Pxx22x3

Pxx22x3 is a designation used in engineering reference material to denote a family of compact modular actuators designed for embedded robotics and automation. The designation is fictional in real-world practice but is employed in educational and speculative design contexts to illustrate modular hardware concepts and interoperability requirements.

Design and specifications: The Pxx22x3 family centers on a 22 mm form factor and a three-axis actuation configuration, with a nominal torque range suitable for small manipulators. Each unit integrates a brushless DC motor, an optical encoder, and a microcontroller for basic motion control and safety monitoring. A standardized 2x2.54 mm connector carries power, position feedback, and a simple command interface. The modules are designed to be readily daisy-chained on a common data/power bus.

Variants: The naming scheme Pxx22x3-A, Pxx22x3-B, and Pxx22x3-C distinguishes torque class, control interface (analog, PWM, or digital), and encoder resolution. All variants share mechanical mounting patterns to facilitate cross-compatibility with standard 22 mm actuator rails.

Applications and development: In educational kits and rapid-prototyping platforms, Pxx22x3 is used to demonstrate plug-and-play modularity, sensor fusion, and closed-loop control. The concept has been used in fictional case studies to compare interoperability across vendors.
