1. A stroker device for use in a borehole located in the ground, said stroker device comprising:
an actuator having a actuator being arranged to displace a tool in a longitudinal direction of the borehole; a gripper module with grippers being forced to a wall of the borehole or pipe wall to prevent displacement of the stroker device; a propulsive module having a first and a second set of driving wheels being mutually rotated approximately 90 degrees about the longitudinal axis of the stroker device for driving the stroker device to an operation location; a hydraulic module for commonly supplying hydraulic pressure fluid to the actuator, the grippers and the propulsive module; a control module for commonly controlling at least the grippers and the propulsive module simultaneously; and a power module for commonly supplying power to at least the grippers and the propulsive module.
