Mood plotter: a 246-part brick model designed with BricksChat

Mood plotter

Gather your own pieces or use the CSV’s part names, colours, quantities and Pick a Brick searches. IDs are LDraw part IDs, not LEGO element IDs. Check the colour and variant before ordering; some pieces may be unavailable or need a substitute. The CSV is a shopping list, not a cart import.

Paper Scout sweeper bot
Could you make me a little brick Roomba for paper scraps? It should avoid things and find its way back to a coloured home marker. I have one SPIKE Prime hub and up to 3 motors. Build it and write the code. Here’s a picture of how I want it to look.
