Scientists have crossed the robot and the brain: the movements of the wheel platform to wirelessly control a ball rat nerve cells floating in the nutrient solution. The perfect fantasy.
Responsible for the new product, the famous British professor Kevin Warwick (Kevin Warwick), «the first cyborg in history." More than ten years ago, he implanted himself simplest RFID-chip, and afterwards — and a better chip.
With his team of researchers grew rat neurons Warwick on an array of 128 electrodes, which are controlled by a simple moving robot. The electrodes transmit signals from sonar and transmit commands to control the movement of the machine. No microprocessor control provides all live rat "nedomozg." Interestingly, in principle, nothing limits the further growth of neurons, and thus being can become more complex in their reactions.
To achieve this, the researchers isolated neuronal cell embryos and placed on a chip, on which he grew up. Just a few minutes neurons matured, forming together the first communication — and in a few days, this conglomerate can reach up to hundreds of thousands of nerve cells. After that, the scientists began to explore the interconnectedness of neurons in the network. Sending a signal to one of 128 electrodes, they were watching, he excites neighboring neurons, and they convey excitement to his neighbors — until the current is not detected at the other electrode.
Having established these relationships, the researchers connected the electrodes to the corresponding electrodes simple robotic platform. More specifically, the connection is not direct himself the "brain" is in the nutrient solution, and receives signals and sends commands via Bluetooth. He might be living in a virtual "matrix", fully aware of yourself (unless, of course, he himself recognizes) residing on a moving platform.
When the sonar signal received on the approximation of the obstacles — for example, the walls — it wirelessly receives an incoming electrode "brain", which handles the signal and produce an effluent electrode reaction, which, again by Bluetooth, comes to the wheels of a moving platform. As you repeat these exercises communication between neurons, as expected, stronger, efficiency and speed of the robot grows, he rarely encounters obstacles.
Now the scientists are going to make your being more complex and skillful. They want to grow the "brain" of 30 million neurons (for comparison, in our brain to approximately 100 billion) — and then, perhaps, really to experiment with human nerve cells. But the politicians will decide whether such a creature have all the rights of a citizen, obliged to serve in the military, and whether to vote.
