The ability to turn cockroaches into dead hard creatures

Cockroaches are considered one of the most deadly creatures on the planet thanks to special stamina in extreme conditions.

Cockroaches are very difficult to destroy.

1. You cannot block them : Cockroaches can slip through a gap of 1/4 of their body height in less than 1 second.
2. You cannot catch them : cockroaches can run at speeds of 50 times the body length per second, corresponding to a speed of 322km / h in humans. Only the smallest spaces can reduce their speed.
3. You cannot crush them : Cockroaches can withstand forces greater than 900 times their body weight without being injured.

These characteristics can suggest design of distress search robots to quickly locate survivors in narrow spaces.
