A robot car, also known as an autonomous car or self-driving car, is a vehicle that is capable of sensing its environment and navigating without human input. Robot cars use a combination of sensors such as cameras, LiDAR, radar, and ultrasonic sensors to perceive their environment and make decisions about their movements.
Robot cars use advanced algorithms such as computer vision, machine learning, and path planning to process sensor data and make decisions about their movements. They can be programmed to follow a specific path, avoid obstacles, and respond to traffic signals and other road signs.
There are different types of robot cars, such as fully autonomous cars that can drive themselves without any human intervention, and semi-autonomous cars that can assist the driver with certain tasks, such as steering and braking.
Robot cars have the potential to improve safety, reduce traffic congestion, and make transportation more efficient and accessible. However, there are also concerns about the safety, reliability, and ethical implications of robot cars.
A robot car with an ESP32-CAM is a type of robot car that utilizes the ESP32-CAM module as a means of sensing its environment and making decisions about its movements. The ESP32-CAM is a small module that includes a microcontroller, a camera, and a built-in wifi, which makes it well suited for use in a robot car.
The ESP32-CAM can be used to process images and video from the camera, and use computer vision algorithms to detect and track objects, such as pedestrians, other vehicles, and traffic signs. The built-in wifi can be used to stream the camera’s output, or to connect the robot car to a network for remote control and monitoring.
The ESP32-CAM can be programmed using the Arduino IDE, which supports the ESP32 platform. In order to control the movement of the robot car, it should be connected to motor drivers or other motor controllers that can be controlled by the ESP32-CAM. It could also be paired with other sensors like LiDAR, ultrasonic sensors, etc.
It is possible to order a car equipped with an ESP32-CAM via a wifi connection. However, it would require significant customization and integration work to equip a car with an ESP32-CAM module, as well as the necessary software and algorithms to process sensor data and control the car’s movements.
Currently, there aren’t any mass-produced cars that come equipped with an ESP32-CAM module and the necessary software to make it a self-driving car. The car manufacturers and third-party developers are still working on integrating such technology in cars and making it available to the public.
A better option would be to purchase a kit or a DIY project that allows you to retrofit a car with an ESP32-CAM module and the necessary hardware and software to make it a robot car. There are a few companies that sell such kits, however, these projects are intended for hobbyists, students, and researchers and might not be legal or safe to use on public roads.
In this project we will make a car equipped with a camera remotely controlled (Wifi) by a computer with the ESP32-CAM card.
The user controls the car through a simple web browser which displays the video stream transmitted by the IP camera of the ESP32-CAM card and the direction buttons (forward, right and left).
The Arduino UNO is a microcontroller board based on the ATmega328P microcontroller. It has 14 digital input/output pins, 6 analog inputs, a 16 MHz quartz crystal, a USB connection, a power jack, an ICSP header, and a reset button. The board is equipped with sets of digital and analog input/output (I/O) pins that may be interfaced to various expansion boards and other circuits. The board can be programmed with the Arduino software (IDE), which is available for free on the Arduino website.
The Arduino UNO is a popular choice for beginners and hobbyists as it is easy to use, has a large community and a wide range of libraries available, allowing for easy integration of sensors, actuators, and other devices.
The Arduino UNO can be connected to a computer via a USB cable, and the Arduino IDE can be used to upload the code onto the board. Once the code is uploaded, the board can function independently, even without the computer being connected.
The ESP32 CAM is a small module based on the ESP32 microcontroller and an OV2640 camera. It is designed for applications such as IoT and home automation, and can be programmed using the Arduino IDE or other platforms. It has built-in WiFi and Bluetooth capabilities, and can be used for tasks such as image and video capture, facial recognition, and object detection.
A 2-wheel car robot kit is a collection of components that can be used to build a small, autonomous robot that moves on two wheels. These kits typically include a microcontroller, such as a ESP32 card, to control the robot’s movements, as well as motors, wheels, and other hardware to enable the robot to move and navigate.
2-wheel car robots are often used as educational tools, as they can be used to teach basic principles of robotics, electronics, and programming. They can also be used as a platform for experimenting with different control algorithms, sensors, and other hardware.
This robot kit is composed of:
2 gear motors (1:48)
2 car tires
1 universal wheel
A relay is an electrically operated switch that is used to control a DC motor. The relay acts as a control circuit and is used to turn the motor on and off. When the relay is activated , it closes a set of contacts that allow electrical current to flow to the motor, causing it to turn on. When the relay is deactivated (or “de-energized”), it opens the contacts, cutting off the electrical current to the motor, causing it to turn off. The relay can be controlled using a variety of methods, such as a switch, a microcontroller, or a sensor.
A 9V battery is a type of primary battery that typically provides a voltage of around 9 volts. These batteries are commonly used in a variety of electronic devices such as smoke detectors, portable radios, and remote controls. They are also used in the low power electronic devices.
