Gravity: Arduino Shield for Raspberry Pi B+/2B/3B/3B+/4B

Yes, that's correct. Raspberry Pi is a mini computer that runs on a Linux operating system, while Arduino is a microcontroller that runs on simple input/output (I/O) instructions. This means that the Raspberry Pi is more powerful and has a more complex operating system, while the Arduino is designed for simpler, more specific tasks. As a result, the Raspberry Pi is generally better suited for tasks that require more computational power, such as running applications or hosting websites, while the Arduino is better suited for tasks that require precise control of hardware, such as interacting with sensors or controlling motors. Both the Raspberry Pi and Arduino are popular choices for DIY projects and are widely used in a variety of applications.

 

The Raspberry Pi can be used to add vision capabilities to the robot, such as using a camera to stream video or process images, and to provide a display for the robot's operator. Meanwhile, the Arduino can be used to control the motors and other hardware, such as sensors, needed for the robot to navigate and perform tasks. The Arduino's lack of an operating system and its ability to process instructions quickly make it well-suited for handling real-time tasks such as obstacle avoidance. The Raspberry Pi, with its more powerful processing capabilities and support for wireless communications, is well-suited for tasks that require more computational power, such as running complex algorithms or processing images. By using both the Raspberry Pi and Arduino together, it is possible to create a mobile robot that has a range of advanced capabilities.
