Halloween at Tufts is always marked by festive costumes and  spooky decorations in dorm rooms. This year, a few ambitious freshmen decided to have some Halloween fun in the classroom, too – students in Professor Ethan Danahy’s “Simple Robotics” course created a haunted house using LEGO robotics. The haunted house was an effort to show off the skills they’ve acquired this semester while having a little nerdy – yet decidedly spooky – fun.

The project, supported by Tufts’ Center for Engineering Education and Outreach, was open to the public on October 31. Check out the video below to see these haunted LEGO robots in action!
