting and also its open source .And using this scripting a login interface was added as a first security measure.
