Robotic Arm Design Challenge Lesson Plan
Title: Robotic Arm Design Challenge Date: Fall 2025 Author's Name: Dan Thomas and Dr. David Burghardt Grade Level: 7/8 Content or Subject Area's: Informed engineering design with computer science and computer control Duration: 8 days (40-minute periods)
General Objectives:
Students will design, construct, and program a robotic arm made from cardboard that includes at least three joints powered by servo motors from the Hummingbird Kit, capable of performing an automated motion sequence to move an object from Point A to Point B using the informed engineering design process.
Learning Outcomes:
After completion of the lessons, students will be able to: 1. Use the informed engineering design process 2. Program positional and rotational servo motors using Birdbrain Snap to create coordinated multi-joint movement sequences 3. Design and construct a functional robotic arm prototype with multiple degrees of freedom using cardboard and brass fasteners 4. Apply iterative testing and refinement to optimize mechanical stability and programmed motion accuracy
