TechNova on Instagram: "A self taught inventor has built a fully functional robotic heart using nothing but machine parts, showing how far raw engineering skill can go when creativity meets precision. He used motors, valves, gears and recycled auto components to mimic the rhythm and circulation of a real human heart, creating a system that pumps fluid with lifelike timing and control. The entire device runs on mechanical forces without silicone or biological material, turning a workshop project
