隨著科技發(fā)展及工業(yè)4.0 進(jìn)程推進(jìn),機(jī)械臂應(yīng)用范圍越來(lái)越廣,并演化出各種各樣的機(jī)械臂,如碼垛機(jī)械臂、焊接機(jī)械臂、裝配機(jī)械臂以及手術(shù)機(jī)械臂等。現(xiàn)利用solidworks 進(jìn)行三維建模,設(shè)計(jì)制作一款基于stm32f103c8t6 單片機(jī)的主從式桌面級(jí)機(jī)械臂,該機(jī)械臂包括一個(gè)主動(dòng)機(jī)械臂和一個(gè)從動(dòng)機(jī)械臂,采用藍(lán)牙傳輸信號(hào)方式進(jìn)行同步運(yùn)動(dòng),并且詳細(xì)介紹了該機(jī)械臂材料選擇、結(jié)構(gòu)設(shè)計(jì)、工作原理、組成部分和設(shè)計(jì)特點(diǎn)。With the development of science and technology and the advancement of Industry 4.0, the application range of the mechanical arm has become wider and wider, and various types of mechanical arms, such as palletizing robot arms, welding robot arms, assembly robot arms, and surgical robot arms, have been developed. Now using solidworks for 3D modeling, design and manufacture a master-slave desktop-level robot arm based on stm32f103c8t6 single-chip microcomputer. The robot arm includes an active robot arm and a slave robot arm, which uses Bluetooth to transmit signals for synchronous motion. The material Selection, structural design, working principle, components and design features of the manipulator are introduced.
數(shù)字示波器功能強(qiáng)大,使用方便,但是價(jià)格相對(duì)昂貴。本文以Ti的MSP430F5529為主控器,以Altera公司的EP2C5T144C8 FPGA器件為邏輯控制部件設(shè)計(jì)數(shù)字示波器。模擬信號(hào)經(jīng)程控放大、整形電路后形成方波信號(hào)送至FPGA測(cè)頻,根據(jù)頻率值選擇采用片上及片外高速AD分段采樣。FPGA控制片外AD采樣并將數(shù)據(jù)輸入到FIFO模塊中緩存,由單片機(jī)進(jìn)行頻譜分析。測(cè)試表明:簡(jiǎn)易示波器可以實(shí)現(xiàn)自動(dòng)選檔、多采樣率采樣、高精度測(cè)頻及頻譜分析等功能。Digital oscilloscope is powerful and easy to use, but also expensive. The research group designed a low-cost digital oscilloscope, the chip of MSP430F5529 of TI is chosen as the main controller and the device of EP2C5T144C8 of Altera company is used as the logic control unit. Analog signal enter the programmable amplifier circuit, shaping circuit and other pre-processing circuit. The shaped rectangular wave signal is sent to FPGA for measure the frequency. According to the frequency value to select AD on-chip or off-chip high-speed AD for sampling. FPGA controls the off-chip AD sampling and buffers AD data by FIFO module. The single chip microcomputer receives the data, and do FFT for spectrum analysis. The test shows that the simple oscilloscope can realize automatic gain Selection, sampling at different sampling rates, high precision frequency measurement and spectrum analysis.
