What's New & Improved

Enhanced UCMovementButtons for Single Speed Scenarios

We’ve expanded the functionality by creating a new UCMovementButtons user control to support movement panels. This enhancement is especially useful for skills like Auto Position, where 4 K displays and scaling cause issues with rendered UI components.

Why it matters: Some users on 4K monitors reported hidden buttons caused by poor Windows DPI scaling. The updated control now ensures buttons remain visible and properly scaled regardless of resolution or monitor size.


New Reusable UserControl for Movement Panels

Introducing a brand-new user control designed explicitly for movement buttons or movement panels. This control is modular and docks seamlessly inside any container, scaling with robot skill layouts while keeping your UI sharp and functional.

This control can now be reused across all new robot skills involving movement, making development more consistent and future-proof.


UI Thread Optimization

We’ve consolidated multiple UI-invoked methods into a single batched action. This reduces CPU overhead and improves UI responsiveness when updating movement controls or other related visuals.

You’ll notice a smoother and more efficient interface when issuing movement commands or interacting with skills that refresh the UI frequently.


Under the Hood

  • Improved visual scaling for Auto Position and similar skills on high-resolution displays
  • Consolidated UI thread invocations for optimized performance
  • Laid groundwork for consistent and modular UI components in future Robot Skills

Stay tuned for more updates-and keep on building awesome robots!
