Robotics Industry Glossary
C
CAD (Computer-Aided Design)
Software used to design and model robot structures, mechanisms, and components in 3D before manufacturing.
Calibration
The process of adjusting a robot’s kinematic model and sensor readings to match real-world measurements, improving accuracy.
Camera Calibration
The process of determining a camera’s intrinsic (focal length, distortion) and extrinsic (position, orientation) parameters for vision-based robotics.
CAN Bus (Controller Area Network)
A robust communication protocol widely used in industrial robots, mobile robots, and automotive systems for connecting actuators and sensors.
Capex (Capital Expenditure)
Funds spent by a company to acquire or upgrade physical assets like robots.
Cartesian / Gantry Robot
Moves along three orthogonal linear axes (X, Y, Z), ideal for large-volume 3D printing, CNC routing, and material handling.
CE Marking
A certification mark indicating conformity with health, safety, and environmental protection standards for products sold in the EU.
Cell
A work area containing a robot, its controller, and any safety devices and equipment needed for a specific task.
Center of Gravity (CoG)
The point where a robot’s total mass is effectively concentrated; critical for stability in walking and mobile robots.
Chassis
The structural frame or body of a mobile robot that supports all components, including motors, sensors, and electronics.
Choreography (Robot)
The programming and design of coordinated robot movements for performance, entertainment, or demonstration purposes.
Classical Control
Control theory based on transfer functions, frequency response, and Laplace transforms, including PID and lead-lag controllers.
Closed-Loop Control
A control system that uses feedback from sensors to continuously adjust the robot’s actions to achieve a desired state.
Cloud Robotics
Offloading heavy computation, data storage, and collective learning to centralized cloud servers, enabling fleet-wide knowledge sharing.
Cobot (Collaborative Robot)
A robot designed to work safely alongside humans in shared workspaces, equipped with force sensing, rounded designs, and speed limitation.
Collaborative Robot (Cobot)
Designed to safely share workspace with humans, featuring force limiting, rounded edges, and advanced collision detection.
Collision Avoidance
Algorithms and sensor systems that prevent a robot from colliding with obstacles during navigation or manipulation.
Collision Detection
The capability of a robot to sense and respond to unintended contact with objects or people, either through force/torque sensors or software models.
Compliance
The ability of a robot or joint to yield slightly under external force. Can be passive (mechanical) or active (control-based).
Compliant Mechanism
A mechanical structure that achieves motion through elastic deformation of flexible elements rather than traditional joints.
Computer Vision
The field of enabling computers to interpret and understand visual data from images or videos.
Configuration
A specific set of joint positions (angles or displacements) that defines the pose of a robot at any moment.
Configuration Space (C-Space)
The abstract space of all possible robot configurations, used for planning and collision avoidance algorithms.
Control Loop
The continuous process of reading sensor data, computing control actions, and sending commands.
Conveyor Tracking
A capability allowing a robot to pick or place objects on a moving conveyor belt by synchronizing its motion with the belt’s speed.
Cooperative Robotics
Multiple robots working together on a shared task, requiring coordination, communication, and distributed planning.
Coulomb Friction
A type of friction that opposes motion with a constant force regardless of speed, common in robot joints and gears.
Coverage Path Planning
Algorithms that generate paths ensuring a robot’s sensor or tool covers an entire area, used in cleaning, mowing, and inspection.
Crawler Robot
A tracked mobile robot designed for rough terrain, stairs, and outdoor environments, offering high traction and stability.
CT (Computed Tomography)
Imaging technology used in industrial robotics for non-destructive inspection of internal structures of manufactured parts.
Cyber-Physical System (CPS)
An integrated system combining computation, networking, and physical processes; foundational concept for Industry 4.0 and smart robots.
Cybernetics
The science of control and communication in animals and machines, foundational to robotics.
Cyborg
A being with both organic and biomechatronic body parts; the intersection of robotics and bioengineering.
Cycle Time
The total time taken for a robot to complete one full operation and return to start position.
