Engineers in the US have created a group of robots. They are (1)
enough to work together to deal with obstacles (障碍) successfully.
"When ants collect or transport objects, if one meets an obstacle, the group will work (2)
to deal with that obstacle, "explained Dr Yasemin Ozkan-Aydin of the University of Notre Dame, who led the research. "If there's a break (缝隙)on the road, for example, they will create a (3)
. So the other ants can travel across and that is the (4)
for this study."
Ozkan-Aydin and (5)
partners 3 D printed a group of four-legged robots which are 15 to 20 centimeters long. They were fixed (6)
touch sensors (传感器)at the front and back, so that they could feel and connect to other robots in the group. The robots were then tasked with finding their way over different surfaces, (7)
grass, floors and carpets. Ozkan-Aydin also built stairs for them (8)
up using plastic or wooden blocks. Whenever a robot met difficulties, it would (9)
a signal (信号) to the other robots, before connecting together through their touch sensors.
Ozkan-Aydin hopes this (10)
could be used to make more robots to help in search and rescue operations (救援行动), transporting objects and space study in the future. However, in order to make that become a reality (现实), she says battery (电池) technology will need to improve so that the robots can ideally work for up to ten (11)
without running out of power.
