I was teaching over 100 small children about robotics for National Robotics Week last year at the Oceanside Boys & Girls Club;
Then from watching the children really learning I realized that I could build them a little robot to play with;
Step 1: The BallBot1 Robot Is Born ...
The BallBot1 was born;
Step 2: Exploring Other Body Designs ...
Step 3: Accessible Mods ...
Step 4: Begin Printing ...
Step 5: Print Quality Less Than Desired ...
Step 6: Another Printer ...
Step 7: Prettier Results ...
And I'm seeing my designs from a new angle; http://www.brainless.org/R2Pv1.net/BallBot1.Project/Wheels4BallBot1Pc.gif
Step 8: ABS Plastic Is Maybe Better for Consumer Products ... Where's the Colors?
Step 9: Hand Painting Is for Naught!
and as you can see I'm not very good at hand-painting in the features;
Step 10: How to Create a 3D Model Using SolidWorks ...
Here's a quicky lesson;
File - New - Part
Sketch Tab - Sketch - Select any Plane
Select a basic tool like the circle ... then select the red triad origin in the middle of the screen
1-Click the mouse changes - move the mouse away from the center and see your circle grow ... click to stop growing.
Now hit the ESC key to exit the tool.
Now select the Smart Dimension tool next to Sketch ... click on the outer edge of the circle and move the mouse around and pick a style size label and click again.
Type in the diameter of the circle you want and hit ENTER
Now select the solid straight line tool ... moving your mouse near the bottom of the circle you will see the mid-point highlight ... click on that then drag your mouse to the top mid-point of the circle and click again ... then hit ESC to exit the tool.
Now click on the Trim Entities tool ... using the left mouse button held down drag it over the left half of the circle but DO NOT cross the vertical middle line ... then let go of the mouse. You have now made a half-circle. Hit ESC to exit the Trim Tool.
Click on Exit Sketch in the upper left corner.
Click on the Features TAB
Click on the second tool "Revolved Boss/Base"
Now click on the vertical bar in your half-circle sketch and see it turn into a ball.
Click on the GREEN check mark either in the upper left or the upper right of the screen to exit the tool and see your 3D Solid Model of a Ball.
Click on Front in the left column ... then the little arrow pointing Up and see you are now looking at the front of the ball.
Okay, now you know how to make solids ... next task is to cut using sketches and tools ... that's all there is to learning SolidWorks for 3D Modeling.
The hardest part is coming up with things to sketch for practice ... What I did to learn is take a walk outside ... whenever I see a little plastic or metal thing on the ground I pick it up, take it home, measure and sketch the object in SolidWorks until I've essentially become a SolidWorksMagi.
Just think of it as clay ... you add and subtract clay until you get the shape you want.
Step 11: Back to the Contest ...
Step 12: WrapUp ...
By the time the child is in high school they have a strong S.T.E.M. foundation and can move forward in programming classes, digital electronics classes ... by college they're well ahead of the kids that never got to play with a BallBot1 robot.
I just want to get it into production now so I can prototype more and more of the different robot designs I've been working on ...
