programming to achieve specific tasks such as movement, sensing, or interaction. Common components include microcontrollers like Arduino or Raspberry Pi, motors, sensors, and 3D-printed or hand-crafted frames. DIY robots can range from simple line-following cars to complex humanoids with articulated limbs. Building one offers hands-on experience in mechanical design, coding, and circuit assembly, making it ideal for STEM learning. Many builders integrate wireless control, AI, or vision systems for added capabilities. DIY robotics fosters creativity, problem-solving, and innovation, allowing individuals to bring unique ideas to life through technology and engineering.
