                     The choice of communication protocol in robotics is a strategic decision based on the specific needs of the application.
                     UART is ideal for simple, point-to-point communication. I2C is excellent for connecting multiple low-speed sensors to a
                     single controller with minimal wiring. SPI shines in high-speed data transfer scenarios where a single master controls
                     multiple slaves. And finally, CAN is the go-to protocol for robust, reliable, and fault-tolerant communication in demanding,
                     real-time multi-master environments like autonomous vehicles and industrial machinery. Understanding these protocols
                     is fundamental to designing and implementing efficient and reliable robotic systems.

                                                        The Future of AI and Robots is Human Collaboration
                                         The most exciting part about robotics and AI isn’t that they’ll replace humans—it’s that
                                         they’ll work with us. Collaborative robots, or “cobots,” are already in factories, helping
                          BRAINY            workers instead of replacing them. AI assistants support doctors, teachers, and

                                        even farmers, amplifying human capabilities. The real future isn’t about humans versus
                                         robots—it’s about humans and robots teaming up to solve the biggest challenges, from
                                                               climate change to space exploration.

                     Power Requirements of Robotic Components: The Energy Demands
                     Every component within a robot requires electrical energy to perform its function. The amount of power (measured in
                     watts, where Power = Voltage × Current) or current (measured in amperes) consumed by each component directly
                     impacts the robot’s overall energy budget.
