Robot Image Prompt Generator (Spreadsheet + Guide)
Create your own family of adorable or elegant robot characters to represent your GPTs.

Includes proven prompt formulas, color tips, and style tweaks for consistent, brandable visuals. These instantly make your GPTs look professional — and unforgettable.

HOW IT WORKS
The generator works in Google Sheets which anyone with a free Google account has access to. To use it, simply fill in a few fields and use smart dropdowns to design your perfect robot.

The dropdown selections come from the Input Data. We have added lots of suggestions for making great robot images but you can also add your own ideas if you wish.

Instantly get a structured, high-quality prompt to use in AI art tools like MidJourney, Nano Banana, and Sora.
Midjourney parameters included - no more trying to remember to enter “ - -” before each parameter or what each parameter means or the range of values! (If you don’t use Midjourney leave that section blank!)
