There are three main types of robots. An easy way to remember these types is the acronym MAG:

Manipulator (Robots that have arms to manipulate the world around them)

• Industrial robotic arms 
• Collaborative robotic arms

Aerial (Robots that fly)

• Fixed-wing unmanned aerial vehicles 
• Rotary-wing unmanned aerial vehicles

Ground (Robots that move using either wheels, legs, or tracks)

• Wheeled robots
• Legged robots
• Tracked robots

That’s the Market

These three types of robots account for 96% of all robots used commercially in the world today.

The other 4% are underwater robots … robots that swim.
