Assignment #5

COMPONENTS

Problem Statement

Robotics is an increasing factor in modern day automation. As the cost of hardware decreases, providing long term benefits over its opposing counterparts, technology continues to replace tedious tasks once operated by humans, doing so more efficiently with less percent error. For example, Amazon has thousands of robots that work within their warehouse to organize their products for distribution. What is interesting about these robots is that they can move heavy pallets and pivot with immense control. But what if they didn’t have to pivot at all?

For this assignment, I will be designing a multi-directional (agile) part that will enhance the wheel’s degree of motion. Build dimensions are not limited to a certain criterion, however, part dimensions and portions must be logical. Object must be designed to enable a vehicle to maneuver vertically, horizontally, and diagonally to be considered agile. Object must be agile.

Assumptions

For this project, we can assume that any material and machine process may be utilized for creative purpose of the assignment. Concepts are under the impression that a 12v DC motor is integrated. Functionality is the focus for this project; object is assumed to be under light load and will not be calculated. Robot is assumed to only operate on smooth surfaces, under normal conditions.

Decision Matrix


For this decision matrix, the main criteria consist of; cost, weight, safety, design, agility, assembly, efficiency. Each category was given a rating between 1 and 5 with 5 being the highest rating. Functionality was a focus for this project so as sub criteria, agility was rated the highest at twenty-five percent. Safety was rated the same since the product is being marketed to a consumer. Next, all weighing in at ten percent, are cost, assembly, and efficiency. All three are necessary considerations and were given with an evenly distributed weight. Lastly, there is the weight of the object. It is not as important in terms of functionality, but weight can contribute to the amount of material used (cost) and agility if it is light which is why it’s considered.

Lessons Learned

It’s been a while since I’ve made a complete assembly on SolidWorks. For this model I was able to create multiple sub-assemblies to construct a final model. As shown in the components section, I was able to re-use the same base model to represent different components which were defined as sub-assemblies. This was useful because it meant that I didn’t have to re-construct different models for each component; saving me time and effort.

Colby, Garrett
Those solids problems are pretty dope. Again, I like the animations that you provided; it helps me diverse myself in your vision. Your calculations are always very supportive of your design. Kudos!
Hanna, Nicholas These renders are awesome, especially the full assembly. I like how you listed the multiple components and had a picture of the fully built product at the end. I’m hype for when you actually build this.
