Robot system

1. A robot system, comprising:

a robot including a tactile sensor having a plurality of pressure sensors disposed at mutually different spatial positions, and a hand having the tactile sensor;

a tactile information circuitry configured to generate tactile information defined by a pressure distribution based on pressures detected by the plurality of pressure sensors and spatial positions of the plurality of pressure sensors, and output the tactile information;

a manipulator configured to make an operator sense the pressure distribution according to the tactile information outputted from the tactile information circuitry, and when the operator manipulates the manipulator, output manipulating information according to the manipulation; and

a robot controller configured to control operation of the hand of the robot according to the manipulating information outputted from the manipulator, wherein:

the hand of the robot is formed in a shape imitating a person's hand, and

the plurality of pressure sensors are provided to at least a portion of the hand of the robot, the portion corresponding to a palm of the person's hand.

2. The robot system of claim 1 , wherein

the manipulator includes:

a manipulator body being operated by the operator;

a plurality of mechanical stimulators, provided to the manipulator body corresponding to the plurality of pressure sensors, and configured to give a mechanical stimulation distribution according to the pressure distribution defining the tactile information outputted from the tactile information circuitry, to a hand of the operator who manipulates the manipulator; and

a manipulation sensor configured to detect the manipulation to the manipulator body, and output the detected manipulation as the manipulating information.

3. The robot system of claim 2 , wherein

the plurality of mechanical stimulators are a plurality of pressing elements configured to give a pressing-force distribution according to the pressure distribution defining the tactile information outputted from the tactile information circuitry, to the hand of the operator who manipulates the manipulator.

4. The robot system of claim 3 , wherein

the pressing element is a piezo-electric element.

5. The robot system of claim 2 , wherein

the plurality of mechanical stimulators are a plurality of oscillators configured to give an oscillating distribution according to the pressure distribution defining the tactile information outputted from the tactile information circuitry, to the hand of the operator who manipulates the manipulator.

6. The robot system of claim 2 , wherein

the manipulator body of the manipulator is a glove being worn by the operator.

7. The robot system of claim 2 , wherein

the manipulation sensor includes a displacement sensor provided to the manipulator body of the manipulator, and is configured to detect the manipulation to the manipulator body based on a displacement of the manipulator body detected by the displacement sensor.

8. The robot system of claim 1 , wherein

the at least portion of the hand of the robot, to which the plurality of pressure sensors are provided, includes portions that correspond to:

tips of fingers and a thumb of the person's hand or tips of the fingers of the person's hand;

palm-side portions between joints of the fingers and the thumb of the person's hand or between joints of the fingers of the person's hand; and

the palm of the person's hand.
