  • Vibration Sensor
    Publication number: 20160184988
    Abstract: A handling device has a robot arm, the arm having a vibration sensor and a coupling device. The vibration sensor is mounted on the arm, and the coupling device is configured to conductively connect the vibration sensor to processing circuitry located remotely therefrom. A second handling device has a robot arm, the arm having a vibration sensor and a coupling device. The vibration sensor is mounted on the arm, and the coupling device is configured to connect the vibration sensor to power supply circuitry located remotely therefrom. A robot arm vibration sensor has coupling device for connecting the sensor to power and control circuitry. The coupling device is configured to allow the power and control circuitry to be disposed remotely from the sensor.

  • Apparatus and method for detecting position drift in a machine operation using a robot arm
    Patent number: 9195226
    Abstract: In an example embodiment, apparatus for detecting position drift in a machine operation using a robot arm, the robot arm being for operation on a semiconductor substrate, the robot arm and the semiconductor substrate being configured for relative movement therebetween, the apparatus includes an input for receiving an input signal from a sensor mounted on the robot arm; a detector for detecting, from the input signal, a detection of there being a predefined distance between the robot arm and the semiconductor substrate; wherein the apparatus is configured to determine, from the detection, whether there has been position drift.
