Rat brain robot at University of Reading
Article by Max Hawkins
Amazing. The team over at the University of Reading, fronted by Kevin Warwick, a professor who is an expert in the field of robotics, and who brought us the excellent Real Robots series have done it again. This time, it is in the form of a biorobot called “Gordon”, who has a tiny biological brain made from cultured rat neurons. Why is it so special? Warwick’s team are experts in their field, especially regarding artificial intelligence, and this could open up many doorways into how brains work which could help progress the research and development of AI in the future.
But it also opens up to a whole different possibility for research into medical conditions, such as Alzheimer’s Disease. If they can discover how the brain works in the robot, they could develop ways of curing diseases like this which are currently devastating to those who suffer from them.
Interestingly enough, the robot uses a Bluetooth connection to communicate with it’s own “body”, with no control from humans or computers. It does however, require external stimulation for it to function.
Professor Warwick noted some interesting things about the robot while explaining the project
“Within about 24 hours, they start sending out feelers to each other and making connections,” said Warwick.
“Within a week we get some spontaneous firings and brain-like activity” similar to what happens in a normal rat — or human — brain, he added.
“Now we are looking at how best to teach it to behave in certain ways,” explained Warwick.
The great thing about this robot is that it learns from it’s sensors, like if it collides with something, it will learn from this and will help it prevent the same thing happening again. The great thing again is the robots they have developed before also exhibited the same behaviour, using ultra-sound and light sensors to detect where it was and prevent it from driving into things.
My favourite quote from Warwick, which makes “Gordon” eerily “real” in the sense, is this.
Gordon, in fact, has multiple personalities — several MEA “brains” that the scientists can dock into the robot.
“It’s quite funny — you get differences between the brains,” said Warwick. “This one is a bit boisterous and active, while we know another is not going to do what we want it to.”
Kevin Warwick is know for having a couple of silicone chip implants in his arm, which allow computers in buildings to track where he is at any time. Creepy, but he is man enough to go through with it. Keep up the great work, Kevin.
