 ## The Body
 Using the same analogy, the body of the Alvik robot includes everything else from the sensors and motors to the connectors supporting external modules and, of course, the STM32, which acts like the nervous system of the robot. Just as the human nervous system transmits signals between the brain and various parts of the body, the STM32 transmits commands and collects data from the robot's components. When the Nano ESP32, acting as the brain, sends commands, the STM32 executes these low-level operations, such as moving the motors, flashing the LEDs, or interacting with external devices. The STM32 is essential for carrying out the detailed actions based on the high-level instructions from the Nano ESP32, ensuring that the robot's movements and functions are performed accurately.

 The main core of the robot is the STM32 ARM Cortex-M4 32 Bit controller. It handles the low-level commands such as reading sensors and moving motors. You can access it through a set of dedicated APIs from the Nano ESP32.
