Unitree R1: Battery charging faults / will not charge

R1 smart battery will not charge, overheats on charge attempt, or never reaches full (LEDs off).

R1 does not boot — pack may be unseated, empty, or failing the load/seat check.

Motion stops unexpectedly via external e-stop wiring, or stand/lie button timing confuses operators.

R1 vision (mono or binocular depending on variant) is degraded by dirt or covers on the camera module.

Suspended G1 powers on but does not finish initialisation (no ankle limit sound within ~2 minutes).

G1 falls during walk or cannot hold a stand after power-on; restart alone does not fix it.

Pack will not click into the G1, will not take a charge, or runtime collapses after sessions.

After a fall, motors enter braking/self-protection and the robot will not resume until cleared safely.

Perception degrades because camera lenses or the head-mounted LiDAR window are dirty or blocked.

Phone cannot connect to the G1 AP hotspot or Unitree app link drops in direct AP mode.

Humanoid will not take a charge, or runtime drops sharply after a normal session.

A limb joint reports a fault, stiffens, or makes grinding / clicking noise during motion.

Robot loses balance, falls, or fails fall-recovery on flat indoor floors.

Navigation or perception degrades because LiDAR or depth cameras are dirty, fogged, or covered.
