Abstract

A human-cooperative industrial robot having a base unit and a movable unit movably provided on or above the base unit. The robot includes a protection member composed of a material with a rigidity lower than rigidities of the base unit and the movable unit, the protection member covering a circumference of at least the movable unit of the base unit and the movable unit; and a detector provided on at least either the base unit or the movable unit to detect an external force input through the protection member.

Claims

1. A human-cooperative industrial robot comprising:

a base unit;

a movable unit movably provided on or above the base unit;

a protection member composed of a material with a rigidity lower than rigidities of the base unit and the movable unit, the protection member covering a circumference of at least the movable unit of the base unit and the movable unit; and

a detector provided on at least either the base unit or the movable unit to detect an external force input through the protection member.

2. The human-cooperative industrial robot according to claim 1, wherein

the protection member is fixed in close contact with an external peripheral surface of the base unit or the movable unit.

3. The human-cooperative industrial robot according to claim 1, wherein

the protection member is fixed with a clearance from an external peripheral surface of the base unit or the movable unit.

4. The human-cooperative industrial robot according to claim 1, wherein

the protection member is formed by laminating a plurality of layers having different rigidities.
