Abstract
A robot control method includes gripping a work with a hand unit; transferring the work to the vicinity of a plane; dropping the work to the plane by reducing the grip force of the hand unit, and aligning the work with the plane; and re-gripping the work, which is aligned with the plane, again with the hand unit.
Claims15
A robot control method, comprising:
- gripping a work with a hand unit;
- transferring the work to a vicinity of a plane;
- dropping the work to the plane by reducing a grip force of the hand unit, and aligning the work with the plane;
- and
- re-gripping the work, which is aligned with the plane, again with the hand unit.
2 more elements
A method of controlling a robot that includes a hand unit which has a planar portion and which can grip a work at a position which is separated from the planar portion, the method comprising:
- gripping the work with the hand unit;
- and
- pressing the work and the planar portion together.
A robot comprising:
- a hand unit,
- wherein the hand unit includes a base portion, a planar portion which is disposed on the base portion, and finger units which are capable of gripping a work at a position which is separated from the base portion, and
- wherein the robot can perform an operation of gripping the work placed in a gravity direction with the finger units, an operation of inverting the hand unit such that the hand unit is positioned in the gravity direction of the work which is gripped with the planar portion, and an operation of dropping the work to the planar portion by reducing the grip force of the finger units.
A robot comprising:
- a hand unit,
- wherein the hand unit includes a base portion, finger units which can grip a work at a position which is separated from the base portion, and a planar portion which can move from the base portion to directions of the finger units, and
- wherein the robot can perform an operation of enabling the finger units to grip the work, and an operation of moving the planar portion in a direction of the gripped work and pressing the planar portion against the work.
A robot comprising:
- a hand unit,
- wherein the hand unit includes a base portion, a surface portion which is disposed on the base portion, and finger units which can grip a work, and
- wherein the robot performs a grip operation of gripping the work with the hand unit, a transfer operation of transferring the work to a predetermined position of the surface, a release operation of aligning the work with the surface in such a way as to drop the work to the surface by reducing a grip force of the hand units, and a re-grip operation of gripping the work again which is aligned with the surface with the hand unit.
