According to Ars Technica, Agility's new humanoid robot is designed to stop and squat when it needs to avoid harming human coworkers. The report frames this as a shift away from protecting people with physical cages and safety barriers, toward relying on the robot's own behavior in shared spaces.
The robot can therefore start working outside cages and without barriers, according to the report. That means the safety case is built into the machine's movements rather than into the surrounding environment.
Since there is only one source, there are no differing accounts to compare. The report does not describe additional safety systems or the limits of the stop-and-squat approach, so the available information is limited to the behavior itself and the claim about working without barriers.
