Robot Weight Budget
A running total of your robot's weight by subsystem, from parts you weighed, against a target you set. Parts you haven't weighed are counted, never guessed.
Inputs
Your team’s own target. Leave at 0 for no target.
Results
Robot weight, from the parts weighed

By subsystem
Weight of each subsystem and its share of what has been weighed.
Set a weight target
What you have weighed so far, stacked subsystem by subsystem, against the target line you set. Each band is one subsystem, the biggest at the bottom. Parts you have listed but not weighed are the open band on top: the stack can only grow from here, so a target that looks close with parts still unweighed is not close yet.
How this is calculated
Each part’s weight is how many × weight each, and the subsystems add those up.
subsystem weight = Σ (how many × weight each) share = subsystem weight ÷ total weighedOunces and grams are changed to pounds by their definitions: 16 oz to a pound, 453.59237 g to a pound.
Make a notebook page
Turns this calculation into a dated engineering notebook page: the setup, data, results, figures, working and sources, numbered and cited. You add the goal, the decision and the reflection in your own words, plus photos and sketches. Print it, paste it into Google Docs, or download a Word file or slides.

Sources & assumptions
No VEX figures are used. Every weight is yours, typed or measured; the totals are derived from them.
