The aim of this Rocker Bogie Suspension System project is to develop a surveillance robot for defense which is capable of moving in all surfaces and is capable of driving in rock terrains and live video streamlining with help of a camera.
This robot has a special mechanical structure which is capable in driving rock terrains which is only possible with chain robot, but chain robot has some bugs and to overcome those bugs we designed a mechanical structure as following in figure
Coming to the mechanical structure of this robot it contains 8 wheels which are derived with DC motor and these motors are fixed to aluminum plates which are 220mm length, 30mm width, and 3mm thickness this has 12mm drill in the center for fixing C shape wing.
The shaft in the center is for balancing the mechanical structure for either side of robot There is push rod mechanism on either side of the robot which is helpful in limiting suspension height when driving terrain rocks which is also adjustable manually as per the requirements.
In this project we used some aluminum material as well as metal steel depending on the mechanical structure where it needs more strength and weight in particular area used metal steel material and remaining place aluminum is being used.
This is the Rocker-Bogie Suspension System with the dual bogies and this has the rocker in between to protect the vehicle from over collapsing
Existing model was in 6 Wheels
Proposed System is with 8 Wheels which can protect itself from over falling
This can be controlled via the android app with the help of Bluetooth Network.
This can be navigating multiple terrains in uneven surfaces can travel in mud areas
We have developed the entire robot in MS Sheet.
The below Project is solar based Rocker-Bogie Suspension System with Gripper attachment.
The previous one is for surveillance Purpose and this one for pick and place operations
Introduction to Develop a Multiple Interface Based Fire Fighting Robotics Project:
A monitoring system that is based on the real time is presented in a multiple interface that is usually used in the automation of home. The home and building security system includes security modular, appliance controller module, fire fighting robot, television security device, GSM modem, remote supervise computer and appliance control module.
Industry personal computer is the main controller of the fire fighting robot. In order to control the mobile robot we order the command that acquire sensor data and programmed the supervised remote system with the visual basic. Security information can be received by the robot from the interface of the wireless RS232 and a generate user interface is designed for the computer control of the fire fighting robot.
In the results of the experiments the users will control the mobile robot with the help of the RF controller, remotely supervise computer and supervised control. Obstacle can be avoided by the robot using IR sensors as well as ultrasonic sensors as per the fusion method of the multi-sense. Two flame sensors can be used to know the source of the fire and fight it with the help of the extinguisher. We are also planning to design an obstacle detector in the future modular using the IR sensor and ultrasonic sensor along with the fusion of the algorithm.
For getting more quick and easy environment map in the outdoor and indoor we need to combine the laser finder . Usually a home provides safety of the security of factory, office building and laboratory is necessary to the life of human and we have also created a multi-sensor security based system that includes a robot for fire fighting in the intelligent building we design a fire fighting robot that comes with an extinguishers. 50cm, 80kg and 130 cm are the respective shapes.
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.
The aim of this project is design a robot with super intelligence system and can also obstacles in its way and also fire. It is developed to detect fires and bombs for security purpose.
The robot has best flexibility and it controlled with wires fitted with motors to control motion a micro controller is embedded to control all robot operations.
The robot contains a fire sensor whenever the fire is detected the sensor detects and it alarms.
It has a sensor for detecting bombs whenever the landmine or bomb was detecting it tells by alarming. The whole robot works on 12v DC battery.
Tools Used for creating Robot:
- Embedded c Language
- Small Device Cross Compiler &Kiel uvision3
- 8051 Microcontroller
- It is Low cost and easy to operate
- It consumes Low power
- It is fully automated
Fire alarm structure:
For the detection of fire reverse biased germanium diode was used here. The resistance of diode is 10 Kilo ohms. The reverse resistance of germanium diode drops at 70 degree the resistance dropped to 1 kilo ohm and the alarm is activated through 555 ic pin 4 becomes positive through the resistor R1.
Binary Code for Motor movement:
Kiel software for robot:
The features are it contains a +5V output current with well regulation of 100ma.
The circuit protection has capability of protecting the IC when it’s gets overheated.
The circuit complexity is to build. Power supply is Unregulated DC 8-18V power supply.

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.
