Core Skills Analysis
Robotics
- Will applied engineering design principles by selecting gears, motors, and structural pieces to create a stable four‑legged robot, demonstrating an understanding of mechanical advantage and load distribution.
- Will programmed the Mindstorms EV3 brick using block‑based code to coordinate leg movement, which reinforced logical sequencing, conditional statements, and debugging skills.
- Will measured and adjusted wheel‑to‑ground friction and motor speed, gathering quantitative data that aligns with concepts of ratio, proportion, and unit conversion.
- Will documented design changes and test results in a project log, practicing technical communication and reflective thinking.
Tips
To deepen Will's mastery, try a multi‑step challenge where he designs a new gait pattern for the dog to navigate a simple obstacle course, then records the robot's speed and compares it to the original design. Follow up with a collaborative brainstorming session where Will sketches three alternative body shapes and predicts how each would affect balance and battery life. Introduce a brief research segment on real‑world robotic dogs (e.g., Boston Dynamics Spot) and have Will present one similarity and one difference to his LEGO model. Finally, incorporate a peer‑review element where another student tests Will's robot and provides constructive feedback, reinforcing communication and iterative improvement.
