What are the main components of robots?

Robots are made up of a series of components and they are:

  • Controller- This is the digital hardware and the software of the robot that allows it to perform assigned tasks.
  • Actuators- These are small motors fixed inside a robot that understands human gestures and performs tasks.
  • Electric motors- These assist in the robot's body's simple flow of energy. For robots to operate they turn the energy into workable energy.
  • Sensors- For a robot to operate proper signals and active sensors are needed. It also has a brain which is a chip that enables it to feel or understand signals.
  • Power Supply- A continuous power supply is needed for a robot to move about, or perform a task Many robots run by electricity while others function by batteries.
