The field combining mechanical engineering, electronics, and software to create machines that can perform tasks autonomously or semi-autonomously.
Robotics combines hardware and software to create machines that sense their environment, make decisions, and perform physical actions. Robots automate tasks that are dangerous, repetitive, or require precision beyond human capability.
Sensors: Cameras, proximity sensors, gyroscopes, accelerometers. Robots perceive their environment through sensors.
Actuators: Motors, servos, pneumatics. These create movement and physical actions.
Controller: The brain - microcontrollers or computers running software that processes sensor data and controls actuators.
Power Supply: Batteries or external power. Robots need energy to operate.
Software: Algorithms for perception, decision-making, and control. This is where developers contribute to robotics.
Industrial Robots: Assembly line arms, welding robots, packaging machines. Highly precise, repetitive tasks.
Service Robots: Vacuum cleaners (Roomba), delivery robots, warehouse robots (Amazon fulfillment centers).
Medical Robots: Surgical robots (Da Vinci system), rehabilitation robots, pharmacy automation.
Autonomous Vehicles: Self-driving cars, delivery drones, agricultural robots.
Humanoid Robots: Research platforms and assistants attempting human-like interaction.
No related topics found.
Perception: Computer vision to identify objects, LIDAR for mapping environments.
Planning: Algorithms to determine actions - path planning, task scheduling.
Control: Low-level code controlling motors and actuators precisely.
Machine Learning: Training robots to improve through experience.
Simulation: Testing robot behavior in virtual environments before real deployment.
ROS (Robot Operating System): Framework for building robot software. Industry standard.
Python: Common for prototyping and AI components in robotics.
C++: Used for real-time control systems requiring performance.

Computer Vision: Neural networks identify objects, people, and obstacles.
Reinforcement Learning: Robots learn optimal strategies through trial and error.
Natural Language Processing: Enables voice interaction with robots.
AI makes robots more adaptable and capable of handling varied situations.
Job Displacement: Automation replaces human workers. Society must address this transition.
Safety: Robots working near humans must not cause injury. Extensive testing and safety protocols required.
Autonomous Weapons: Military robots raise ethical concerns about automated killing.
Privacy: Robots with cameras and sensors collect data about people and environments.
These concerns require thoughtful regulation and ethical frameworks.
Hobbyist Kits: Arduino robot kits, LEGO Mindstorms for learning basics.
Simulation: Gazebo, Webots for testing robots virtually before building hardware.
ROS Tutorials: Learn industry-standard framework for robot development.
