Aiming at the torsional vibration of a space flexible bar system, a flexible bar system which consists of a flexible bar, a strain gauge sensor and a piezoelectric torsional actuator is proposed.

This paper presents the design and actual circuit of a computer control system for the North-Seeker with ARM7 (here LPC2292 is used) as core microprocessor and the flexible gyro as sensor.

The wireless sensor network node model in system programming is less in size, lower power and faster in velocity, but the wireless sensor network node model in microprocessor is more flexible.
