Robotics Club: February 8, 2019

Introductions

On February 8, 2019, the Robotics Club re-started its second-semester meetings. The meeting was started by having the students Introduce themselves and share two important facts they would want others to know about them.

Engineering Design Process

The engineering design process is a series of steps that engineers follow when they are trying to solve a problem and design a solution for something; it is a methodical approach to problem-solving. 

After introductions, we discussed the concepts of the Engineering Design Process: Define the Problem, Research/Brainstorm, Draw/Design Solutions, Test/Record Date, and Communicate Results

Open-Ended Design Projects Versus Following Design Instructions

The club participants and I also talked about open-ended design projects vs. following design instructions.

Open-ended design in STEM has been shown to have a positive impact on retention, stimulates interest in engineering and enhances communication, team-building skills, and time management skills.

Last semester, students followed premade design instructions for robots that were designed for the specific purposes of the Lego Design team. This semester, students are using an open-ended design concept. At the beginning of each project, they work together to identify the goals and specifications for the project. Each project is designed to incorporate both aspects of technology that students have previous knowledge of and many aspects that they do not have knowledge of. This allows space to build structured lessons into the powerful format of individual creativity that must be used by each student to solve the Problem through their own Brainstorming, Designing, Building, and Testing phases of the process.

What did the students do?

During this first meeting, we defined our goals as Design, Build, and Test a robot that:

1. Moves autonomously exactly 1 meter
2. Uses at least 1 Motor
3. Uses wheels for locomotion
4. Displays the distance traveled on the robot’s screen

We covered how to translate basic robot controls (Turn Motor __ Revolutions) into real distances. This was done by measuring the circumference of the wheels that will be attached to the motors. We did these measurements together to master the skills. We used a couple of wheels, a string, and a ruler to measure the circumference. Then we proved through many trials that the circumference is equal to the distance traveled in 1 revolution.

Using this newfound knowledge will be valuable in the design and planning stages of club participants' solutions, along with other new knowledge and skills. We will also explicitly cover how to program the robot interface to display information gathered from the motors.  But FIRST…..We design!!

Our next meeting is February 15, 2019.
