A safety device according to the present disclosure includes a sensor that is attached to a self-propellable travel device or a robot provided to the travel device, is set with a given detection area on the basis of a position of the sensor, and detects an object existing within the given detection area. The safety device further includes a motion suppressing device that suppresses motions of the travel device and the robot, when the existence of the object within the given detection area is detected by the sensor, and an area changing device that changes the given detection area according to operating states of the travel device and the robot.

A manipulator system includes a manipulator configured for guiding an instrument. The system furthermore includes a controller configured to actuate the manipulator such that the instrument is pressed with a pressing force against a human body. A force reduction input device is provided separately from the manipulator and is operable by an operator to reduce the pressing force.

A deterioration diagnosis apparatus is for a mechanical apparatus including a power transmission mechanism that transmits power via a gear. The deterioration diagnosis apparatus includes: a storing unit that stores, in advance, a trend of change along with the operation of the mechanical apparatus, in consumption rate of an additive contained in lubricant used for the gear; and a determination unit that determines the period to be taken for the consumption rate of the additive to reach a predetermined value, based on the trend of change in the consumption rate of the additive.

According to one embodiment of the present disclosure, there is provided a transfer apparatus comprising at least one arm configured to support a substrate; at least one gear disposed at a joint that rotatably supports the at least one arm, the at least one gear rotating the at least one arm; and a detector disposed to face the at least one gear and configured to detect a temperature of the at least one gear without contacting the at least one gear.

A conveyance robot system according to the present disclosure includes an intrusion detection sensor that detects an intrusion of an object into the arm opening, and a distance sensor that measures a clearance distance indicating a distance between an arm entry/exit surface and a shelf, the arm entry/exit surface being a surface of the conveyance robot in which the arm opening is provided from among surfaces of the conveyance robot 1 constituting the safety cover, and the object being stored in the shelf. The distance sensor is disposed at a fixed height of the shelf in a horizontal direction and at a height of the shelf corresponding to a part to be measured.

Provided is a collaborative-robot risk assessment guidance device (1) including: an input device (2) that receives inputs from a user; a storage device (3) that stores information; a display device (4) that displays the information; and at least one processing device (5), wherein the processing device (5) prompts the user to input, by means of the input device (2), basic information including conditions for collaborating with people, prompts the user to select, by means of the input device (2), at least one candidate information item for hazard sources stored in the storage device (3) in association with the input basic information, performs a risk assessment on a basis of risk specifics information stored in the storage device (3) in association with the selected candidate information item for the hazard sources, determines whether a result of the risk assessment is at or below an acceptable risk, and displays, on the display device (4), countermeasure proposals for separating people and a collaborative robot without partitioning a space therebetween in a case in which the result of the risk assessment is not at or below the acceptable risk.

A fenceless system and method for automatically moving one or more items between a structure at a source location and a destination using a robot is provided. The system comprises a robot having an end effector to selectively grasp an item. A trajectory planning controller directs the robot to move the item between a source location and a destination. A touch sensor detects a contact between an external object and a surface of the robot or a surface surrounding the end effector; and a proximity sensor detects a person in proximity to the robot. A vision sensor detects a location and orientation of items to be moved. The robot moves in proximity to a person without a safety fence preventing the person from contacting the robot. The system adjusts a speed of the robot in response to detecting a person in one of a plurality of zones around the robot.

An apparatus, system and method capable of providing a bumper capable of providing decreasing reversionary impact forces upon an impacting collider as the bumper is compressed. The apparatus, system and method may include at least a bumper cover; and a scissor mechanism housed within the bumper cover. The scissor mechanism may comprise a forward extension member proximal and having a parallel axis that is at least substantially parallel to a parallel tangential axis of the bumper cover; a rear extension member substantially parallel to the forward extension member, and distal from the flexible bumper; at least left and right long scissor members that are rotatably and slidably associated with respective slots in the forward extension member, and that, are rotatably associated with the rear extension member; and at least left and right short scissor members that are rotatably associated with the front extension member, and that are rotatably associated with a respective one of the left and right long scissor members.
