Project Title
TEAM ZERO
Abstract
Team Zero's Self driving RC car, as the name states, is an autonomous vehicle designed to navigate to a given specified destination successfully, avoiding obstacles along its way. The car's infrastructure is built upon four key components: the Driver, Sensor and Bridge, Geo, and Motor nodes, which communicate internally via a CAN Bus and with the user via a mobile app. The vehicle continuously senses and processes all the information from these nodes to make decisions to ensure it stays on course and reaches its destination. It is built on a hobby-grade RC car chassis, modified with the necessary components and adjustments to fulfill its primary objectives of autonomous navigation and obstacle avoidance.

The HC-05 Bluetooth module is a widely used and versatile wireless communication module that enables Bluetooth connectivity using its Serial Port Protocol. Key Features HC-05 Bluetooth Module:
Bluetooth Standard:
The HC-05 Bluetooth module operates on Bluetooth version 2.0 + EDR (Enhanced Data Rate), supporting reliable and efficient wireless communication.
Operating Modes:
The module can operate in both Master and Slave modes. In Slave mode, it can pair with other Bluetooth devices, while in Master mode, it can initiate connections.
Communication Range:
The HC-05 is classified as a Class 2 Bluetooth device, providing a communication range of approximately 10 meters (33 feet). This makes it suitable for short to medium-range applications.
Serial Communication:
It communicates with other devices using a serial communication interface, making it compatible with microcontrollers like Arduino. The module typically supports standard baud rates like 9600 bps.
AT Command Configuration:
The HC-05 Bluetooth module can be configured using AT commands, allowing users to customize various parameters such as the device name, pairing code, and operating mode.
Voltage Compatibility:
The module operates within a voltage range of 3.6V to 6V, making it compatible with a variety of power sources.
Security Features:
The HC-05 supports basic security features, including the ability to set a PIN code for pairing and configuring security modes.
LED Indicator:
Many HC-05 modules have an onboard LED indicator that provides visual feedback on the pairing status and communication activity.
