Abstract: A diagnostic system acquires operating condition information capable of identifying an operating condition of a robot arm. The diagnostic system acquires detection results of a plurality of sensor apparatuses installed in the robot arm. The diagnostic system estimates, by inputting the operating condition information acquired at a first point of time and the detection results of the plurality of sensor apparatuses acquired at the first point of time to a simulation model, the detection result of a particular sensor apparatus of the plurality of sensor apparatuses at the second point of time. The diagnostic system estimates a state of the particular sensor apparatus by comparing the detection result of the particular sensor apparatus at the second point of time, which is estimated, with the detection result of the particular sensor apparatus acquired at the second point of time.

Abstract: A sensor device is attached to, for example, a mechanical component. The sensor device includes a sensor unit, an output unit, and an energy harvesting unit. The sensor unit measures a condition related to the mechanical component. The output unit outputs information that is based on the measurement result from the sensor unit to the outside. The energy harvesting unit converts energy that exists in an external environment into electric power and supplies an electric power for operating at least one of the sensor unit and the output unit.

Abstract: A sensor device is attached to various products. The sensor device includes a sensor unit, a communication unit, a storage unit, a power storage unit, and an energy harvesting unit. The sensor unit measures a condition related to a product. The communication unit outputs information based on the measurement result from the sensor unit. The storage unit stores the measurement result from the sensor unit and the information output from the communication unit. The power storage unit supplies electric power for operating at least one of the sensor unit, the communication unit, and the storage unit. The energy harvesting unit converts energy of an external environment into electric power and charges the power storage unit.

Abstract: A joint mechanism includes: a first member; a second member; and a gear device that is provided between the first member and the second member and changes the number of revolutions at a predetermined ratio to transmit a drive force. The gear device includes a crank shaft on which a first eccentric portion is formed, a first oscillating gear that has first external teeth and an insertion hole into which the first eccentric portion is inserted, a carrier that retains the crank shaft rotatably, and an external cylinder that has an internal-tooth pin 3. The carrier and the external cylinder are configured to be displaced coaxially and relatively to each other due to oscillation of the first oscillating gear.
