About
A board for people shopping a cheap arm
Robodex compares prices and stock for low-cost robot learning kits, starting with SO-101, SO-ARM101, and the LeRobot kits sold under those names. The same project shows up as a parts list, a motors-only box, a printed kit, and an assembled bundle with a camera. Those are kept in separate groups so the cheapest number is not treated as the same purchase.
Robodex is not a store, does not hold stock, and is not an official LeRobot, Hugging Face, or vendor site.
Prices are read from the shop pages. The comparison was first written down on October 16, 2026, and the latest check ran 16 Oct 2026, 11:18 UTC. When a shop page cannot be read, the row keeps the last price and is marked stale. Some shops do not allow an automatic check, so those prices stay at the last figure a person confirmed. Shipping and duties are extra unless a listing says otherwise. Check the shop before you pay.
A buy link leaves Robodex and opens the shop. The price on that page is the one that matters.
