Activity 2.1.1b VEX Build

Introduction

An algorithm is a procedure or formula for solving a problem. A computer program can be viewed as an elaborate algorithm. In mathematics and computer science, an algorithm usually involvesa small procedure that solves a recurrent problem.

Engineers must communicate their solutions to a problem.Sometimes engineers communicate verbally and sometimes with written text and/or sketches. Communication is the tool that keeps all aspects of the design process on track. When the goal of a project is not shared or is not obvious to everyone, then communication falls apart and often the project is not completed within its constraints.

Today you will build a VEX model and then communicate to a partner exactly how to build the same model, given the same pieces.

Equipment

  • Gateway notebook
  • VEX structure and motion pieces, no more than 10 structure or motion pieces and 10 screws, nuts and washers, orrivets.
  • Bags

Procedure

  1. Using only the required number of VEX pieces, build a model.
  2. Do not show the model to your partner.
  3. Sit with your back to your partner. Your partner should have a bag of VEX pieces that matches the parts you used for your model.
  4. Verbally provide your partner with instructions to build a model that exactly matches your model.
  5. Compare your model to the one that your partner built.

Conclusion

  1. Did your partner make the model exactly as you expected?
  1. If you had written directions, what could you have done differently to ensure that the modelsbuilt were more consistent?
  1. What could your partner have done differently to ensure that your VEX object matched theirs?
  1. Which is an easier task for you, giving directions or following them? Why?
  1. Why do you think good communication skills are necessary for engineers?
