Abstract

The invention discloses a two-wheel self-balancing driving system based on an embedded ARM. The two-wheel self-balancing driving system based on the embedded ARM comprises a left wheel, a right wheel, pedals, a motor driving system and a steering device, wherein the left wheel and the right wheel are connected through an axle, the steering device is connected with the pedals, the left wheel and the right wheel are respectively provided with a brushless direct current motor, the motor driving system is arranged above the axle and below the pedals, an embedded driving control system and two driving modules are arranged in the motor driving device, and the two driving modules are connected with the brushless direct current motor of the left wheel and the brushless direct current motor of the right wheel respectively. The embedded driving control system comprises a microcontroller stm32 single chip microcomputer, a power source, a gyroscope, an accelerometer, a current measuring device and a functional module, wherein the power source is connected with the stm32 single chip microcomputer, the gyroscope, the accelerometer and the brushless direct current motors, the gyroscope is connected with the accelerometer, the accelerometer is connected with the stm32 single chip microcomputer, and the stm32 single chip microcomputer is connected with the two driving modules. The two-wheel self-balancing driving system based on the embedded ARM has the advantages of being high in systematic cost-performance ratio, wide in application range, and capable of having large promotional value.

Description

technical field [0001] The invention relates to a two-wheel self-balancing trolley, in particular to an embedded ARM-based two-wheel self-balancing driving system. Background technique [0002] In recent years, the two-wheeled self-balancing trolley system has become an ideal platform for studying various controls, and a typical device for testing different control methods, strategies, and control capabilities, which has attracted widespread attention from robotics laboratories. The advantage of adopting embedded control system is that the system kernel is small, the specificity is strong, the system is simplified, and the cost of system development is saved. At present, all kinds of self-balancing trolleys in the market are mostly driven by brushed motors. As we all know, brushed motors have high noise, low efficiency and sparks. The scope of use of the balance trolley. Contents of the invention [0003] In order to solve the above problems, the purpose of the present i...
