What components enable a robot to run without human control?

• A. A remote control and video feed
• B. A microcontroller and autonomous programming
• C. Solar panels only
• D. A large battery pack

Answer: (B)

Autonomous operation comes from having on-board processing and software that can make decisions without human input. A microcontroller acts as the robot’s brain, running autonomous programming that uses sensor data to control actuators and decide what to do next. This combination lets the robot operate by itself, handling tasks like sensing obstacles, deciding a path, and moving motors without a person steering it.

Relying on a remote control and video feed means a human is directing the robot, so it isn’t autonomous. A power source alone—whether solar panels or a large battery pack—provides energy but doesn’t enable independent decision-making or control.
