Industrial Robot
A freely programmable, program-controlled handling device derived from the Slavic word robota, meaning hard work.
Robot System Components
The five fundamental components of a robot system: manipulator, means for programming, controller, end effector, and power supply.

Servo (Closed-Loop) Control
A control system that uses a feedback signal to detect and correct errors, allowing precise control of position or velocity.
Non-Servo (Open-Loop) Control
A control system with no feedback signal, typical of limited sequence or pick and place robots.
Electric Actuator Drive
An actuator drive mechanism using electric motors, such as Alternating Current (AC) Servo Motors, Direct Current (DC) Servo Motors, or Stepper Motors.
Hydraulic Actuator Drive
A fluid power system using oil with hydraulic cylinders and motors.
Pneumatic Actuator Drive
A fluid power system using compressed air with pneumatic cylinders and motors.
Work Envelope
The generated 3D volume of space reachable by a robot, determined by coordinate system, joint arrangement, manipulator segment lengths, and wrist reach.
Mechanical Joints
Structural connections between manipulator components, including Revolute, Prismatic, Cylindrical, Screw, Cardan, and Spherical joints.

Cartesian Work Envelope
A rectangular work envelope shape generated by linear Cartesian movements, available in Standard Configuration or Gantry Configuration.
Revolute Work Envelope
A work envelope shape generated by revolute arm joints that requires both a side view and a top view to properly present.
Degrees of Freedom (DOF)
The independent parameters describing a robot's freedom to move in 3-D space, where each degree of freedom requires a joint.

Robot Wrist
A section of the robot manipulator that increases end-of-arm tooling flexibility through three minor degrees of freedom.

Pitch
The minor degree of freedom representing the bend or up and down movement of the robot wrist.
Yaw
The minor degree of freedom representing the side to side movement of the robot wrist.
Roll
The minor degree of freedom representing the swivel or rotation of the robot wrist.
