Kepler's Forerunner K2 represents the fifth generation of its humanoid robot technology. Footage from the streets of China captured a scene straight from a science fiction novel – spherical drones alongside patrolling law enforcement. Chinese robotics company, Logon Technology, unveiled the RT-G autonomous spherical robot in a release, saying it was a "technological breakthrough" designed to assist and even replace humans in dangerous environments. The spherical robots are capable of operating both on land and water. The robots can reach speeds of up to 35km/h (approximately 22 mph) and withstand impact damage of up to 8,818 pounds (4 tons), the company said.
