Design Scheme

D.1 Camera

It is used for facial recognition, pattern recognition and general photography as shown in fig.2 which later aids the computers in various aspects such as computing and security.

D.2 IR Sensor

It sends an IR beam which is then reflected back by the object forming an image to enhance the ability of the Rover to see (Fig.3). This will provide the Rover with thermal viewing capabilities that could aid in various sectors.

D.3 The Rover

It composes of 4 major components that are crucial for the working of the project.

● Raspberry Pi

● Arduino Uno

● Solid State Drive

● Bluetooth and WiFi Shields

D.4 Raspberry Pi

Secondary Brain as stated earlier, it is loaded up with Ubuntu on which the Chatbot is run using Python (Fig.4). The Raspberry Pi was used due to financial reasons and something like an Intel

NUC with the latest processors can run the program with greater rigor. The benchmarks are to be performed at the earliest and the results are to be updated. The Pi shares a hierarchical command over Arduino in execution of processes and more.

D.5 Arduino Uno

The Arduino (Fig.5) is used as a preliminary brain for the Rover. The main use is for the machine are locomotion, traversal of cameras (IR visible), color recognition, bluetooth and WiFi toggles and other basic operations that can be performed on a single processing unit.

D.6 Storage

A Solid State Drive (SSD) is used for Storage of data such as cognitive patterns, images, sounds and more. The reason for use of SSD (Fig.6) is primarily is for the unmatchable speed. The process that are involved are in need for quick reception and response.

D.7 Shields

The Shields that are used in the project are Bluetooth (Fig.7) and WiFi. The Bluetooth shield is used for general connections like pairing with devices in close proximity that are linked. The WiFi is used for connection with internet and other Rovers. The WiFi is used instead of Bluetooth for general purpose data transfer between the App and the Rover. In terms of Security the WiFi shields (Fig.8) can be used to hack into hostile domains by the police force or the military increasing a scope for the Rover from domestic to advanced provinces

D.8 Structure and Chronology

There are quite literally hundreds of open source CAD/CAM designs that can be 3D printed. The Raspberry Pi and the Arduino Uno are attached to the Rover as shown in fig.9 and linked with the Servos and Actuators. The IR camera and Microphone are attached at optimal places for maximum efficiency. The wheels are designed in a similar fashion to the famous Caterpillar track used in Army tanks. The Caterpillar tracks are used to climbing platforms and tread obstacles. The Rover moves by recognizing the obstacles on its path using its cameras. The Rover decides what obstacle to dodge and what obstacle to tread upon.

The system is build on the concepts of Stacks for data structure LIFO (Last In First Out) this enables the most immediate problem to be addressed first like a command to dodge a ball that is on trajectory to hit the Rover which could potentially destroy the cameras or sensors. At the initial stages of the build the Rover is controlled by an app in a mobile device [7]. At later stages when the Rover learns and creates a database the app wouldn’t be required. The process of building and working with a robot is very similar to nurturing a child once enough time and information is provided the child becomes capable of functioning on its own and after a point the Rover tends to your needs.

D.9 Charge Station

The charge station (Fig.10) is used to charge the Rover wirelessly by use of induction technology. The Rover simply parks on top of the station and the charging begins, by the time the battery is completely charged the process stops and the app is notified about the issue. The Rover rolls down once it is called upon or instructed to.
