Omni wheels Robot for Effective Surveillance and Transportation Purpose

Abstract

Industrial and technical applications for remote robots are growing in importance. They are already being used for monitoring, testing and transportation activities. One of the main requirements for an independent remote robot is its ability to navigate the workplace, avoid obstacles and find its way to the next location, in order to perform its function, skills known as local performance and navigation. Navigating robots under different world conditions such as very steep slopes, ramps, slippery slopes and slippery terrain is a major challenge. In project work, the Omni-wheel with a 60-Degree of inclination is designed and tested in an intrusive, sloping and deceptive environment. Annex acclerometer and gyrometer sensors are common. Keeping track of the platform up to a minimum no matter where the robot is located is our goal. Omni wheels are specially selected to make navigation easier in any conditions. In order to balance ground collisions and active sedation in a moving environment, we use a simple method where the surface of the robot will remain in contact with the ground and the robot will align with the slope. The project introduces Omni steering wheels in Mecanum and discusses the kinematic relationships of the four-wheel drive Mecanum. Forward and Inverse kinematic was taken from this project.

Introduction

I. INTRODUCTION

In this project, we focus on the design and development of a four-wheeled Mecanum mobile robot from a fixed viewing space. The whole process is similar to the design of other intelligent systems or microsystems. First of all, modularized wheels with a straightforward suspension system are designed to detect the dynamic and unstable motion of a moving robot. A multi-layered body structure is used to accommodate easy development and various applications. Second, the control system needs to pay attention to the reliability, safety, and intelligence of the mobile robot. Therefore, the low-level controller uses an industrial level controller to control movement, and the high-level controller uses an embedded industrial PC to process multiple sensory data. To automatically navigate to an unfamiliar home environment with a small structure, data from the tire coders and the Kinect view sensor are integrated to create a local portable robot. Finally, a mobile robot is used in IMS to transfer objects through test testing. It is expected that the mobile robot will provide a smart navigation solution for smart factories with low cost and high associated accuracy.

In order to move the materials flexibly and smoothly through the solid vegetation area, an omni-directional robot based on the four wheels of Mecanum was designed. The portable robotic system is made up of three separate layers to facilitate its integration and redesign. Each modularized wheel was fitted with a straight suspension mechanism, which ensures moving durability and keeps the distances of four wheels constant. The control system consists of two-level controls that are used to control the movement and processing of multiple sensory data, respectively. To make the mobile robot roam the unknown indoor space with a small structure, Kinect view sensor data and four-wheel-mounted sensors were combined to create a portable locomotive robot using an expanded Kalman filter for processing. Eventually, a mobile robot was incorporated into an intelligent production system. Experimental results show that the omni-directional mobile robot can move steadily and independently in the indoor and industrial areas.

II. PROBLEM STATEMENT

This project discusses the problem of controlling the default height and step length of the Omniwheel robot system. Navigating robots under different world conditions is a major challenge. In a planned project of transporting goods, softly and smoothly on a solid surface, the Omni-directional mobile robot is built and tested on a ramp, in a convenient and secluded location. In order to measure ground collision and effective movement on a slippery surface, we use a simple method where the surface of the robot will remain in contact with the ground and the robot will align with the slope.

IV. LITERATURE REVIEW

1. H. Ghariblu [1] proposed a circular robot with a steering wheel mounted inside an empty circular case. The driving unit contains three sets of omni-wheels for robot movement. The mathematical model was also developed using the construction of Newton – Euler.
2. W Chen [2] proposed an omnidirectional round robot that was designed and operated using a propeller ball mounted inside a round shell and driven by two orthogonally mounted rollers.
3. V A. Joshi [3] used an old nonholonomic system. This is done using the help of two internal rotors and an angular pressure conservation system.
4. Halme [4] has proposed a paper on flexibility and control of a mobile robot designed to function as a small sensor and actuators in an area where stability is of paramount importance.
5. Bicchi [5] introduced a special type of moving robot called spherical whoes motion based on two ancient nonholonomic systems namely the unicycle and the plate-ball system.
6. C Camicia [6] published a paper based on the kinematic model of sphericle. It combines two types of nonholonomic barriers and its flexible model.
7. Amir H ??A [7] describes an example of a circular robot that can move in any direction. The design incorporated an internal movement system that distributes weights by highlighting close-knit pegs inside the sphere and enabling the robot to move at a constant speed.
8. Qiang Zhan [8] proposed a universal circular robot made of glittering ball-shaped shell and an internal drive unit. In two motors fitted with an internal drive unit, one engine is used to steer the robot and the other to steer.
9. UM. Kabala [9] introduced a robot called the “RoBall,” with an internal gimbal machine. The robot has two wheels that make up the IDU. By changing the shape of the heavy weight hanging on the IDU the contact areas of the two wheels to the outer shell vary and thus provide mobility.

The circular robots mentioned above have many advantages and disadvantages. A few of them are expensive, difficult to use and difficult to control. The proposed robot discussed in this paper is expensive and easy to control. It  ??nsists  ?f  three  sets  ?f  ?mni  wheels  ??nne?ted  t?  individu?l  m?t?rs.  .Thanks to the unique IDU architecture the robot is stable and easy to control.

XI.  RESULT & DISCUSSION

A. Design Problems

During the construction of the project, the team faced many challenges. These problems are::

1. Omni-Directional Motion: The robot can travel to many places; right, left, front, back etc. So the wheels were important to produce all of this movement, then the robot needed something special the shape of the wheels because the wheels around the world cannot help making this movement. Mecanum the wheels are one of those wheels that can produce this movement..
2. Wheel Design: The first problem that is addressed when designing a tire is choosing the number of rollers, because the load that the tire can carry depends on the number of rollers. Then the number of rollers that can achieve the desired goal of the robot is nine rollers. The second problem is the roller angle that allows you to connect the two flanges together, the angle that meets what you want is 22?.
3. Carrying Mechanism: The robot carried a load of up to 150 kg. So it was necessary to have an engine with good torque with a high voltage of 24V, motors with these structures are wheel chair motors.

XIII. URE WORK

To improve the viewing angle the ultrasonic sensors will be placed in corners, over the wheels, instead of placed between the wheels. Converting h bridges into one that requires one PWM signal per vehicle.

In the near future work, Omni wheeled robots can be designed using a hydraulic piston that gives the robot extra power to perform mechanical work in the field. Robot wheels can be further developed to navigate winding and sloping terrain. Continuously the Omni-wheel robot platform can be designed to be sturdy to carry additional loads in the area. These types of robots are used in the military, industry and various other applications.

Conclusion

The development of the Omnidirectional vehicle was further enhanced by the efficient operation of this type of structure and the addition of a ground-moving vehicle platform that could move in an unusual way. Omni-directional vehicles are divided into two categories that describe the type of tire design they use: standard wheel designs and special wheel designs. Omnidirectional mobile robot with Mecanum wheels for educational purposes. The robot has full omnidirectional motion, thanks to its special Mecanum wheels. More information on common and special wheel designs, Mecanum tire design features and robots, kinematic models, and electrical and control techniques have been introduced. Because of its mobility skills and its versatility, the robot mentioned in this chapter can be used as an exciting learning platform.
