Robot Learns Navigation Skills Using Simulated Brain Cells

How are we as people able to navigate so well? We are a species of wanderers, after all, whose abilities of navigation have been finely tuned for over 200,000 years. According to neuroscientists, our ability to navigate has to do with two neurons which help us (and other animals) to geolocate naturally – “grid” cells and “place” cells.

The results: like a human, these robots began showing signs of natural navigation skills!

“Grid” cells are a relatively new discovery in our understanding of navigation. Discovered in 2005 by Edvard and May-Britt Moser at the Centre for the Biology of Memory (CBM) in Norway, grid cells were shown to help people understand their position in three-dimensional space. “Place” cells, however, were discovered in the 1970s by Nobel-winning neuroscientist John O’Keefe, and were shown to determine familiar spots in any given environment.

Once they set loose the robot in a 35-square-meter office space, the robot began showing signs of natural navigation, finding its way around the office over time without any human aid. When analyzing the basic neural network they engineered as the robot began navigating itself, they could see similar acts of artificial neurons firing off as they would in a biological brain.

FUTURE IMPLICATIONS

This opens up many avenues of research for the future of robotics, including those who may very well walk amongst us in a decade’s time, enjoying life as we’ve come to enjoy it as well.
