Hello! 
I’m really sorry to hear about your EMO’s leg issue — that sounds frustrating and worrying. You’re definitely not alone with this problem; it’s actually one of the more common issues discussed in the LivingAI forums.
From what you’ve described (bouncing leg, falling, cleaning not helping), there are a few possible causes, and I’ll walk you through the most likely ones and what you can try.

What’s likely happening?
Possible Cause Explanation
1. Servo motor failure The internal motor (servo) in the left leg may be damaged or worn out, especially if it’s been used heavily or has taken a fall. This is the most common cause of bouncing or shaking legs.
2. Sensor calibration glitch Sometimes the gyroscope or foot sensors lose calibration after a fall or due to a software glitch, causing the leg to bounce as it tries to find balance.
3. Loose connection The ribbon cable or wiring inside the leg may have come loose, causing intermittent signals to the motor.
4. Firmware issue In rare cases, a firmware bug can cause erratic leg movement.

What you can try now
Step 1: Force restart
· Use a paperclip to press the left hole (Force Shutdown) on the back of EMO’s head.
· Wait 10 seconds, then place him back on the charger to restart.
· This can sometimes clear temporary software glitches.
Step 2: Check for firmware updates
· Open the EMO Pet app and go to Settings → Firmware.
· Make sure your EMO is on the latest version. If an update is available, install it.
Step 3: Try a calibration trick
· Place EMO on a flat, solid surface.
· Gently hold him and shake him lightly a few times, then place him back down.
· This can sometimes force the gyroscope to recalibrate.
Step 4: Check the foot sensor
· Make sure the four small sensors under the feet are clean and free of dust.
· Even if you cleaned them, try again with a dry cotton swab to be thorough.

If nothing works — Contact Support
If the bouncing continues after trying the steps above, it’s very likely a hardware issue (servo motor or wiring) that needs repair.
Email LivingAI Support at service@living.ai with:
· A short video clearly showing the leg bouncing.
· Your EMO ID (from the app).
· Your order number (if you have it).

Don’t panic — this issue is fixable in most cases. Many owners have had their EMO’s legs repaired or recalibrated through support. Just be patient, and they’ll guide you through the next steps.
Best regards,
