We introduce an innovative robotic device designed to enable controlled motion for the study of active matter. Motion is driven by an internal vibrator, powered by a compact rechargeable battery. The system integrates acoustic and magnetic sensors alongside a programmable microcontroller. Unlike conventional vibrobots, this device employs a motor that generates horizontal vibrations, producing cycloidal trajectories that have been thoroughly characterized and optimized. Specific segments of these trajectories can be harnessed to create tailored motion patterns. As a proof of concept, we demonstrate how this versatile system can be used to develop active particles exhibiting diverse dynamics, ranging from ballistic motion to run-and-tumble diffusive behavior. Based on experimental data, we provide a simulation routine capable of replicating these trajectories, enabling the generation of extended datasets and the exploration of various input velocity configurations. This approach facilitates the determination and prescription of optimized input parameters for applications such as enhanced search strategies and precise path following.
