“Strive for perfection in everything you do. Take the best that exists and make it better. When it does not exist, design it.”
-Sir Henry Royce
Base Idea: Develop an autonomous humanoid robot resembling the school mascot, showcasing that talents of the NAU Engineering Department
Sponsor: Louie Robot sponsored by Dean Andy Wang with the motivation being to inspiring future engineers to attend NAU
Design Features: Robot will be designed with movement, arm and hand gesturing, facial expressions, sensors for safety, rechargeable base, and built for expansion
Legacy Invention: Robot will incorporate a modular design with multiple fields continuing the innovation and design
What is benchmarking you might ask? Benchmarking is where our team evaluates current designs, products, and ideas in order to begin brainstorming. It is always essential to evaluate a starting point in any designing and inspiration can be obtained from a variety of places. Current humanoid robots have been developed for a variety of purposes such as assisting with natural disasters, sharing information, assistance with research, and to study human behavior. Below are figures and descriptions for our preliminary research!
Designed to mimic human behavior and provide entertainment [2]
This is a robot was designed to help with natural disasters [2]
Developed to research bipedal walking [1]
A quality function deployment, or QFD for short, is a design tool that cross evaluates criteria from a customer vs scientific engineering criteria. While designing is limited only by the imagination, feasibility and purpose must always be considered when brainstorming. Our team consulted with our client, Dean Wang, to gather a list of customer requirements and then created rough estimations of engineering values. These criteria are sorted into a table with weights and then ranked.
Now while the above QFD might just look like one giant table with random numbers, it allows engineers to focus and centralize design efforts. The QFD works by assigning the customer requirements on the left with a weight of importance 1 (lowest) to 11 (highest). These requirements are then evaluated against engineering requirements and their relative importance. For example, the height of the robot won't particularly affect safety which is why it was analyzed at a 3 but the aesthetic value and human representation are essential which is why they were analyzed at a 9 for importance.
Budgeting, is an essential part of any design planning. Although it would be ideal to be as rich as Tony Stark and develop with the finest resources available, engineers often must design with a financial plan in order for their design to be marketable and competitive. Our capstone team was fortunate to have a very flexible budget, courtesy of Dean Wang and the CEIAS department. Even with a flexible budget our team still planned accordingly and detailed expected finances.
