Robot 1

Description

Robot 1 is a two-wheeled inverted pendulum designed to demonstrate real-time feedback control and dynamic stability for K–12 STEM outreach. The robot actively balances itself by measuring its tilt angle, computing corrections through a PID controller, and adjusting wheel motion to stay upright. This allows students to interact with the robot physically while observing how control systems respond to disturbances.

The mechanical frame was designed for durability and portability, meeting strict safety and impact requirements including a 30-inch drop test. The system integrates an Arduino-based controller, dual DC motors with encoders, a potentiometer or IMU for tilt sensing, a layered chassis for organized electronics, and optional touchscreen or user-interface elements for classroom interaction. All components were selected to be low-cost and mass-producible for deployment in the Robotics Traveling Van outreach program.

This prototype serves as a hands-on demonstration of core engineering concepts such as system modeling, instability, feedback loops, and controller tuning. It also lays the foundation for future enhancements, including expanded data visualization and improved user interaction for classroom demonstrations.
