Özet, BOM ve kaynaklar
Overview
ToddlerBot was developed at Stanford by Haochen Shi, C. Karen Liu, Shuran Song and colleagues as a low-cost, easy-to-repair ML platform — a broken part can be reprinted the same day.
Version 2.0 (August 2025) comes in a default 2XC build and a stronger 2XM build. The team publishes an assembly manual, PCB files, RL training and diffusion-policy code.

3D printing & fabrication
- Materials: 2 kg Bambu PLA-CF (carbon-fibre PLA) + 1 kg PLA Basic.
- The team prints on a Bambu X1-Carbon, about 10 hours per plate; orientation and settings matter for strength.
- Official plates (19 each for 2XC / 2XM) are on MakerWorld (sign-in required); parts can also be exported from Onshape.
Official MakerWorld plate list (19 each for 2XC / 2XM, 38 in total)
