Description: A large number of robots have been developed, and researchers continue to design
new robots with greater capabilities to perform more challenging and comprehensive
tasks. Between the 60s and end of 80s, most robot applications were related to
industries and manufacturing, such as sembly, welding, painting, material handling,
packaging, etc. However, the state-of-the-art in micro-technology, microprocessors,
sensor technology, smart materials, signal processing and computing
technologies, information and communication technologies, navigation technology,
and the biological inspiration in developing learning and decision-making
paradigms, MEMs, etc. have raised the demand for innovative solutions targeting
new areas of potential applications.-A large number of robots have been developed, and researchers continue to design

Description: 东西、南北两干道交于一个十字路口，各干道有一组红、黄、绿三色的指示灯，指挥车辆和行人安全通行。红灯亮禁止通行，绿灯亮允许通行。黄灯亮提示人们注意红、绿灯的状态即将切换，且黄灯燃亮时间为东西、南北两干道的公共停车时间。设东西道比南北道的车流量大，指示灯燃亮的方案如表。
60S 5S 80S 5S ……
东西道 红灯亮 黄灯亮 绿灯亮 黄灯亮 ……
南北道 绿灯亮 黄灯亮 红灯亮 黄灯亮 ……
表说明：
（1）当东西方向为红灯，此道车辆禁止通行，东西道行人可通过；南北道为绿灯，此道车辆通过，行人禁止通行。时间为60秒。
（2）黄灯闪烁5秒，警示车辆和行人红、绿灯的状态即将切换。
（3）当东西方向为绿灯，此道车辆通行；南北方向为红灯，南北道车辆禁止通过，行人通行。时间为80秒。 东西方向车流大 通行时间长。
（4）这样如上表的时间和红、绿、黄出现的顺序依次出现这样行人和车辆就能安全畅通的通行。
（5）此表可根据车流量动态设定红绿灯初始值。-East and West, North and South two roads intersect at a crossroads, the roads have a set of red, yellow and green indicator light, command vehicles and pedestrians safe passage. Red light is prohibited to pass, the green light to allow passage. The yellow light prompts attention to the red and green light will switch the state, and the yellow light time brighten things north and south corridors in the public parking time. North-South Road, East Road, located in the traffic flow than the large, light brighten the program, such as tables.
