Robotics & Artificial Intelligence
Answer
The four types of controllers that can be used in robots are:
Microcontrollers — A microcontroller is a tiny computer embedded on a single chip. It consumes very low power and is used to control the functions of a robot.
Programmable Logic Controllers (PLCs) — PLCs are the programmable controllers that are specifically designed to work in industrial environment. The main purpose of PLCs is automating manufacturing process.
Digital Signal Processors (DSPs) — A DSP controller in robotics processes sensor data to control robotic components with precision, enhancing their responsiveness and accuracy. The DSPs may be used to process image, audio and video data.
Microprocessor — It processes information and helps the robot take decisions and perform tasks.
