A biped robot walking in a crowd must avoid falls and collisions at the same time. The latter is usually addressed through Passive Safety (PS), which guarantees that the robot is at rest when a collision is inevitable. Since PS may limit the robot's mobility, the purpose of this work is to introduce and explore the novel concept of Time To Danger (TTD) as an alternative. For a given robot motion, ...
