Core Skills Analysis
Science
- Will explored basic robotics principles by assembling mechanical parts and motors, linking physical components to functional movement.
- He applied the engineering design process—defining the problem, planning, building, testing, and iterating—while constructing the robotic dog.
- Will practiced programming logic using the LEGO Mindstorms visual coding environment, creating sequences, loops, and conditionals to control the robot's actions.
- He observed energy conversion, noting how electrical power from the battery drives motors to produce force and motion in the robotic dog.
Tips
To deepen Will's understanding, have him experiment with different sensor inputs (e.g., ultrasonic distance sensor) and program the dog to react to obstacles, turning the activity into a simple navigation challenge. Encourage him to research real canine locomotion and redesign the robot’s gait for smoother movement, documenting each design iteration in a lab notebook. Connect the project to a broader STEM context by exploring how engineers use robotics in fields like rescue, agriculture, or entertainment, perhaps through a virtual field trip or guest speaker. Finally, set a goal for Will to present his robotic dog’s capabilities to family or classmates, reinforcing communication and reflection skills.
