EVT-4 Sampling and Volosophy Beta App Begins

In May, Volos entered the EVT-4 prototype stage.

May had two major priorities:

First, the hardware entered EVT-4 and began preparing for stricter long-term reliability testing.

Second, the Volosophy Beta App began with Highlight clipping, while the Volosophy AI Coach demo app completed its first validation and will be released gradually together with the Volos hardware training experience.


Key Progress

  • EVT-4 design files completed The prototype entered factory sampling, with a focus on long-term stability, durability, and manufacturability.

  • Serving wheel prototype completed The serving wheel prototype entered continuous operation testing to observe high-speed stability and wear performance.

  • Custom circuit board and control box plans confirmed The circuit board and control box design plans were confirmed to support more stable machine control in later system validation.

  • Formal test site completed Long-term reliability tests can now be conducted in a more stable environment closer to real training conditions.

  • Volos lifespan test plan confirmed.
    The goal is to validate reliability over more than 1,000,000 continuous feeds.


  • Volosophy Beta App launched with Highlight clipping.
    Highlight clipping is the first lightweight public Beta feature, allowing early users to experience Volosophy’s intelligent video understanding.


  • Volosophy AI Coach demo app completed first validation.
    The demo can generate feedback, summaries, and next-step practice suggestions based on training performance.


  • Volosophy AI Coach and Volos training flow completed first integration validation.
    Training analysis can connect to follow-up practice content, but the full experience will be released gradually together with the Volos ball machine Beta.


What We Learned

The value of Volosophy AI Coach should not stop at “telling you what went wrong.”

The real value is turning analysis into the next training action. That is why Volosophy AI Coach will not be released early as a fully standalone feature. Its complete experience needs to appear together with the Volos ball machine: analyze training, identify the issue, and turn that issue into the next executable drill.


What’s Next

EVT-4 will move into stricter full-machine validation for Volos, including serving wheel aging, long-run operation, direction detection, heat, stalling, interruptions, and continuous feeding lifespan tests.

On the Volosophy app side, we will continue validating the Highlight feature and the AI Coach demo experience.

Highlight is the first public Beta feature. Volosophy AI Coach is already demo-ready and will be released gradually with the Volos hardware training experience.
