Hi there! I understand that when you're in Explorer mode on the Cozmo app and try to move his head, it switches to showing the lift (forklift) icon instead. That definitely sounds like the controls aren't responding as expected. To help fix this, can you tell me:

1. Are you using the latest version of the Cozmo app?
2. Have you tried restarting both the app and Cozmo himself since this started?
3. Is this behavior consistent every time you try to move his head, or does it happen intermittently?

In the meantime, here’s a step-by-step approach that usually resolves this kind of control mix-up:

1. Restart the app and Cozmo robot: Power Cozmo off and on, then close and reopen the app to refresh the connection.
2. Check the control mode toggle: Sometimes the app’s UI may be stuck on the forklift control instead of head movement. Look for a toggle or button in Explorer mode that lets you switch between controlling the head, treads, or lift. Make sure it’s set to head control.
3. Re-pair Cozmo with your device: Disconnect Cozmo from Bluetooth on your PC, then re-pair him fresh through the app settings. This can clear communication glitches.
4. Update firmware: Ensure Cozmo’s firmware is up to date by checking within the app’s settings or auto-update prompts. Firmware mismatches can cause weird behavior.
5. Inspect for physical issues: Gently move Cozmo's head manually to confirm that nothing is stuck or loose internally. Mechanical resistance can cause the controls to misbehave on the software side as well.

If after these steps the app still switches to the lift icon instead of moving the head when you hit that button, it could be a bug or UI glitch specific to the app version or your setup. At that point, I’d recommend reinstalling the app or reaching out directly to Digital Dream Labs support at [email protected] for more in-depth help.

Would you like me to guide you through any of these steps in detail? Also, let me know your answers to the initial questions so I can tailor the help better!
