Aspect-based Sentiment Classification of Mobile Product Reviews

Most space probes receive the greatest amount of daily energy requirement from solarcells. Solar robotic arm panels are designed to increase energy efficiency in a space probe.To get the maximum amount of solar energy should be placed perpendicular to thedirection of radiation. This system radiation and energy sensors is used to control it. Themost of space are used probes to fix arm for solar panels. In this model has been used adual-axis robotic arm which is increased efficiency of received solar energy up to 30percent. The arm can adjust tilt and azimuth angels up to 45 degrees for solar panels. Thecontrol of system is based on adjusting tilt angel as monthly periodically and the rotationangle as daily. If any of control system axes disturb, the axis will return to zero anglemode, but the other axis will continue to its function. Solar meters and the photocells areused to design the optical control system. These sensors error rate are about 5 percent.
