Engineering: Design Thinking in Action
Engineering is all about solving problems, and VEX Robotics provides a perfect platform for budding engineers to hone their skills.
The Engineering Design Process
VEX Robotics naturally follows the engineering design process:
1. Define the Problem: Students start with a clear challenge or goal for their robot.
2. Research: They investigate possible solutions and learn from existing designs.
3. Brainstorm: Teams come up with multiple ideas for their robot design.
4. Choose a Solution: Students select the most promising design to pursue.
5. Build a Prototype: Using VEX components, students bring their design to life.
6. Test and Evaluate: Robots are put through their paces in various challenges.
7. Iterate and Improve: Based on test results, students refine their designs.
This process teaches students that engineering is iterative and that failure is a stepping stone to success.
Classroom Idea: Organize an “Engineering Showcase” where student teams present their robot designs to a panel of judges (which could include teachers or older students). Each team gives a short presentation explaining their design process, the challenges they faced, and how they overcame them. The judges can ask questions and provide feedback, simulating a real-world engineering review process. This activity not only reinforces the engineering design process but also helps students develop presentation and communication skills crucial in STEM fields.
Mechanical Engineering Principles
Building robots introduces students to key mechanical engineering concepts:
