Project Summary

A Robot is a machine that is intended to perform a specific program dependent on writing computer program; it can play out different functions all at once. A wireless camera is utilized to transmit live video from the war field. These Pictures/videos can be seen live on a monitoring screen at the base station and appropriately we can respond to the circumstance. The camera works on a DC power supply. The recipient is put in the far off station. Nowadays robot plays a vital role in our day to day life, thus reducing human activities. The main function of Spy robot is to roam around high sensitive region and provide video information from the required environment to the remote monitoring station. In this project, one can control the robot using Wifi reducing human effort. The user can continuously monitor the surrounding activities of robot location with live video streaming using wireless camera from the robot. This robot is modeled with Raspberry Pi microcontroller which control the robot behavior. The proposed spy robot is used in sensitive areas. During our summer break, our main focus was on the body design of our robot. For that, we searched for many possible designs of the already proposed models and made modifications in the previously designed modules. After the selection of design, we searched for the components to be used in our model which will be later explained in the components section. Robot is designed using Raspberry Pi as the controller and coded in Open CV-Python programming language to implement various control functionalities of the robot. The DC motors are controlled by General Purpose Input Output (GPIO) control signals of Raspberry Pi with motor driver module to drive DC motors using H-bridge. Signals from all sensor modules, relay and driver module are given to Raspberry Pi over GPIO pins. All hardware is powered by the supply board provided with the 12 V power battery.

Project Objectives

The main objective behind developing this robot is for the surveillance of human activities in the war field or border regions in order to reduce infiltrations from the enemy side. The robot consists of  wireless camera which can transmit videos of the war field in order to prevent any damage and loss to human life. Military people have a huge risk on their lives while entering an unknown territory. The robot will serve as an appropriate machine for the defense sector to reduce the loss of human life and will also prevent illegal activities. It will help all the military people and armed forces to know the condition of the territory before entering it.As the world is progressing, everything which was manually done is replaced by remote controlled systems and robots. The concept of this robot is to detect a person in any remote area where it is not easy, feasible and safe for humans to operate. The robot will be controlled wirelessly and help us identify the target person.It will also be able to cross certain obstacles, thereby depicting a real environment scenario. This has many applications in disaster managements and tactical situations.

Project Implementation Method

Our approach to design a real-time spying robot  with a remote camera on it, for live video streaming of the sensitive area on our monitoring device consisted of many subdomains. Our robot will be performing two major operations which are:

• Spying for the required target

• Obstacle crossing To carry out these two operations, we will be using different methods and techniques. These are:         1. Facial recognition and identification of the targeted object:

      The major goal is to build a spying robot for use in defense field where operations such as, identifying a criminal take place .Continuous monitoring by humans is a dangerous job, and the same activity can be done by a robot. The spy robot can watch and it can clearly record what it sees. The image processing application of the Raspberry Pi controller is used to convert the image to information.

 2. Body designing of our robot :

                                                 The body structure of our robot is designed in such a way that it remains compact but at the same time all the components are mounted on it and the objectives are also achieved. So, we have designed our robot with a centreal pivot point which helps in the obstacle crossing. The body material used is 5mm acrylic sheet. We have used acrylic sheets due to multiple reasons. The main reason was the weight constraint of the robot. We didnât want the robot to be a bulky body so we avoided using steel or wooden structure and used the acrylic one instead and also the object installation on acrylic is comparatively easier than wooden and steel bodies. To carry out the voltage supply constraint of the robot, we have used DC motors for our robot.Because AC motors require an AC power source, which is difficult to control at this scale, we chose DC motors because they have a more practical design approach. When it came time to choose a DC motor, we were concerned about the DC power source, so we went with a DC gear motor. The torque at which the motor runs is the next most essential quantity. There are several options here, but we’ll go with the one that comes with the MG996R Motor and has 2.5kg/cm torque. The motor’s torque of 2.5kg/cm means it can draw a weight of 2.5kg when suspended at a distance of 1cm.So if you suspend the load at 0.5cm, the motor can pull a load of 5kg, but if you suspend it at 2cm, the motor can only pull 1.25kg. The tyres used for the robot body are studded tyres. Treads promote tyre friction with the road by acting as a route for water under the tire’s surface, allowing the tyre to keep a tight grip on the road. The tread pattern on rubber tyres determines how much friction, or skid resistance, they have. Because a broader area of contact is available to create frictional forces under dry conditions on paved roads, a smooth tyre provides higher grip than a grooved or patterned tread. 

3. Wireless communication between robot and our controlling device:

          we have done it by using upper two explained scenarios.

Benefits of the Project

 Considering the difficult inaccessible location’s and critical work situation’s on the building construction site like deep excavated ground surface, between close spaced walls, Cramped up dark spaces within building elements like walls Or shafts, or over high levels like metal roofing sheets over PEB structures, outer elevation projections of building or Within metal ventilation ducts, utility ducts, false ceiling’s etc., such robots could easily reach such spaces and provide a proper view of the existing scenario and the constructed Work. This would not only provide ease of vision to technical Personnel’s but also provides safety and convenience of observing remotely. Also the Wi-Fi connection used for serial communication With the Android Smart phone will provide a robust & uninterrupted connection over longer range of distance efficiently and easily. The Android phone is available at cheaper cost and has a very user friendly interface making it easily operable by common user without much effort. Moreover, the robot can be operated by multiple android devices by various users without worrying to carry the remote controller along with the robot.

Technical Details of Final Deliverable

1)A wirelessly controlled robot that will provide a live footage and perform facial recognition in the area it is being sent to.

2)The robot can also cross obstacles like:

• Step

•Hump

•Depth

3)And taking the live footage with pi camera module and transmitted it wirelessly to  perform facial recoginition at our host device.
