Arduino is recognized as a solid platform for building autonomous robots, offering numerous I/O ports suitable for robotic control. However, users encounter challenges with storage and voltage limitations. To enhance functionality, combining Arduino with Raspberry Pi is suggested, where Arduino handles low-level tasks while Raspberry Pi manages higher-level operations, creating a robust system for robotics. WiFi connectivity expands storage options, and for powering high-voltage servos, additional controllers like power transistors or SCRs are recommended. While Arduino can be cumbersome for managing multiple servos and sensors, alternatives like the Pololu Maestro Controller provide a more user-friendly solution, allowing control of up to 24 servos and compatibility with common programming languages. Despite these improvements, memory limitations remain a concern, which can be addressed with mini desktop solutions.
