Safety and Certification
What we design to, what we test against, and where each product stands. Status lines change only when a test completes or a certificate is issued.
Principles
- Every physical command has a dead-man switch and a latency budget.
- One human gives the final approval for any consequential action, and every action is logged.
- Hardware carries dual e-stop, safety-rated speed and separation, and protective stop. B1 adds controlled fall.
- Vendor telemetry is removed. Only our own communications stack runs on the machine.
