Obstacle Avoidance Voice Controlled Robotic Vehicle Project

This Obstacle Avoidance Voice Controlled Robotic Vehicle Project work is mainly based on Arduino, Motor driver, and Bluetooth module. Arduino is an open-source prototyping platform that is based on easy-to-use hardware and software. Arduino makes use of an ATmega328 microcontroller.

Robotics has become a major part of our day-to-day life and also it plays a vital role in the development of new technology in the engineering field. This is a simple type of remote control car, where the ordinary microcontroller has been replaced by Arduino and the IR sensors have been replaced by the Bluetooth module.

The remote device to control this device can be any android or IOS mobile phone. And in this, we have also included the ultrasonic sensor which detects any obstacle present in front if any it stops the car. This project can be made used on a large scale for real-time vehicles.

hardware implementation of the circuit diagram including ultrasonic sensor

This project is controlling cars not by using sensors or transmitters but by using Bluetooth which is a very simple medium of communication in the present day. The remote device which controls this project is an android device that has an inbuilt Bluetooth module. Through Bluetooth, we can connect two devices.

Here we have inserted a Bluetooth module that gets connected to the phone‘s Bluetooth, which allows us to communicate and allows to take control over it. The main control of the car is played by the Arduino UNO which is the micro-controller ATMEGA32. Arduino has played a major role in the robotic section and it had made it easier to convert digital and analog signals to physical movements.

This project is Bluetooth-based because it gives us a wider range of control and more efficiency. It also gives us the advantage of changing the remote anytime, so that we can use any android device including phones, tablets, and computers. Physical barriers like walls and doors do not affect controlling the car. We have also included the ultrasonic sensor which helps the bot to stop automatically when an obstacle is present before it. An obstacle detector is added to protect the system from obstacles on the way by using an ultrasonic sensor that is mounted on the servo motor.

The voice-controlling commands are successfully transmitted via Bluetooth technology and on reception; the desired operations successfully take place. This project reduces human efforts in places or situations where human interventions are difficult. Such systems can be brought into use in places such as industries, military, and defense, research purposes, etc.

Hardware components to implement this project:

  • Arduino UNO
  • Motor shield
  • Ultrasonic Sensor
  • Bluetooth Module (HC-05)
  • Servo Motor
  • Jumper Wires
  • Bo Motor 300 rpm
  • Car Kit

Robotic Lanmover Final year Project Based on Robotics with Report

Introduction to Robotic Lanmover Final year Project:

The implementation and design of a robotic lawnmower, yardbot is represented in this paper and the main objective is to craft a lawn mover that can mow the grasses in a specific area automatically within less than 20 minutes. It should also able to avoid collisions with the obstacles that may locate in that area. Usually the obstacles that are present in a lawn and therefore must take into consideration are flower pot, fenced area, table and so on. In case the lawnmower comes in contact with any moving objects then it will engage the mover for 30 seconds and then move off from the field area.

The main motto is to achieve a create a frame and to implement perfect algorithms for the the creation of such a motor. It is also followed by the designing of an efficient, navigational and functional algorithm that can process data from a completely different GPS, ultrasonic sensors, digital IMU , laser range finder and a touch screen. The use of coders and output of algorithms will control the direction and speed of the movement.

It is a tedious job to mow a field using a lawn mower and usually a person tends to avoid it. There are two ways in which you can avoid doing this job firstly by engaging someone else to do the job for you in return of some money and secondly to use a robot to accomplish the task.

Here we are focusing on a complex robotic lawn-mower as the existing simple mower has not been accomplished to create a successful mover that can perform exactly even in complex design fields.  The robotic lawn mower proposed in this project is based on the GPS navigation system and is a sophisticated device that is capable of mowing complex and large size fields.

ECE Project Report on Autonomous Robots

Introduction to Autonomous Robots ECE Project:

Autonomous is the word which clearly tells that it works on its own without any guidance. Autonomous Robots are those which work independently without any particular tasks or any kind of human guidance. Most of the robots works with some extent of autonomy and these are of various kinds some robots can be of autonomy to some extent and some completely.

The strength and the extent of autonomy is based on the work or task that the robot has to be done for example if a robot has to clean a floor or lawn it some one kind of autonomy and the robots which work in space has one kind of autonomy all these are based on the place in which they work. For any kind of robot the exact work and the kind of work and the place in which it has to work must be determined before as this can be unpredictable.

The most important thing in the research of robotics is they have to enable based on the environment it has work as working on the land and in space has many variations. A complete independent robot has a capability of gathering information regarding the environment and also has the capability of working without human intervention for longer period and also can move its parts or some parts without human guidance.

The autonomous robots are designed in a way that they can avoid situations which are harmful to itself or others. The autonomous robots gains novel abilities such as adjusting the strategies based on the surrounding situation and also for completing its tasks. This paper deals with the autonomous foraging which is an apprehension among the social anthropology, human behavioral ecology and also the robotics artificial life and intelligence.

ADDED FEATURES IN OUR BOT

 Our GPS Navigation Robot Project has its unique code of 16 characters. It is encrypted in the permanenthidden storage memory unit of microprocessor, where it acts as a “black box” of our bot. The entire history is stored in it. It is a separate process which saves only the event history (control signal and direction Total Power Consumption till last update) of 64MB RAM at very high processing speed of 12KB/sec.

 In our Robot the location of memory unit is sent to main processor (ARM 9).when the code is accessed the complete event history is shown to administrator. It enable by performing the separate internet protocol (IP) based server to note the event history.

 The system gets its updation once in two minutes at 12KB/sec .At that time the motor is in OFF state, where the memory management is essential, so it holds nearly 10 to100KB data.

 We are trying to manipulate in most appropriate forms. It is used locate even at remote area.

CONCLUSION:

       Our GPS Navigation Robot Mechanical Project design is cumulative approach of both the electronic and mechanical ideas. It is designed with various references and guidance taken from our faculty, books, sites and journals. We put up our innovative ideas by analyzing serious present day issue, and trying to work out with it.

Mechanical Approach of the GPS Navigation Robot Project

Mechanical Approach:

Kinematics:

The GPS Navigation Robot Project we have designed to traverse on all terrains is on the concept of getting support from all the sides and having the ability to move ahead. The dimensions of the robot are 1600*965*810 mm.                                                     .

Design of Wheels and Motors:

The locomotion of bot is designed with six wheels so that the stability of the vehicle is high and moreover while climbing the steps or moving in rough terrain it will be able to have more support. Wheels of diameter400mm and thickness200mm are used. The wheels with V-THREAD profiles are selected to meet the desired need to move in all terrain. D.C Motors with specification of 40kg torque and 150rpm are designed to meet the desired speed and the load ratings. Similarly in total there are six motors one for each wheel hence each wheel will be having independent drive. The motors are placed in the wheel hubs supported by c-clamps.

Mechanism of Linkage:

          Kinematic of bot has three linkages in total. Each linkage supports two wheels. The front two wheels of each side are connected by one linkage and the rear wheels are connected by another linkage. Each linkage is designed on the concept of Double Rocker Mechanism. According to which there are two cranks connected to the main link. Similarly in this model the two C-clamps which are connected with the main link and the wheel acts like crank. Due to the presence of this type of linkages there is no separate suspension mechanism needed. At all point of times and at all positions always all six wheels will be touching the ground. This is the most advantageous point of having linkages.

 Double Rocker Mechanism

          In the above diagram A and B are the two cranks and c is the main linkage which is shown in the Double Rocker mechanism.  

FIG: shows the linkage in connection with the wheel

Steering Principle:

Apart from six D.C Motors, four servo motors are placed in between the C-clamps and linkage except the two middle wheels. So the wheels can be turned in any direction. The wheels if properly turned to the required angle, the entire vehicle may completely turn in its position up to 360°.The directional gyro which is of electronic model when fixed in the correct axis can find out how much exactly the wheel’s angle is displaced. Hence when the wheel has been turned to the required angle the action from the micro controller can be given to cutoff the voltage to the servo motor there by removing its action.  As each wheel has independent drive hence while turning the differential drive is obtained by giving variable supply to motor.

Material Selection of Chassis and Other Surfaces:

The chassis is the platform for electronic and mechanical tools. The chassis which should be light in weight as well as having high load capacity should be selected. Hence it was designed to use CNC Titanium or EPO resin.

 The two surfaces which are extruded from the chassis are shown transparent in the diagram drawn in the   pro-e modeling. This is due to the fact that both the surfaces are made of a transparent glass fiber made of carbon composite so whatever changes or deformations taking place could also be easily identified and rectified easily. Antenna is placed in the rear end, while the camera setup is placed in the front end. The camera setup has both stereo and C-MOS camera.

Control Architecture of the GPS Navigation Robot Project

Our GPS Navigation Robot holds a micro processor and three micro controllers for multi task assignment.

The camera action, memory allocation, motor action and GPS way point verification are the synchronous process, where the continuous clock pulse is required.

Here by we use the Control Architecture,

ARM 9 with VME bus based micro processor.

ARM 7, ATMEL 89C51, Motorola 69HC11 are the three micro controllers used for speed and motion control drivers, GPS sensors and E-stop and Image Processing analysis respectively.

All the data has been send through IEEE 1394 fire wire bus controlled at fixed sequence.

GPS Navigation Robot Final Year Mechanical Project

Positioning Sensors Used To Navigate On Rough Terrain:

Global Positioning Sensor:

Constructional Working of GPS:

GPS sensor for Navigation Robot is used to navigate the bot reach the fixed destination. Here we use differential gps system, where the carrier frequency is very high even at low signal status certain adaptive methodologies to reach our destination. The functional block shows how the operation is performed by our bot. 

Functional Block Diagram of the GPS Navigation Robot:

 Functional Block Diagram of the GPS Navigation Robot

The block diagram of Final Year Mechanical Project clearly shows the functional working of gps that is here the set point (current position) is compared the first waypoint. Once the destination is reached the program memory enqueue the second way point and so on. If the designated waypoint is not reached again it checks till the destination is reached. 

Performing the Navigation Using GPS and Camera:

The effective way of using adaptive robotic technology is performing the complex operation simultaneously to do the desired operation. Similarly we have performed the simultaneous operation by performing both obstacle avoidance and positioning using stereo camera and gps sensor respectively. The main advantage of performing this GPS Navigation Robot operation is maximum nearness error can be avoided that is created during real time positioning. The block diagram clearly shows how the navigation is performed.

 Performing the Navigation Using GPS and Camera

e-Stopping:

we perform the e-stop operation by providing stop signal to the driver .this we attain by converting the availabe frequency (crystal frequency) to PWM signal by using PWM converter .this signal is fed to the motor driver to stop the bot it is be. The block diagam shows the operaton of e-stopping.
