Development of self transforming robot with camera for surveillance
Project Area of Specialization Mechatronics EngineeringProject SummaryIn this project, a self-transforming robot is made while using the help of image processing it can also avoid the obstacles. The aim is to make a robot that can walk and move on wheels. While moving on wheels, the height and width of robot can be changed as desired according to the situation. This self-Transforming robot would be a kinematic machine, able to deliberately change its shape by re-arranging its part for the achievement of the specified task. It is provided with camera to detect obstacles in the path through the method of image processing and to reach a particular goal. It can possibly give three types of transformation.one would be spider-like for irregular surface. Second for passing from under the obstacle and third for the narrow gap.
Project ObjectivesOur project objective is to build a four legged robot that can change its shape according to its environment. By default it walks on four legs, in case when an obstacle is fronted by the robot, camera attached on it can detect the shape of obstacle through the help of image processing and changes its shape. Depend upon the obstacle or the environment infront of robot, It changes its shape and transforms into a car like structure. On wheels it moves beneath the obstacle. On a rough surface it spreads its legs and shows spider like movement by again shifting its shape. These three modes (walking, spider and car) are useful for overcoming an obstacle and changing its shape according to its environment.
Project Implementation MethodIn our hardware,
The materials used in a design limit the durability, strength, maintainability, energy efficiency and operating capability of the product. They also impact on the size and contribute to the total weight of the final design. A heavier material such a metal is typically stronger then lighter materials such as plastics but it requires more energy to move. The size of the design impacts on its ability to navigate around, through or over obstacles as well as its transportability.
Material we choose for our Robot is acrylic and Aluminum. Acrylic plate is used in the base and in the upper most portion of the robot. Motor and tire assembly is also mounted with acrylic. Acrylic has advantage over other materials as Acrylic is a tough transparent plastic, an alternative to glass. Its light weight, water proof and has appropriate strength.
Diffrent types of servo motors. their holders.
In our software,
we'll use solid works to make a CAD Model.
Proteus to do simualtions of software.
Microcontroller , diffren sensors.
MATLAB for image processing.
Benefits of the ProjectMilitary Purposes:
Day by day the world is moving towards modern warfare. As the weapons and means of warfare are getting more and more advance there lies a need to counter that. SelfTransforming robot can be used for the border surveillance, monitoring, tracking and combat purposes. It can be used to deliver weapons and other supplies to the soldiers right in the centre of firing line.
Search and Rescue:
As a result of natural calamities many lives are lost, due to poor access to affected areas such as in case of earth quick. Self-transforming robot can be used to access the inaccessible areas in time and provide the needed aid. It will also lower the toll of death of rescue workers who lose their lives while trying to save others.
Planet Exploration:
With the increase of pace towards outer space exploration and more different planet space missions, there is a great need of the robots that can move in different environments and go through multiple terrains to conduct explorations and do different experiments for the human research. Self-transforming robot can provide with the above mentioned tasks.
Technical Details of Final DeliverableServo Motors:
Servo motors are capable of turning to a specified position. They can control angular positions very precisely. A servo motor consists of a built in feedback circuit as well as a motor driver. It just needs one power line, one ground, and one control pin connected to any digital pin on the Arduino board.
Arduino controls the movement of the servo arm such that it can move to any angle between 0 to 180 degrees. The library servo.h allows the Arduino to control the gears and shafts integrated together.
Sharp IR Sensor:
The Sharp IR sensor is used for obstacle avoidance as well as motion sensing. It has a detection range of 4? to 32? (10 cm to 80 cm). Analog voltage gives the distance. Analog output can be connected to an analog-to-digital converter for taking distance measurements. The output can be connected to a comparator for threshold detection as well.
DC Motor:
Dc motors are used to move the robot when on its wheels. A total of four Dc motors are being used, one for each leg. The speed of the motor is controlled using the PWM pins of the Arduino board. To drive the motors two motor drivers L298 are being used.
Leg Assembly:
There are total four leg assemblies. Each leg assembly consists of five servo motors and a Dc motor. To connect the servos together we have used servo brackets. In each leg there are three multipurpose servo brackets, one long U-shaped bracket, two short U-shaped brackets and two L-shaped brackets. The brackets were connected together using nuts and bolts.
Hardware Fabrication:
The hardware was Fabricated according to the design and simulations. The base unit is made from aluminium angles with fitted acrylic sheets. The dimensions of the base unit are 10 x 10 x 3.5 inches. To support the base unit, pillars of brass were used. The base unit weighs 1.5 kg.
