In the context of computer science, what does robotics involve?

Robotics encompasses the construction and operation of robots, which are programmable machines capable of carrying out a series of actions autonomously or semi-autonomously. This field integrates various aspects of engineering, computer science, and technology to develop systems that can perform tasks ranging from simple repetitive actions to complex decision-making in unpredictable environments. Robotics involves not only building the physical component of robots but also programming them to perform specific tasks through sensors and algorithms, which reflects the core principles of computer science in terms of automation, processing, and control.

Other choices focus on different aspects of technology. Designing mobile applications pertains to software development without any direct connection to physical machines. Data encryption techniques are concerned with securing information, rather than the mechanics of robots. Networking computers for data sharing involves connecting systems for communication and data transfer, distinct from the physical and operational concept of robotics. Thus, the correct answer emphasizes the integral role of construction and operation in the field of robotics within computer science.
