 The gyroscope（陀罗仪） was invented in 1852 by the French experimental physicist Leon Foucault (1819-1868) as part of a two-pronged investigation of the rotation of the earth. The better-known demonstration of the Foucault pendulum showed that the plane of rotation of a freely-swinging pendulum rotated with a period that depends on the latitude of its location. His gyroscope was a rapidly rotating disk with a heavy rim, mounted in low-friction gimbals. As the earth rotated beneath the gyroscope, it would maintain its orientation in space. This proved to be hard to do in practice because the frictional forces bring the spinning system to rest before the effect could be observed. The gimbal bearings also introduce unwanted torque. But, the principle is well-known to all children who move their toy gyroscopes about and observe that the spinning disk stays in the same orientationLevel（水平仪） will help you design and build homes which have less impact on the environment and are healthier, more comfortable, and have lower running costs.The Angle sensor（角度传感器）allows accurate measurement of angles between 0 and 270 degrees.  The shaft does not allow continuous rotation.  This sensor is useful in designs that have limited rotation and need to measure the angle with resolution down to one degree.  It can also be used as a knob to "dial in" a variable to your program.  This sensor must be connected to the  three wire converter brick   for proper operationThe Accel Sensor（加速传感器） lets your robot measure it's acceleration.  The sensor can also be used to measure tilt.  This is a two channel device that lets you measure acceleration or tilt along two perpendicular axisThe key to efficient bending lies in a bending angle sensor（倾角传感器）, which besides measuring automatically, adjusts the angle to the required rated value. The ACB angle sensor developed by TRUMPF can do both: measuring and adjusting in the process.
Every angle is automatically correct . Complicated and time consuming bending programme run-in phases are now a thing of the past. The system automatically and independently controls the change in the spring-back angle of different materials and material properties..
