velocitylevel

Velocitylevel is a term used in robotics, CNC, and automated systems to denote a parameter representing the target velocity for a subsystem. It is not a formal physical quantity; rather, it is an abstraction used by control software to bridge planning and actuation. The precise meaning of velocitylevel varies by system, and it may be represented as an integer level or a real-valued velocity.

In hierarchical control architectures, velocitylevel often maps to a velocity setpoint. The relationship is typically v_target = gain * velocitylevel or bounded by a maximum speed. A low-level motor controller then converts the setpoint into actuator commands, applying acceleration limits to ensure smooth motion and safety.

Examples: In a mobile robot, velocitylevel values might range from 0 to 10, with each step corresponding to 0.2 m/s; a velocitylevel of 5 yields 1.0 m/s. In a CNC spindle or gantry system, velocitylevel scales the feed rate toward a chosen target speed, subject to axis acceleration constraints.

Ambiguities: Because velocitylevel is an application-specific abstraction, different platforms use different scales and units. When integrating heterogeneous components, explicit documentation of the velocitylevel mapping is essential.

Related concepts include velocity control, speed setpoints, velocity profiling, and the broader distinction between position-level and velocity-level control.
