2.007: Introduction to Robots, Design and Manufacturing I

In 2.007, we are introduced to design and manufacturing by building a robot to complete various tasks on a "game board" or obstacle course.

Through this class, I developed competence and self-confidence as a design engineer through an emphasis on the creative design process bolstered by application of physical laws. I completed the project by active learning via quick prototyping while remaining on schedule and within budget. Robustness and manufacturability were heavily emphasized. I learned about idea generation, estimation, concept selection, visual thinking, computer-aided design (CAD), mechanism design, machine elements, basic electronics, technical communication, and ethics. 

Strategy

My strategy was to pick up the flag and then raise it, and place it on top of the light tower pillar (pictured below).

My Design

• Motor system

• Chassis System

  • Front wheel 

  • Motorized back wheels

• Scissor Lift System

  • Actuating System

  • Bearings and Joints

  • Aluminum rods

  • Aluminum framing

• Flag Holder

• Flag extender

This required accurate positioning in the box before the round started. 

Design Requirements

• Lift the system to the stop of the pillar

• Place the flag onto the top of the pillar

• Drive Forward

• Reduce the bounce of the robot when the scissor lift fully extended

• Keep the flag attached to the robot

• Move the Lanterns    

Lessons Learned

• Prototype as much as possible

• CAD everything first to make sure it works when you finalize your design

• Simple is better

• Prepare as much as possible for the worst to occur, time management is key
