Chinese scientists have created a Frankenstein-like robot powered by a tiny human brain, a first-of-its-kind feat. The robot works by using a laboratory-grown brain organoid, a mass of cells, and a computer chip that interacts with the nervous system.
According to MailOnline, it has been described as a "brain on a chip" that functions like a human brain with the help of sensors and an artificial intelligence-based algorithm that drives the robot to move, grab objects, and avoid obstacles.
To create the artificial brain, a team of Chinese scientists used stem cells, a type of cell that forms brain tissue in the body. According to them, this brain shows signs of intelligence similar to the human brain by moving its limbs autonomously, and this could lead to methods of repairing damaged human cerebral cortex and creating other treatments for neurological disorders.

Scientists at Tianjin University have created a machine using brain-computer interfaces (BCI), which combine electrical signals emanating from the brain with computer chips.
This interface is the same system that was used to create Elon Musk's Neuralink chip, which was implanted in the patient's brain, allowing him to control the computer with his mind. The Neuralink device is powered by a special chip in the implant that processes signals and transmits them to a computer via a standard Bluetooth connection.
However, the Chinese researchers did not share how they transmit the signals to their organoid. The team said the technology still faces "bottlenecks such as low developmental maturity and insufficient supply of nutrients," which typically include antioxidants, fiber, and minerals.
When the organoids were grafted into the brain, they established a functional connection during the treatment with low-intensity ultrasound. Low-intensity ultrasound stimulation regenerates human tissue, forming neurons that send messages from the brain so that the robot can move autonomously.
The researchers explained that the robot has no eyes and only responds to electrical and sensory signals sent by the neurons.
The study is still in the early stages of development, and it remains unclear whether organoids can ever be used to repair or reconstruct damaged brain tissue.
