The very first Chester County Intermediate Unit STEM Expo last Friday had its own celebrity. Milo the Robot for Autism was a hit with the crowds, which included educators who were there to explore STEM innovations. The event, where multiple vendors presented robots and other technology gadgets meant to help children learn, was held May 3 at the Chester County Intermediate Unit in Downingtown. Milo was a particular popular fixture because of the robot’s ability to display life-like emotions, with the goal of helping autistic children respond and learn from certain facial cues. Organizers say the event’s goal was to show educators a variety of innovative learning tools that have applications in science, technology, engineering, and math. According to its web site, the Chester County Intermediate Unit provides services to the 12 school districts in Chester County. This includes services to nearly 86,000 public and non-public school students and over 6,000 educators.
