To make code readable, developers create a . This involves wrapping register commands into reusable functions. void motor_forward(int speed); int read_ultrasonic_sensor(); The Main Control Loop
Lack of automatic memory management means bugs like buffer overflows can cause physical damage to the hardware. Using C Programming a Robot
While powerful, C introduces specific complexities that developers must manage: To make code readable, developers create a
#include #define THRESHOLD 20 // Distance in cm int main() { // Initialize hardware init_motors(); init_sensors(); while(1) { // SENSE: Read distance from ultrasonic sensor int distance = get_distance_cm(); // THINK: Decision logic if (distance < THRESHOLD) { // ACT: Stop and turn stop_motors(); delay_ms(500); turn_right(90); } else { // ACT: Move forward move_forward(75); // 75% speed } } return 0; } Use code with caution.

The essence of robotics is the cycle. Below is a conceptual implementation of a simple obstacle-avoidance logic in C.
Handling multiple sensors simultaneously often requires Interrupt Service Routines (ISRs) to break the main loop execution when an event occurs.
Robots operate on a . Unlike desktop software that waits for user input, a robot continuously polls sensors and updates actuators in an infinite while(1) loop. 3. Practical Implementation: The Feedback Loop
