摘要：
In order to achieve closed-loop control of multi-line information for mobile robot in greenhouse, DSP (TMS320LF2407)event handling output PWM signals and quadrature encoder pulse (QEP) circuit were introduced, the closed-loop control of speed and position about driven wheel motor was implemented, the wheel and vision platform scan motor were oriented. In this way, the controller could automatically make every motor work respectively (included direction, speed, and angle), and the robot itself as well as the vision platform could make corresponding responses.
