Sustainable League of Combat Robotics
The Sustainable League of Combat Robotics (SLCR) is a hands-on robotics competition league that emphasizes the use of sustainable, affordable materials, with the majority of the combat robots built from 3D-printed parts. SLCR offers a platform for students and educators to engage with STEM concepts by designing and building 1lb Antweight Class robots, competing in events throughout the year. The league promotes learning in areas such as electronics, 3D design, manufacturing, and engineering, while culminating in the annual Plastic Pandemonium competition.
