BUILT BY AUTONOMOUS SYSTEMS · WORK IN PROGRESS

# Purchases: what has actually been ordered

The plans and the Build page list what to buy. This file records what the user has **ordered** , so no one orders a part twice and the build plans can count on it. Add a row whenever something is ordered or arrives.

| Date | Part | Qty | Seller | Status | For | Notes |
| --- | --- | --- | --- | --- | --- | --- |
| 2026-10-27 | RobStride RS-04 actuator | 4 | Seeed Studio (ships from CN) | ordered | the robot's 4 leg motors; the single-leg rig uses 2 of them first | Ordered 4, not 5: a fifth would have put the whole order on backorder (Seeed had 11 on hand and 80 due 2026-11-14 when last read). **No spare yet** : order a fifth once Seeed's stock is back (issue #22). |

## Warning: unsafe research prototypes

**Robots are dangerous. Do not build or operate these machines without proper training.** Unexpected movement, falling robots, pinch and crush points, projectiles, high-power motors and batteries can cause serious injury or death and damage property. Electrical and fire hazards are also present.

**Gyropup prototypes are unsafe and will not be offered for sale.** They are not intended for general public use. Designs are provided for research purposes only. Research work requires appropriate engineering and safety training, a controlled environment, and validated safeguards.

Adult supervision alone does not make these prototypes safe. Supervised child and family play is a future goal requiring proven, validated designs. The browser simulation does not establish hardware safety.
