Members of the Shelton High School robotics team were among those at the Soupstock music and arts festival at Veterans Memorial Park (the Riverwalk) in Shelton.
Team members demonstrated how the their robots worked, including this one that can pick up a ball and throw it.
The Shelton High robotics team saw much success during the past school year, winning a New England regional tournament and traveling to the world championships in St. Louis.
Soupstock is now in its fifth year and raises money for the nonprofit Mary A. Schmecker Turtle Shell Fund, which promotes the education of young people in art, music, theater, skilled craft, and other creative pursuits.
The late Mary A. Schmecker had been active working with youth at the Lower Naugatuck Valley Boys & Girls Club, which has facilities in Shelton and Ansonia.
