Using SolidWorks to design Boe-Bot



Using SolidWorks to design Boe-Bot

There are multiple parts to this assignment.

1. Determine the surface area of the base of the Boe-Bot using the formulas below.

2. Build the base.

3. Build a side, copy.

4. Build the ends separately.

5. Assemble the Boe-Bot using the models you have drawn to represent an actual representation of the Boe-Bot. Show an exploded view of your project.

Math Variables

• Length of base, LB

• Width of base, WB

• Height of base, HB

• Area of base, AB

• Volume of box, VB

• Surface Area of box, SB
