From Prototype to First Serve

From Prototype to First Serve

EVT-2 Baseline Completed

In January, Mavio completed the baseline validation of the EVT-2 prototype.

The goal at this stage was not to showcase complex features. Instead, we focused on confirming whether Mavio had the core foundation for real training tests: connecting through the app, confirming device status, running basic controls, and delivering stable ball feeds.


This Month’s Focus

EVT-2 was our baseline engineering validation stage.

We focused on three core questions:

Can the app connect clearly?

Can the machine feed reliably?

What real issues appear during repeated use?


Key Progress

  • EVT-2 prototype baseline validation completed Core feeding ability, continuous operation, and basic machine stability were validated in the first test phase.

  • Basic app connection flow completed The app can search for nearby Mavio devices, connect to the machine, and show basic connection status.

  • Basic feeding control validated Start, pause, and stop controls were implemented in the first interaction flow, allowing the machine response to be checked before training. This also marked a small but exciting milestone: we began practicing with our own ball machine!

  • Top ball speed confirmed to be higher than all competitor machines we could find The prototype confirmed its ability to support high-speed feeding tests.

  • Key issues were identified Testing revealed ball-feeding jams, unstable entry at extreme angles, and high-speed serving wheel stability risks. These findings were carried into the next prototype iteration.


What We Learned

EVT-2 confirmed that Mavio is not just about “being able to feed a ball.” It needs to stay stable during repeated training.

Top speed is only one part of the product. Direction stability, rhythm, feeding path, and long-run reliability matter just as much.


What’s Next

The next stage will focus on feeding stability, jam reduction, ball-path consistency, and high-speed mechanical reliability, moving Mavio from “baseline functional” toward “ready for continuous training tests.
