A system and method for detecting failure of a steering angle sensor include: a steering angle sensor (10), an angular position encoder (60) and an electronic control unit (20). The electronic control unit (20) reads an initial value of the steering wheel rotation angle signal and estimates a rotation angle of a steering wheel based on the motor rotation angle signal, the electronic control unit checks if a difference between an actual value of the steering wheel rotation angle signal and an estimated rotation angle of the steering wheel is smaller than a predetermined value or not, if the difference is bigger than the predetermined value, it means that the steering wheel rotation angle signal fails, and the estimated rotation angle of the steering wheel serves as a substitute signal and is sent to the electronic control unit.

A robot safety guard system for installation in the ground around a robot with an operating range is disclosed to include a plurality of sensor modules mounted on the ground beyond the operating range of the robot. Each sensor module includes 2 first sensors each providing a first sensing range. The first sensing ranges of the first sensors of the sensor modules are combined to define a first warning area. One of the sensor modules further includes a second sensor that provides a second sensing range. The second sensing range defines a second warning area beyond the first warning area. In this way, the robot safety guard system is constructed having low construction costs, fast reaction time and space-saving.

An electric gripper system includes a motor (10) driving a gripper mechanism (100), a sensor (20), and a control processing unit (30). The sensor (20) is assembled onto the motor (10) for generating a current position of the gripper mechanism (100). The control processing unit (30) has a control segment (36), a transceiver segment (32), an accessible segment (34), and a driving segment (38). The control segment (36) generates a target position according to a relative-position command value of the transceiver segment (32) and an absolute cumulative position of the accessible segment (34). The control segment (36) generates a driving datum based on a difference between the current position and the target position, and on a rotation rate of the motor (10). The driving segment (38) uses the driving datum to drive the motor (10) to move the gripper mechanism (100). With calculation among the relative-position command value, the absolute cumulative position, and the current position, the motor (10) is prevented from accumulating positional deviation.
