Rookie Prototyping Materials
What suggestions are there for materials to have on hand for prototyping the first week of build season? This is my first year involved with a team that doesn't have a large stock pile of materials and parts from previous seasons.
Some things that I've come up with: Plywood and lexan Aluminum sheet, angle, and box tubing Nuts and bolts of various sizes 80/20 (Good for structural standoffs) Surgical Tubing Wheels of various sizes and hubs Motors from 2015 What else are we missing? Anything on this list that you don't think we really need? |

I've always liked pvc piping and 2x4's.
Usually, we need lumber/wood screws to build goals and other field components as well. Something to drive motorized prototypes, such as an old drill handle or a servo driver. |

A hand drill, something to make 1-1/8 holes (hole saw?), bearings, hex shaft, wheels with hex bore, and you can have something rolling really quickly.:D

If by various sizes you mean lengths, then yeah that is fine. We mostly commonly use 1.5" for bolting panels to 1" extrusion, 2.5" for bolting two extrusions together, and .75" for bolting two or three panels together |

We have standardized our team to using 1/4 20 nuts and bolts and 3/16 rivets.
Also add flat stock to your list it's very useful. |

1/2" hex shaft and a 1/2" nut driver for spinning things with a drill.

Get this darn thing - 1.125" Step Bit
I wish we would have had it when we first started. |

Re: Rookie Prototyping Materials
Check out the Prototyping workshop we gave a couple years ago. There are some others that are helpful also.

Re: Rookie Prototyping Materials
Don't forget the prized prototyping material; the pizza box + duct tape.
We've used the cardboard lid of a pizza box to initially prototype a variety of items (both on the robot and for the playing field) because they're handy (accessible) and cheap (re-using)! Good luck! |
