Scientists at a University in Berlin are using the honeybee nervous system as a model for a robot brain. They installed a camera on a small robotic vehicle and connected it to a computer, which acted as the insect brain. The camera acted as the eye and the neural network operated the motors of the robot in order to control its direction. The scientists set up a reward system associated with colored objects to lead to specific changes in the network--teaching the insect-brained robot to go for the reward and avoid the other option. And the little insect robots did it! Success! Now these scientists plan to expand the neural network by supplementing more learning principles.
