Which of the following statements best describes robotic arms?

The statement that robotic arms serve as tools for manipulation accurately captures their primary function in various industries. Robotic arms are engineered to perform tasks that involve precision and dexterity, making them essential in manufacturing, assembly, welding, painting, and even surgery. Their design allows them to handle materials, assemble parts, and execute repetitive tasks with high accuracy, thereby enhancing efficiency and productivity.

While robotic arms can indeed be found in entertainment or decorative contexts, this does not encompass their primary purpose. Furthermore, the assertion that they replace human workers completely is misleading; instead, robotic arms are often used to assist human workers, handling tasks that are hazardous, monotonous, or require a level of precision that may be challenging for humans to achieve consistently. Thus, emphasizing their role as tools for manipulation highlights their importance and versatility in practical applications across various fields.
