The Survey Runner made by Topy of Tokyo is designed to help out after a nuclear accident. The 88-pound (40-kilogram) robot can climb up stairs or over rubble, and carries two wide-angle cameras and a radiation sensor.

If the robot needs to work inside heavily shielded nuclear facilities, it may not be able to communicate using radio. If that’s the case, a thin, tough, fiber-optic cable that trails from a reel lets the robot’s operators stay in touch.
