Service robot malfunctions at Cupertino hotpot restaurant
A service robot at a HaiDiLao Hotpot restaurant in Cupertino, California malfunctioned while entertaining diners, spinning erratically and knocking over dishes. Although no injuries occurred, the incident demonstrates potential safety risks when robots operate in crowded spaces with hot food and beverages.
What happened
A service robot at HaiDiLao Hotpot in Cupertino, California experienced a malfunction while operating among dining tables. The robot began jerking, spinning rapidly, and knocking over plates, chopsticks, and food onto the floor.
Three restaurant staff members intervened to restrain the robot, which continued moving its arms for some time before being brought under control. A staff member appeared to use a smartphone, possibly to disable or control the system remotely.
Reported impact
No customers or staff were injured in the incident. Nearby diners were startled by the robot's sudden uncontrolled movements.
HaiDiLao stated that the robot was not out of control and had been brought close to a table at customer request in a confined space that restricted its movements.
Index analysis
The incident highlights potential risks when robots operate in crowded restaurant environments, particularly in establishments serving very hot liquids where an accidental collision could cause burns beyond property damage.
It is unclear whether the robot had an easily accessible emergency stop system or whether staff had been adequately trained to manage such malfunctions.
