A

From service robots in virtual stands to 5 G applications displayed in cloud booths (展台),several innovations stood out at the 2020 China International Fair for Trade in Services CIFTIS),which was held from Sept 4 to 9 in Beijing.Themed "Global Services,Shared Prosperity"the event has presented many cutting-edge technologies.Let's take a look.
AI-powered garbage-sorting robot
It can detect and sort the garbage on the conveyor belt and then throw it into different dustbins.For example,it will put plastic bottles and containers into recyclable dustbins.With advanced technologies such as cloud computing and robot automation,the robot can sort through garbage with an accuracy of 98 percent,which will significantly reduce operating costs and improve efficiency.
Bionic
(仿生的)machine shark
A dark gray,life-size "shark"
was also displayed at CIFTIS.This bionic shark can move forward by imitating the swinging motion of fish tails.It has a maximum speed of six knots about 11 kilometers per hour),which is much faster than the average speed of about two knots of other bionic submersible (潜水的)vehicles.It is equipped with lighting,a camera system and imaging sonar (声呐),which can be used for underwater searches,seafloor mapping and underwater shooting.
Driver fatigue
(疲劳)warning system
A warning system to prevent people from falling asleep while driving was introduced at the fair.It can judge whether the driver is sleepy by monitoring how long the driver's eyes close or if his or her head drops.If the driver enters a state of fatigue,the system will immediately sound an alarm until the driver's eyes reopen and he or she starts to blink at a normal frequency.In the future,other dangerous driving behaviors,such as not wearing a seat belt and making phone calls while driving,might also be added into this warning system.
