Design And Implementation Of Network Control Robot Based On MSP430

With the development of network,network technology and robot technology are rapidly integrated,and the technology of remote control robot is developing vigorously.The research time of network control robot in our country is relatively short,and most of the industrial development is based on 51 series single-chip computer.Among them,network congestion and poor chip stability are common problems in network transmission,which affect the security and stability of Network-controlled robots.Nowadays,most of the network control robot systems are designed with 51 single chip computer.The problems are that the stability of the chip is poor,the running speed is slow,and the scalability is poor.The MSP430F149,which is a mixed signal processor with ultra-low power consumption and RISC,is used as the main control chip.The remote control terminal transmits instructions to the remote host connected with MSP430.The remote host communicates with the single chip computer through serial port,and then controls the relay through the processing of the single chip computer,thus realizing the control of the remote robot.In addition,the network control robot is limited by the transmission quality of network signals.In many cases,when the robot is in danger,if the network congestion and other problems occur,the robot will be in danger.To solve this problem,the system adds a "brake" module for the robot,installs two infrared transmitters on the front of the car,and uses a timer to send a modulated infrared line(38KHz),and sends the signal data of the infrared receiver to the single chip computer.When the single chip computer detects "danger",the system will let the robot car perform parking action.Then a series of experiments are carried out to optimize the infrared hazard avoidance fuzzy algorithm.Finally,by using the instructions given by the Web terminal to the MSP430-based network control robot,the remote control of the robot's movement,stop,turn and other actions is realized.When the control network is congested or the delay is large,the test robot car can judge whether the car is in danger or not by the parameters obtained by the infrared sensor device carried by the vehicle head without receiving new instructions,and finally realize the emergency action of the robot.
