Every part in the catalog is a component, not a certified finished product. You are building the robot; that means the safety decisions, actuator torque limits, battery handling, enclosure choices, are yours too. Here is what we'd want to know if we were building one ourselves.
Before you power anything on
- Torque and pinch points: any joint strong enough to lift its own limb is strong enough to injure a finger. Keep hands clear during first power-on and testing, and add software torque/current limits before mechanical testing near people.
- Battery handling: lithium packs need a real battery management system, a fused disconnect, and a fire-safe storage/charging area. Never leave a charging pack unattended.
- E-stop: build in a physical, no-questions-asked power cutoff before you test any multi-joint assembly under load.
- Enclosure: sharp printed edges and exposed gear trains are normal on a prototype, treat an unfinished build as shop equipment, not a toy, especially around kids or pets.
Standards worth knowing about (not certifications we hold)
If you're moving from a hobby build toward something you'd sell or place in a home unsupervised, the relevant frameworks to research are UL 3300-series and ISO 13482 (personal care robot safety), and your battery pack's UN 38.3 shipping documentation if you plan to ship built units. We are not certified to any of these today, this is a pointer to where to start looking, not a claim of compliance.
