Autonomous vehicles can control and navigate themselves, "in the
absence of a human being," said associate professor of biomedical engineering and electrical and computer engineering Wolfgang Fink.
"Fink has been developing an autonomous rover, which can be controlled
with an iPhone or iPad. The vehicle can also use LiDAR, a kind of laser
sensor, to recognize obstacles or to follow someone around. The vehicle
is further equipped with cameras, which use algorithms to determine
what items within range are of interest to the rover."
