    • A slip sensor and method of sensing slip for object supporting structure such as a manipulator which includes a pair of relatively movable jaws having opposing jaw faces between which an object may be gripped are shown. At least one thermistor is located at the face of the object supporting structure, which thermistor is intimately engageable with the supported object. The thermistor is maintained at a substantially constant temperature, above ambient temperature, by the passage of current therethrough. The temperature of the gripped object adjacent the thermistor is raised to the above-ambient temperature by heat conduction thereto from the thermistor. With slippage of the gripped object between the jaws, the thermistor is exposed to another portion of the object which is at a different temperature than the temperature of the thermistor whereby the resistance of the thermistor changes. The thermistor is included in a temperature sensing and control unit which maintains the thermistor at a substantially constant temperature, and which has an output related to power supplied to the thermistor to maintain the set-point temperature. The output is digitized and supplied to a digital computer for determining whether or not slippage of the object between the jaws has occurred.
    • 滑动传感器和感测用于诸如操纵器的物体支撑结构的滑动的方法,其包括一对具有相对的夹爪面的可相对移动的夹爪,可夹持物体。 至少一个热敏电阻位于物体支撑结构的表面,该热敏电阻与被支撑物体紧密接合。 热电阻通过电流通过而保持在高于环境温度的基本上恒定的温度。 与热敏电阻相邻的被夹持物的温度通过从热敏电阻的热传导而升至环境温度以上。 随着被夹持物体在夹爪之间的滑动,热敏电阻暴露于物体的另一部分,该物体的温度与热敏电阻的温度不同,因此热敏电阻的电阻改变。 该热敏电阻被包括在温度感测和控制单元中,该温度感测和控制单元将热敏电阻保持在基本上恒定的温度,并且具有与提供给热敏电阻的功率相关的输出以保持设定点温度。 将输出数字化并提供给数字计算机,以确定是否发生了夹爪之间的物体滑动。

    • An electroadhesive device includes an outer surface adapted to interface with a surface of a foreign substrate, a plurality of electrodes (18), and a semi-conductive insulation material (20) disposed adjacent to at least one of the electrodes (18). Each electrode (18) has a respective conductive volume and is configured to apply a voltage at a respective location of the outer surface, and the difference in voltage between applied voltages includes an electrostatic adhesion voltage that produces an electro-static force between the device and the substrate (16) that is suitable to maintain a current position of the device relative to the substrate (16). The insulation material (20) can be polyurethane or any other suitable material having a resistance of about 109 to 1012 ohms*m. The insulation material effectively operates to expand the conductive volume of the electrodes (18) when they are actuated.
