Arriving at CMU we checked in with "Tank" the roboceptionist and then it was off to the races.
The view from the finish line shows the challenge facing today's racers.
The crowds were out in PGH for race day at Carnegie Mellon University School of Computer Science's 24th Annual Mobot Races. The weather was beautiful but challenging for the line followers with bright sunshine and passing clouds.
The mobots were equipped with sensors ranging from infrared color sensors to webcams doing line detection in OpenCV.
Some were equipped with sensors to detect the gates for navigating the course.
Passing clouds caused issues for mobots using IR sensors for line detection.
