Love must really “byte” for a tech geek who paid tens of thousands of dollars to build a realistic robot replica of actress Scarlett Johansson — which is programed to giggle, wink and flirt with him.

Ricky Ma, 42, of Hong Kong, spent $50,000 to create the creepy lifelike automaton using a 3D-printed skeleton, a computer and expensive silicone skin.

Hollywood’s hottest humanoid is life-sized, makes facial expressions and responds to verbal cues — simulating a connection that’s, well, electric.

When Ma tells the robot she’s beautiful, she is programed to grin and say, “He-he, thank you.”

He says he spent a year and a half toiling over the mechanical movie star to fulfill a childhood dream.

“When I was a child, I liked robots,” he said. “I liked watching animation. I figured I should just do it when the timing is right and realize my dream. If I realize my dream, I will have no regrets in life.”

Ma, a graphic designer, had to teach himself the skills to build the gadget, which was plagued by electronic glitches — and which made him the target of ridicule .

“During this process, a lot of people would say things like, ‘Are you stupid? This takes a lot of money. Do you even know how to do it? It’s really hard,’ ” Ma said. “When you look at everything together, it was really difficult.”

But he definitely thinks it was worth the trouble — because humans will rely more on robots in the future.

Ma, who plans to write a book about the project, nicknamed the prototype robot Mark 1.

Scarlett Johansson the robot rocks blond hair, an exposed midriff and a short gray skirt, while the human Johansson played a robot in the Oscar-winning movie “Her.” A rep for the star didn’t respond to a request for comment Friday.
