Overview
Waltair Robotics is a mobile application built for tennis coaches to remotely control a smart ball-feeding machine, record training sessions, and analyze performance through real-time statistics and charts. The app connects via Wi-Fi, synchronizing machine commands, shot data (hand used, speed, direction), and live video streams enabling coaches to deliver data-driven training experiences. The project entered its final stage of active development. We focused on improving app stability, UI/UX consistency, and overall performance ahead of public release.
Challenge
Regressions in session timers, navigation flow, and video playback- Inconsistent UI behavior across iPhone, iPad, and Android (portrait & landscape)
- Synchronization issues with socket events and time tracking
- Monolithic code structure with large, hard-to-maintain components
- Unstable third-party libraries causing freezes and performance issues
- Lack of localization and limited data visualization
Solution
- Stability & Error Handling Improvements
- Resolved synchronization issues with socket events and refined session time-tracking logic.
- Fixed UI layout inconsistencies across iOS and Android devices.
- Improved error handling and validation within key user flows such as Account Settings and Custom Programs.
- Feature Enhancements
- Integrated new APIs to enable seamless communication between the mobile app and the tennis ball machine.
- Rebuilt the Play Clips view for smoother video playback and improved responsiveness.
- Implemented internationalization (i18n) and localization support for multiple languages.
- Enhanced Session Details and Live Statistics screens with dynamic chart updates and real-time data visualization.
- Improved navigation logic and UI transitions in “Change Other Params” and “Create Option Wizard” flows.
- Updated buttons, modals, and form components to align with the latest design guidelines.
- Refactoring & Optimization
- Decomposed large files into smaller, reusable components for better scalability.
- Replaced unreliable third-party libraries with stable, custom-built solutions to prevent navigation freezes.
- Migrated form validation logic to react-hook-form + Zod, reducing boilerplate and improving code readability.
- Communication & Collaboration
- Close collaboration with the client’s backend and product management teams to clarify requirements and align functionality with user expectations.
- Early regression reporting and proactive proposal of alternative solutions during sprint reviews.
Result
The updated Waltair Robotics Mobile App v4 now delivers a far more stable, intuitive, and scalable experience for tennis coaches.
