What happened
During a motion-synchronization test, the Unitree G1 humanoid robot was meant to replicate an engineer's movements smoothly but deviated while mimicking a kicking motion and struck the engineer in front of it.
The engineer fell into a squat from pain, and the robot simultaneously mimicked the squatting posture.
Reported impact
The engineer was struck and experienced pain sufficient to cause them to squat down immediately.
Index analysis
The robot was operating in a teleoperator mode where it synchronized with human movements in real time.
The motion deviation occurred during the kicking segment of the synchronized movement demonstration.
