Mr Raj, who claims a keen interest in Artificial Intelligence (AI), says he builds robots for a living and returned to his lab to see how he could help the dog. The solution, he said, was an AI-controlled robotic arm attached to a giant drone.
He says he returned to the open drain about six hours later and sent the improvised aerial vehicle to do its job - controlling the drone carefully from outside.
"The AI helped me monitor the animal's heart rate, If the grip was too tight, the pup would suffocate," he said.
A video shows the puppy mid-air in the clutches of the robotic arm. Using the drone, Mr Raj flies the puppy across the road, before releasing the grip of the robotic arm.
"When it was on the ground, it vomited plastic including paan masala packets that people had carelessly tossed into the drain," Mr Raj claimed.

There was plenty of praise for Mr Raj, but the video also provoked skepticism on social media.
It could have been done faster and easier with a ladder and rope instead. This is a classic example of wasted engineering.— Jairaj (@jairajs) May 3, 2018
Impressive how clean the puppy came out of the drain. My dog years ago used to fall often into drains and soak pits (don't ask) and he would always call me out black and smelly. And how was the harness slid over the dog's belly and tightened? Very impressive feat.— Subramanian Sharma (@KannanSharma) May 4, 2018
Good he saved! Was he experimenting? Why couldn't use help from firefighters?— Muhammad Khaleel (@khwleel) May 3, 2018
Good for him saving the pup and all but I feel like a ladder would have been faster, cheaper, and easier than building an AI arm to lift the dog out.— William Trusher (@WillTrusher) May 4, 2018
Mr Raj's humanoid robot was one of the prime attractions at February's Uttar Pradesh Investors' Summit. The trilingual robot, fluent in Hindi, English and Sanskrit, welcomed Prime Minister Narendra Modi and UP Chief Minister Yogi Adityanath among other guests to the event.Click for more trending news
