Scale and 3D printing Robots

Engineers and researchers use scaling to study, create and design models to help society. Because engineers can't often make something the exact size, engineers will often use scaling when making a prototype.

You can scale up and down. What are some objects that would be scaled up? Scaled down?

Introduction to TinkerCad 3D software

Another good tutorial for TinkerCad

Working in groups of two you will measure all the parts, in inches, of a random robot that is given to you. 

GOALS: 

Understanding Scale

Use a spreadsheet to make the job easier

Learning 3D Software Tinkercad

Understanding how to use the 3D printer

You will design a robot to scale using Tinkercad and will print it on the 3D printer. 

CRITERIA:

• 1. THE MAIN CRITERIA FOR THE 3D MODEL IS SCALING THE MODEL TO BE BETWEEN 3 AND 4 INCHES, CLOSER TO 3 INCHES. The final size of the 3D should be closer to 3 inches.

  2. An issue you will run across is that the units you will be working with in the 3D software Tinkercad is millimeters. 2.54 cm equals 1 inch

  3. You will need to use a spreadsheet to keep track of your data, convert your measurements from inches to millimeters and to calculate the height measurement of a triangle/diameter of a sphere.

  4. If your robot has a triangle you will use the Pythagorean Theorem to calculate the height of the equilateral triangle to help with the measurements in Tinkercad. A^2+B^2=C^2

  5. If your robot has a sphere you will use the circumference to calculate the diameter to help with the measurements in Tinkercad. C=2(3.14)r

You will work with a partner but each person will submit to Google Classroom your own spreadsheet. Each person will design a scaled robot in Tinkercad. We will print ONE of your robots.
