Explanation: 

Detailed explanation-1: -Another way this might be beneficial is during a robotic precursor mission. R2 would bring one set of tools for the precursor mission, such as setup and geologic investigation. Not only does this improve efficiency in the types of tools, but also removes the need for specialized robotic connectors.

Detailed explanation-2: -What is the author implying by the allusion to Armstrong’s statement in paragraph 3? Like Armstrong’s Moon landing, the launch of the first Robonaut aboard the Discovery represents a historic breakthrough in space exploration.

Detailed explanation-3: -Robonaut is a NASA robot. Engineers designed Robonaut to be humanoid, which means it is built to look like a person. This makes it easier for Robonaut to do the same jobs as a person.

Detailed explanation-4: -Robonaut has a head, torso, arms and hands like a person. Cameras in the head provide vision. Robonaut is called a dexterous robot because its hands and fingers move like a person’s. So Robonaut can perform tasks designed to be done by human hands.
