Abstract: Based on the paddy field operating environment and the requirements of unmanned agricultural machinery operation, an electric-driven robot mobile platform was designed and constructed.The platform mainly includes a walking chassis and a control system.The walking chassis is composed of the main frame, the electric drive system,the walking assembly,the steering assembly,and the lifting mechanism.The control system is based on the STM32 F407 IGT6 as the main controller, using speed measuring encoders, angle sensors,AT9 S remote controls, and R9 D wireless modules. The remote control of the robot platform was realized. The platform was equipped with a GPS-RTK navigation system to perform trajectory tracking experiments.The results show that the remote control and trajectory control of the paddy field robot platform meet the requirements of unmanned agricultural machinery operations.
