A team of researchers set up an e 1 They wanted to find out how a robot best learns to do a certain task. They also hoped to learn how a robot can best explain its actions to w 2 humans’ trust. The engineers built a robot. Then they gave it a task. It had to open a safety-locked medicine bottle. First, a person showed the robot how to do it. The person wore a special glove that measured his hand positions and the forces he used to open the bottle. E 3 time the person's hand moved, an action word described it. For example, words like“push” or“twist” were used. This was symbolic information. The robot needed this information to know how to open the bottle. Then researchers gave the robot the bottle. But it h 4 ever got the bottle open. Why did it fail? The robot had the symbolic information it needed. But it didn't have the haptic (触觉的)information. The researchers left that out. What's haptic information? It has to do with what you feel when your body moves. For example, humans don't just grasp and twist safety-locked bottles. We squeeze the cap tightly. We feel when the cap jams. Then we change our force until we l 5 the cap. The robot tried again. This time it had symbolic and haptic information. Success! The robot opened the bottle.

Which group trusted the robot the most? The group that r 7 both the symbolic and haptic information. And they said the symbolic information helped them see the robot as trustworthy.
