The design and implementation of all-dimensional planar motion positioning system based on multi-sensor

With the widespread promotion of all-dimensional planar motion system, increasingly importance has been attached to the corresponding modules. This article introduces a kind of integrated module designed for positioning the planar motion system. The system contains two sensors, they're magnetic encoder and mems gyro chip. Magnetic encoder is used to record the distance of the two driven wheels while the gyro module is used to record the deflection angle. With the thought of differentiation, we decomposed continuous motion into many small pieces of linear motion to get the coordinate of the system. Another obvious merit is that the driven wheels can move up and down automatically according to the condition of the road, which made the calculation of the system's coordinate accurate.
