Mobile Robots“A mobile robot is an automatic machine that is
capable of locomotion.”
1. Unmanned Ground Vehicles (UGVs)
2. Delivery & Transportation robots3. Unmanned Aerial Vehicles (UAVs)
4. Unmanned underwater vehicles (AUVs)
Locomotion using:Wheels, Tracks, Legs, propellers, fins etc.

Aerial - Quadcopters“A quadcopter is a multirotor helicopter that is
lifted and propelled by four rotors”
● two sets of identical fixed pitched propellers;
two clockwise and two counter-clockwise● no torque induced control issues● small size and agile maneuverability
