  • Boy Scouts students visited our laboratory for an engaging educational session led by Dr. Vinnakota and his team. The visit included two merit badge workshops:

    1. For the Electricity Merit Badge, participants learned essential safety measures during electrical storms, how to interpret a home electricity bill, steps to take during an electrical fire, and built simple circuits, an electrical buzzer, and a DC motor through hands-on activities.

    2. For the Robotics Merit Badge, students constructed an obstacle-avoidance robot using fully 3D-printed parts and programmed a microcontroller to enable the robot to navigate obstacles effectively.

    These interactive sessions provided valuable STEM learning experiences for the Boy Scouts.
