Title:
DRIVING UNIT AND DRIVING METHOD OF THE SAME
Document Type and Number:
Japanese Patent JP2015223418
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To detect a state of movement of a section to be mounted being mounted with a driving unit and to assist operation of the section to be mounted.SOLUTION: A driving unit comprises: a mounting mechanism mounted to a section to be mounted; an actuator driving the mounting mechanism; and a first force sensor and a second force sensor being provided to the mounting mechanism and detecting force. The first force sensor and the second force sensor are provided at positions where a first detection value obtained from the first force sensor and a second detection value obtained from the second force sensor vary in response to movement of the section to be mounted. The actuator drives the mounting mechanism such that the second detection value is brought into a constant state in the case where a difference between the first detection value and the second detection value is less than a first threshold value set beforehand and the first detection value or the second detection value is greater than a second threshold value set beforehand.
