Which of the methods below can be used to tell a robot what it is to do? A. Walk-through B. Set mechanical stops C. Software program D. (a) and (c) E. None of the above

The correct answer is D. (a) and (c).

A walk-through is a method of teaching a robot what to do by physically guiding it through the desired motions. This can be done by a human operator or by another robot. Set mechanical stops are physical barriers that prevent the robot from moving beyond a certain point. This can be used to prevent the robot from damaging itself or its surroundings. A software program is a set of instructions that tells the robot what to do. This can be written in a variety of programming languages.

Option A is correct because a walk-through is a method of teaching a robot what to do by physically guiding it through the desired motions. This can be done by a human operator or by another robot.

Option B is correct because set mechanical stops are physical barriers that prevent the robot from moving beyond a certain point. This can be used to prevent the robot from damaging itself or its surroundings.

Option C is correct because a software program is a set of instructions that tells the robot what to do. This can be written in a variety of programming languages.
