Abstract -The main objective of PRO-WHEEL is to perform multiple tasks at different surfaces. Briefly saying, it is a multi-track wheel. This project deals mainly with the application of stair climbing. Here, multi-track refers to the working of the wheel in different fields, like normal roads, farms, and several irregular surfaces. When there occurs any major problem due to some obstacles like mud, sandy roads, farms, etc., the arms inside the wheel opens via a motor connection which is further connected to the battery. These arms have rollers attached to their end that comes in contact with the surface and thus the area of cross section increases. Belt is attached around the wheel. This gets stretched due to its elastic property and its contact with the surface increases. In case of stair climbing, the open belt condition comes into play and the motion due to the working of motor enables it to climb the stair easily, as when compared to the normal closed belt condition.

Keyword: Multi-track, Multi-purpose, easy to operate I INTRODUCTION

During these previous decades, we have seen that the technology was not so well developed in order that we can be fully dependent on the automated machineries.

Overall looking at human comfort and demand, technology is changed accordingly. Vehicles are the most comfortable and easy operable tools to humans. But the vehicles are designed as per the particular road or for a special purpose. For that purpose, robots are being made. These are mostly manually operated and some automatically. But the robots are even designed to perform a particular task at a time; one job at a time. To get rid of these problems, a special machinery robotic vehicle is designed to carry out multiple functions

II FUNCTION:

The function of this vehicle designed is to perform job on various tracks, therefore stated as multi-track wheel. Also stair climbing becomes easy when the arms are opened and the belt is stretched. This enables the wheel to be broader, as the

belt surrounded also opens due to its elastic property and finally the surface are of contact between the road and the wheel increases. Due to increase in the surface are contact, the motion becomes easy and also less effort is to be

induced. At the end of the arms are attached the rollers, that can rotate 360°

on its own axis.

It is named multi-purpose wheel, as it can perform the normal job of rotating and moving the vehicle in normal track. But in case of uncertain conditions like sandy region, muddy areas, terrain roads; the wheel can perform well as compared to the normal condition with the help of arms, rollers and the belt taking these as prior components in action.

III PROPOSED METHODOLOGY /DESIGN

1. Base

Base is the main component of the vehicle. The material of the base is very high in tensile strength and rigidity. Each and every part of the vehicles is mounted over this base.

(2)

2 2. FIXED WHEEL

This is the fixed wheel attached to both the sides of the base. This wheel doesn’t rotate and is stationary. Motors and arms are attached to the fixed wheel.

3. ROLLER

Roller can rotates about its own axis and is pin joint

4. ACTIVE WHEEL

Active wheel, as the name suggests, is the active while working. It can rotate as the motor is allowed to give power to this wheel. Over this wheel is circumscribed the belt, which also rotates with this active wheel.

 Battery: 2v and 2.5amp

 Motor:30rpm and 60rpm VII ADVANTAGE OF PRO-WHEEL

Applications currently under development include:

 arm tractors and other agricultural equipment: The ProWheels allow a small tractor to do a larger tractor’s job with minimal field damage.

 Construction vehicles:

Unprecedented safe

maneuverability

 Military vehicles: New standards for versatility tenaciousness and safety

 Forestry: Previously unattainable combination of maneuverability and minimal ground damage

 Essentially creating a new and better tire, Pro-Wheel looks to become the tire of choice for

 ARMED FORCES

 AGRICULTURE

 DESERT AREAS

 COAL MINES

 WHEELCHAIR

VIII DISADVANTAGES OF PRO-WHEEL Maintenance & repair: The cost of maintaining and repairing the pro wheel can be substantially higher than a manual wheel.

Lnitial expense: Pro wheels are typically more expensive than standard manual wheels.

Size: Pro wheels are larger than manuals and may not be suitable in every home.

Weight: Pro wheels are much heavier than manual wheels. The size and weight makes them less portable than manual wheels and perhaps be too heavy for some lifts.

Limited power: If the battery packs are not recharged properly, you may end up with a dead battery before you return home.

Difficult for others to maneuver: If you become unable to move your Pro wheel on your own, pushing it is very difficult because of its weight and its build.

IX CONCLUSION

Wheel/track coupling type is a new type of mobile combination compared with the traditional wheel/track multiple robots which only contain one set of walking mechanisms. The structure of a wheel/track coupling type robot is simple and compact, and it can easily switch between wheel mode and track mode.

What is more important, it has a tail rod that can improve the stability of the movement through coordinating the gravity center. This combination is especially suitable for urbanization terrain in which area there are both flat grounds and occasional obstacle steps. Based on the geometry analysis, the theoretical scheme of the double four-bar linkage- type deformation mechanisms designed.

The dynamical model of stairs-climbing is either in wheel mode or in track mode using the classical mechanics analysis on the robot during the stairs-climbing process. The experimental results verify the correctness of the analysis methods of system models of the robot.

The design of the wheel was success fully done to meet the aim of the project. The entire assembly of the chair can be done by fabricating the remaining components and assembling them as per the design. One major short coming is the retraction and deployment of the mechanism. So far as the current design goes we have thought of rigidly attaching

(4)

4 the wheel with the inner plate of the mechanism by clamping and then driving the mechanism to climb up the stair case or descend down the staircase. But in practical scenario directly attaching the wheel with the inner plate is not a valid option because that voids the capacity of the wheel to move on plane level ground.

Hence one major area of work that has to be done to realize this project in the future is designing the deployment and retraction of the mechanism. One conceptual design so far regarding the deployment and retraction is as follows.

We can rigidly connect the entire mechanism to a lever arm that can be pivoted at a convenient point on the wheel frame. By rotating this lever arm we can bring the mechanism in contact of the staircase and hence deployed. But this idea can be possible if it can be detailed out. Finally it is necessary to have a full prototype testing and get consent from the members of the wheel using community REFERENCE
