1.2. Glossary of Robotics TermsΒΆ

Actuators cause the effectors to perform action. (motors, relay switches, pneumatic solenoids ... )
Autonomy is the ability to make decisions independent of human control and act on them.
The brains of the robot that uses information from sensors and human users to control the actuators.
Control System Theory
Control Sytems deal with dynamic systems. These are abstractions that describe something that changes over time. Control System Theory deals with how we can influence this change of the system.
Differential Drive
Two drive wheels on either side of the robot. Other wheels are used to provide balance, but movement and steering is controlled by setting the velocities of the two drive wheels.
Effectors enable a robot to take action. (wheels, arms, grabbers, wings, ...)
Kinematics is the branch of classical mechanics which describes the motion of points, bodies (objects) and systems of bodies (groups of objects) without consideration of the causes of motion.
A robot is an autonomous system which exists in the physical world, can sense its environment, and can act on it to achieve some goals. The term Robot is actually a Czech word meaning worker or slave. It was coined in a 1920 play, by the Czech playwright Karel Capek, entitled Rossum’s Universal Robot or RUR.
Sensors detect information about the robot’s environment.
