Introduction

Medical robotics is the use of robots to assist in healthcare tasks, ranging from surgery and diagnostics to rehabilitation and patient care. Robotics in medicine combines engineering, computer science, and medical expertise to improve patient outcomes, enhance precision, and increase efficiency.

Key Concepts

What is a Medical Robot?

  • Definition: A programmable machine designed to perform medical tasks with high precision.
  • Types: Surgical robots, rehabilitation robots, diagnostic robots, telepresence robots.

How Do Medical Robots Work?

  • Sensors: Gather data about the patient or environment.
  • Actuators: Perform movements or actions based on commands.
  • Software: Controls robot behavior, often using AI for decision-making.
  • Interfaces: Allow doctors to control or monitor the robot.
