This bad beast is in the form of stingray. It is made from the heart of a rat and its movement is controlled with the help of a blue light. 
Can't wait for the day when we can make a full bio engineered humanoid which can walk, talk and think like us. Man technology is getting cooler day by day.  Kevin Kit Parker first came up the idea of taking apart a rat's heart and transforming it into a tissue-engineered stingray during his trip to the New England Aquarium.

After just four year, a robotic cyborg ray that swims towards the blue light is making some wave in our boring looking Science magazine and is pushing the limits of what's possible in the design of machines powered by living cells.
Parker directed a team of exceptionally talented scientist at Harvard University A research team based at Harvard University's Disease Biophysics Group, which created the translucent, penny-sized ray with a gold skeleton and silicone fins layered with the heart muscle cells of a rat.
It's remote-controlled, guided by a blinking blue flashlight. Each burst of blue sets off a cascade of signals through the cells, which have been genetically-engineered to respond to light. The contraction of the tissue creates a downward motion on the ray's body. When the tissue relaxes, the gold skeleton recoils—moving the fin upward again in an undulating cycle that mimics the graceful swimming of a real ray or skate.
Parker, whose research includes cardiac cell biology, launched the project as a method for learning more about the mysteries of the human heart and a step toward the far-off goal of building an artificial one. But the interdisciplinary project is also sparking interest in other fields, from marine biology to robotics.

The total cost of turning this dreamy project into a reality was much more expensive than they previously thought. It cost them close to $1million to complete the whole project. A mechanical engineer by training, Park had to delve into molecular and cell biology. The team pulled experts from diverse fields, including an ichthyologist and someone who studies fish to understand and help replicate a ray's muscle structure and biomechanics.

Terminator inspired robots aren't new. A precursor to the stingray was a tissue-engineered jellyfish Parker helped create in 2012, also with the aim of understanding the muscular pumping of a heart. But one of the robotic stingray's most intriguing contributions is that by putting in the light control they have a way of controlling the cell without a nervous system.
Park and his colleagues built more than 200 of these tiny creatures during years of research but they cant put them into any pipe or ocean as they can only swim in a pool of warm liquid solution filled with sugar and salt. The cells couldn't survive outside of a dish and weren't designed to, though Long said it would be possible to give a similar creature a skin that wraps up the solution and creates a kind of circulatory system. Battery power is a big challenge for robots, especially for tiny, lightweight machines.
