Abstract
An activation system of a work machine includes a vehicle body control unit outputting a control signal to drive a vehicle body of the work machine with power supplied by a power source, and an authentication unit performing authentication of an operator of the work machine. The activation system of a work machine first activates the authentication unit, and activates the vehicle body control unit when the authentication unit authenticates that the operator boarding the work machine is a specific operator.
