Abstract
A micro-manipulator has grippers for gripping micro-material; an actuator for driving the grippers; a drive amount detection device for detecting a drive amount of the actuator; a power control device for controlling power supplied to the actuator so that a difference in a target drive amount of the input actuator and a drive amount detected by the drive amount detection device is small, after at least the grippers touch the micro-material; a gripping determination device for determining that grippers have gripped the micro-material based on the difference; and a resilience value calculation device for calculating a resilience value that represents a degree of softness of the micro-material by dividing the actuator drive force that is equivalent to the repulsive force of micro-material gripped by the grippers in proportion to power supplied to the actuator via the power control device.
