Motorized roller skate

A motorized roller skate comprising two skate boards and a hand device, wherein each of the skate boards and the hand device respectively comprises a signal device and at least one sensor, and each of the skate boards and the hand device transmits a detection signal detected by the at least one sensor to a control center via the respective signal devices, wherein

• the detection signal comprises:
• a foot signal from one of the sensors on one of the skate boards or
• a hand signal from one of the sensors on the hand device;
• and
• a balance signal from one of the sensors on one of the skate boards and/or the hand device;
• and
• the control center is located on one of the skate boards or the hand device, and the control center stores one or more motion modes and one or more determination logics, each motion mode corresponding to one of the determination logics, wherein the control center receives the detection signals and, based on the current motion mode and determination logic, interprets the detection signals and generating a command to the signal device of at least one of the skate boards to accelerate, decelerate, maintain speed, or stop the skate boards according to the command;
• wherein, when the skate boards are in operation, the control center prioritizes execution of the determination logic associated with stopping operation of the skate boards.
