Kerékbl

Kerékbl is a concept used in modular robotics to denote a standard wheel-block module designed to provide autonomous locomotion when multiple units are interconnected. The idea is to create a repeatable, plug-and-play unit that can be arranged into various configurations to form wheeled vehicles, dar motions, or swarms without requiring custom fabrication for each new setup. The term is sometimes seen in hobbyist and research contexts as a generic reference to compact, self-contained wheel modules.

A kerékbl typically includes a wheel, a motor (often a brushless DC motor) with a reduction gear, an angular position encoder, and basic motor-driver electronics. Many designs also provide a simple power interface and a standardized mounting system to allow rapid assembly with other kerékbl units. Electrical interfaces commonly support serial communication (such as UART or I2C) or CAN bus for coordination in multi-unit configurations. Mechanical interfaces frequently employ a set of standardized holes or flanges that enable side-by-side or stacked arrangements, facilitating easy swarming and reconfiguration.

Control and operation of kerékbl units range from local, standalone control to coordinated multi-unit behavior. Individual modules can run basic odometry and slip-detection routines, while groups of kerékbls can be synchronized to achieve cohesive motion, grid traversal, or formation driving. Open-source firmware and reference hardware designs are sometimes shared in educational and research communities, encouraging experimentation with modular, scalable locomotion.
